The physico-chemical parameters and plankton abundance of four artificial fish ponds in Omageyu Farms, Ijotun, Badagry, Nigeria was studied and analysed using standard methods monthly from June to December 2015. Water temperature, pH and dissolved oxygen ranged from 27.80 to 32.00°C, 6.90 to 7.40 and 6.80 to 10.00 mg/l, respectively in the four ponds. Water temperature, pH, and dissolved oxygen in Pond A were significantly different from Ponds B, C and D. Forty-five planktonic organisms, including 40 phytoplankton and 5 zooplankton species, were identified. Shannon Weiner index was highest for pond A = 2.824 and decreased in the order: pond C = 2.81, pond B = 2.797 and pond D = 2.767. Margalef’s index of species richness was greatest for pond D = 2.313 and least for pond A. Berger-Parker Dominance Index (BPDI) for the ponds decreased in order of ponds A = 0.2422, C = 0.2328, B = 0.192 and D = 0.1858. Total plankton in the four ponds showed positive correlation with dissolved oxygen. The class Chlorophyta was the prevalent group in the four ponds. The results showed that physico-chemical parameters have an influence on the distribution and diversity of plankton in earthen fish ponds. Key words: Clarias gariepinus, earthen ponds, physicochemical parameters, phytoplankton, zooplankton.

Characteristics of fish farming practices and agrochemicals usage therein in four regions of Cameroon

Cameroon plans to reduce massive fish imports by developing aquaculture which appears to be a great solution to the massive demand for animal protein. Therefore there is a need to assess fish farming practices and agrochemicals usage. A cross-sectional survey employing questionnaires was used to collect information from 107 farmers in the centre, south, littoral, west regions of Cameroon between April and September 2016. The results of the study showed that fish farmers were mainly men (93%) with 49.5% as small scale farmers, 83.3% practiced earthen fish pond, and about 30% practice integrated fish farming with poultry (18.6%) piggery (16.7%) and crop farming (10.7%). Feeding practices are characterized by the use of locally formulated powdered feeds (31.7%), animal manure, chicken droppings (20.5%) and pig dung (18.7%). Concerning fish health management, few farmers (24.3%) refer to a veterinarian for prescription and 51% used agrochemical products like liming materials, fertilizers and veterinary drugs. Tetracyclines are the most used for curative purposes. Good fish farm management practices, successful fish health management, and periodical monitoring will contribute to produce safer fish products. Results from this study should encourage an effective monitoring of chemicals contaminants in fish farming in Cameroon.

Evaluation of phytoplankton diversity in periphyton based aquaculture system

This study was done to determine the impact of rice straw as a substrate for periphyton production and phytoplankton biodiversity in earthen fish ponds belongs to the world fish center. The ponds have the same area of Six 1000 m2 and the depth of water 1m. The ponds cultured with mono six Nile tilapia fry in the rate of 3 fry/ m2. All ponds were fertilized with dry chicken manure in the rate of 15 kg/pond/week, and divided into two treatments, each of 3 replicates; the first treatment (T1), the substrate free control, while second treatment (T2) received 45 kg dry rice straw/pond. The samples were collected monthly from May to December 2017. The quantitative measurements for phytoplankton showed that total count of phytoplankton in water was higher in T1 than T2. The rice straw was effective for controlling growth of cyanophyceae compared to controls, and was capable for inhibiting the growth of Microcystis. Phormidium, Merismopediam, Gloeocapsa, Lyngbya and Chlorella, but Chrococcus, Synedra and Navicula sp. had improved growth in the presence of rice straw.Concerning periphyton the total count was (2103.68 x 106 org. /m2 as an average). And Chlorophyceae represent the dominant group with average (1577.07 x 106 org. /m2). The biodiversity index of overall phytoplankton genera Taxa evenness were (1.95 and 0.51) respectively in T2 which indicates that there is a high biodiversity of algae compared to T1 (1.76 and 0.42). The results of this investigation indicated that rice straw could introduce an accessible practical and commercial method to increased phytoplankton biodiversity.

Effects of water physico-chemical parameters on tilapia (Oreochromis niloticus) growth in earthen ponds in Teso North Sub-County, Busia County

Small-scale fish farmers in developing countries are faced with challenges owing to their limited information on aquaculture management. Nile tilapia farmers in Teso North Sub-County recorded lower yields than expected in 2009 despite having been provided with required inputs. Water quality was suspected to be the key factor responsible for the low yields. This study sought to assess the effects of earthen pond water physico-chemical parameters on the growth of Nile tilapia in six earthen fish ponds under semi-intensive culture system in Teso North Sub-County. The study was longitudinal in nature with pond water and fish being the units of analysis. Systematic sampling was used to select five ponds while a control pond was purposively selected based on its previously high harvest. Four ponds were fed by surface flow and two by underground water. Each pond was fertilized and stocked with 900 fry of averagely 1.4 g and 4.4 cm. Physico-chemical parameters were measured in-situ using a multi-parameter probe. Sixty fish samples were randomly obtained from each pond fortnightly for four months using a 10 mm mesh size and measured, weighed and returned into the pond. Mean range of physico-chemical parameters were: dissolved oxygen (DO) 4.86–10.53 mg/l, temperature 24-26 °C, pH 6.1–8.3, conductivity 35–87 μS/cm and ammonia 0.01–0.3 mg/l. Temperature (p = 0.012) and conductivity (p = 0.0001) levels varied significantly between ponds. Overall Specific Growth Rate ranged between 1.8% (0.1692 g/day) and 3.8% (1.9 g/day). Ammonia, DO and pH in the ponds were within the optimal levels for growth of tilapia, while temperature and conductivity were below optimal levels. As temperature and DO increased, growth rate of tilapia increased. However, increase in conductivity, pH and ammonia decreased fish growth rate. Temperature and DO ranging between 27 and 30 °C and 5–23 mg/l, respectively, and SGR of 3.8%/day and above are recommended for higher productivity.

Development of Polyculture and Integrated Multi -Trophic Aquaculture (IMTA) in Israel: A Review

Israeli aquaculture began in the 1920s, with common carp monoculture. This was followed by polyculture of carp with tilapias, grey mullet, and planktivorous carp. Scientific research on polyculture started in the 1950s and has since contributed to the global science and practice of green water aquaculture, especially with novel polyculture approaches and concepts. Today, the industry is characterized by intensive freshwater polyculture, implemented in earthen fish ponds and reservoirs. In the Mediterranean coastal plain, fresh, brackish, and marine water polyculture is carried out in semi-intensive fishponds. Polyculture in Israel is an entrepreneurial activity that combines ecological principles of Chinese polyculture with local technologies and objectives. The Biofloc approach (active suspension ponds, ASP), periphyton, and aquaponics, were developed in the 1980s in response to rising public and policymakers’ concerns and regulations on land use, pollution, use of chemicals, and organic manures. R&D on marine integrated multi-trophic aquaculture (IMTA) systems began in the early 1970s at the National Center for Mariculture (NCM) in Eilat. It started with sea bream and mullet in earthen seawater ponds, whose plankton-rich water recirculated through bivalve and macroalgae biofiltration modules. An advanced form of the concept was deployed in the early 1980s and was studied in detail using nutrient budgets. Several system models with fish, bivalves, and algae, on small and pilot scales, were studied and quantified. Abalone, sea urchins, shrimp, brine shrimp, Salicornia, and periphyton, were added to the Eilat marine IMTA models, beginning in the 1990s. Upon entering the third millennium, Israeli research further examined the relationship between the sustainability and economics of IMTA in world aquaculture.

Influence of alum on cyanobacterial blooms and water quality of earthen fish ponds.

Eruption of blue-green algal blooms occurs frequently in eutrophic lakes and fish ponds, with associated unpleasant odor and horrid scums. In the present study, we conducted a pre-test experiment in 3 m(3) outdoor concrete ponds to determine the optimum concentration of aluminum sulfate (alum) required for reduction of the cyanobacterial blooms without negative effect on fish growth. As a consequence, 10 mg L(-1) alum was named as the optimum concentration that was applied in 1000 m(3) earthen fish ponds. Obtained results showed that Secchi disc values significantly increased from 10 to 24 cm after 14 days of alum application. Alum-treated ponds showed a reduction in total phytoplankton counts by 94 and 96% compared to the corresponding controls after 10 and 14 days, respectively. Abundance of blue-green algae in the treated ponds was decreased by 98% compared to the corresponding control after 14 days of alum application. Consequently, dissolved oxygen, pH, total phosphorus, orthophosphate, and chlorophyll "a" content declined significantly. Our study revealed that using 10 mg L(-1) of alum is an effective way to control cyanobacterial blooms in eutrophic waters, especially in fish ponds, without negative effect in water quality.

The microbial profile of some concrete and earthen fish ponds within the Niger delta region was evaluated. The results of physico-chemical properties of the water samples showed that alkalinity values were significantly higher in concrete ponds (99.7±47.1 to 150±69.7) than (18±6.9 to 24±14.5 mg/L) in earthen ponds. Electrical conductivity values varied significantly between the ponds with (200±84.1 to 290±74.9 µs/m) in concrete ponds and (18±6.9 to 24±14.5 µs/m) in earthen ponds. Sulphate concentrations were higher in concrete ponds (0.25±0.36 to 1.53±14.9 mg/L) than (0.25±0.36 to 0.4±0.77 mg/L) in earthen ponds. The mean total heterotrophic bacteria count was higher in concrete ponds (6.5×105 to 7.4×105 cfu/ml) than in earthen (6.3×105 to 6.5x105 cfu/ml) ponds. The mean fungal count ranged from 2.11×105 to 2.25×105 cfu/ml in concrete pond and (1.8×105 to 2.4×105 cfu/ml) in earthen ponds. The bacterial genera isolated from the ponds were Escherichia coli, Staphylococcus sp., Aeromonas sp., Streptococcus sp., Salmonella sp., Vibrio sp., Shigella sp., Proteus sp., Pseudomonas sp., Klebsiella sp. Enterobacter species occurred only in concrete pond, while Serratia species occurred in earthen ponds. The fungal genera isolated from both the concrete and earthen ponds were Aspergillus sp., Penicillum sp. and Cladosporium sp. The genera, Fusarium sp. and Mucor sp were isolated only from earthen ponds. The study revealed that the ponds were grossly contaminated with pathogenic microorganisms which poses a risk to human health, thus of significant public health concern. Key words: Heterotrophic bacteria, fish ponds, fungal isolates, pathogens, physico-chemical properties.

Physico-Chemical Analysis of Fish Pond Water in Freshwater Areas of Bayelsa State, Nigeria

The study of Physico-chemical parameters in earthen fish ponds in five Local government areas in Bayelsa State, Nigeria was conducted to determine the quality of water for pond fish culture from June to October, 2005. Water samples were collected from the ponds and analyzed using standard laboratory methods and procedures. The results showed variation in the observed parameters at the different sampling stations. Temperature ranged from 24.9+ 0.3 o C25.3+0.30 o C, pH 6.24+ 0.02-6.68+0.10 and Ammonia-nitrogen (NH 3-N), 0.34+0.20-0.55+0.20mg/l. Dissolved oxygen values were 2.8+0.20-6.6+0.18mg/l, Biological oxygen demand ranged 2.9+0.60-4.52+0.90mg/l and Total alkalinity as 43.1+18.093.70+46.53mg/l. Total dissolved solids varied from 27.9+4.7-145.40+91.01mg/l while Total hardness was 19.7+4.144.3+15.07mg/l and Turbidity as 20.6+3.2-45.1+15.07ppm. Electrical conductivity was from 117.3+91.01378.4+130.2µmhos/cm. The values for NH 3-N were higher than accepted values for fish culture while those of other parameters favoured good fish production. The observations in this study suggest that pond fish production in some freshwater areas of Bayelsa State in Nigeria could be practiced without adverse effects posed by the quality of water.

COMPARATIVE EVALUATION OF ECONOMIC BENEFITS OF EARTHEN FISH PONDS AND CONCRETE TANKS IN AQUACULTURE ENTERPRISES IN OYO STATE, NIGERIA

The study focused on the comparative evaluation of economic benefits of earthen fish ponds and concrete tanks in aquaculture enterprises in Ibadan, Oyo state. Primary data were collected with the aid of structured interview schedule, administered through personal interviews and observations to elicit information from 100 fish farmers using purposive and convenience sampling procedure. Data collected were analyzed using descriptive, budgetary and inferential statistics. The study revealed that the mean age, male, married, household size, educated and fish farming experience were 41 years, 83.0%, 87.0%, 5 persons, 96.0% and 8 years, respectively. Earthen fish ponds users earned mean revenue of N3,322,189.85 with gross margin of N2,188,397.89 while concrete tank users earned N2,412,271.08 with gross margin of N1,413,299.46. The results showed profitability indices (0.61 and 0.47), Variable Cost ratio (0.35 and 0.30), Benefit Cost Ratio (2.55 and 1.89), Gross ratio (0.40 and 0.54) and Expenses structure ratio (0.13 and 0.23) for both the earthen ponds and concrete fish tanks, respectively. There were significant differences (t = 42.53, p0.05) between the profit level of earthen fish ponds and concrete tanks. Major constraints affecting economic status of the respondents were high cost of quality feed, insufficient funds, poaching and poor marketing channel. In conclusion, aquaculture is a more profitable and viable business regardless of the culture system. Government should assist the fish farmers by subsidizing feeds cost, granting and monitoring of loan.

Zooplankton abundance and diversity of fishponds exposed to different management practices

The taxonomic composition and community structure of zooplankton faunae of selected earthen fishponds in Ife North Local Government Area of Osun State, Nigeria were investigated for a period of two years sampling every other month. The study was based on three sets of fishponds with regards to fertilization practice and water flow regime. These include non flow-through ponds that received organic and inorganic fertilizers (FNF); flow-through ponds that received organic and inorganic fertilizers (FF) and unfertilized flowthrough ponds. The zooplankton fauna of the fishponds comprised of 81 species belonging to three phyla namely Rotifera (62 species belonging to 16 families and two orders), Arthropoda (6 cladocerans, 2 copepods, 6 ostracods, 4 insecta and one arachnid species) and Protozoa which was represented by only one species. Zooplankton species richness indices were generally higher in the flow-through ponds than in the non flow through ponds with some species occurring only in the fertilized flow-through ponds. The flow-through pond had the highest number of species 54, while the least number of species 37 was recorded from the non flowthrough pond. The fertilized non-flow-through ponds also had the .highest mean abundance of 36762 ± 56162 ind/m 3 , followed by fertilized flow-through ponds (34346 ± 40784 ind/m 3 ) and non-fertilized flow-through ponds (16006 ± 41263 ind/m 3 ) descending order. The means in zooplankton abundance among the ponds were, however, not statistically significant. The fertilized ponds supported zooplankton abundance while continuous water flow as observed in the flow-through had direct influence on diversity and species richness. Hence to achieve the desired effect of pond fertilization on its primary productivity, this must be accompanied by adequate water flowage especially in shallow fish ponds. Keywords: Zooplankton, community structure, diversity, fish ponds, fertilization.

Characterisation of potential aquaculture pond effluents, and physico-chemical and microbial assessment of effluent-receiving waters in central Ghana

An understanding of specific aquaculture systems and the impacts of their management practices leads to sound and cost-effective policies to protect the aquatic environment. Water samples were collected in 2009 from fish ponds, streams that receive effluents directly from ponds and reference streams in Ghana to assess potential environmental impacts of pond aquaculture. Although relatively dilute, fish ponds had higher levels of all physico-chemical variables measured compared to those of locations upstream and downstream of farms, and to reference locations. Total nitrogen and BOD5 were most clearly statistically significant. Of 292 earthen fish ponds surveyed in central Ghana, approximately 92% were used for either Oreochromis monoculture or Oreochromis–Clarias polyculture. These had similar pond water (i.e. potential effluent) quality but different management practices. The study ponds had the potential to pollute effluent-receiving streams, but their actual impacts will depend on how pond effluents are managed. Conventional treatment of effluents from these small-scale, low-volume operations, which discharge relatively dilute effluents infrequently, might not be cost-effective.

A Comparative Study on Physico-Chemical Characteristics and Phytoplankton Abundance between a Concrete and an Earthen Fish Pond in A.B.U., Zaria, Nigeria

Fish culture is a cheap source of animal protein for many households in Nigeria and water quality is a crucial factor in fisheries. The abundance of phytoplankton and physico-chemical parameters of two fishponds in the Department of Biological Sciences, Ahmadu Bello University, Zaria, Nigeria was studied fortnightly from the month of May to July 2011. The range value (means ± S.E) for physico-chemical characteristics observed are; Water temperature in pond A ranged from 25 0 C to 30.8 0 C (28.06 ± 1.96 O C), pond B ranged from 25 O C to 32.2 O C (28.78 ± 1.71 O C). Electrical conductivity in pond A ranged from 0-22 us/cm (118.50 ± 97.72) and pond B 0 to 169 us cm -1 (80.20 ± ± ± ± 73.67). Total Dissolved solids, pond A

Microbial assessment of selected earthen fish ponds in western Kenya

Water-borne infections are among the most recent emerging and re-emerging infectious diseases throughout the world. WHO estimates that 80% of all illnesses in the world are caused by water-borne disease pathogens that thrive due to inadequate sanitation and polluted water. This study determined the presence of enteric microbes in medium earthen fish farm ponds and waters in the region. Fifty-seven Oreochromis niloticus L. and 36 water samples were collected over three months from 12 ponds within Maseno and Luanda Division. Sixty-six enteric microbes were found – Vibrio hollisae (18.2%), Proteus vulgaris (12.1%), Yersinia spp. (7.6%), Salmonella typhi (7.6), Aeromonas hydrophilia (7.6%), Edwardsiella tarda (6.1%), and Escherichia coli (6.1%) were the most isolated Enterobacteriaceae from water. Fifty enteric microbes were collected from fish intestines; Citrobacter freundi (62%) and Proteus spp. were the most common. Thirty-nine bacteria were isolated from the macerated fish flesh with Citrobacter spp., Proteus spp. and Pseudomonas being the most common. Water temperature, salinity dissolved oxygen and pH were within the expected range. Earthen fish ponds harbor enteric microbes that could be pathogenic to humans, although they had low faecal bacterial indicators signifying minimal contamination from human waste.

Fish culture aimed at high production through intense culture practices often leads not only to the alteration in water quality but also to severe disease problems.  The accumulation of organic wastes deteriorates water quality and encourages the proliferation of pathogenic microorganisms.  To avoid these problems, probiotics are used as bioremediation tool. The present study was aimed to know the changing patterns of beneficial and pathogenic bacterial loads and water quality in fish ponds treated with pond probiotics. For this study, three earthen fish ponds, were cultured Pangasius sutchi, Catla catla and Labeo rohita, located in Balliparru near Machilipatnam in Krishna District, Andhra Pradesh, India were selected and studied for a culture period during 2009 to 2010.  Two ponds were treated with probiotics having Nitrosomonas (1.62 kg/ha) and Nitrobacter (0.82 kg/ha) species and one pond was kept as control. During the culture period (August 2009 to July 2010), water quality parameters and the populations of total heterotrophic bacteria (THB), beneficial bacteria (Nitrosomonas and Nitrobacter species) and pathogenic bacteria (Pseudomonas) in water were analyzed. It was observed that in treated ponds, THB and beneficial bacterial load increased and pathogenic Pseudomonas load decreased. The bacterial population changed during every fortnight sampling of the culture period. The changing patterns of different bacteria in treated and control ponds were compared and discussed. The concentrations of ammonia, nitrite and phosphates were observed to be low in treated ponds than in the control pond. The present study revealed that the probiotics are instrumental in maintaining good water quality, higher beneficial and lower pathogenic bacterial loads in fish ponds.   Key words: Probiotics, fish ponds, physico-chemical parameters of water, total heterotrophic bacteria, nitrifying bacteria.  

Risk assessment of parasitic helminths on cultured Nile tilapia (Oreochromis niloticus, L.)

Disease outbreaks constrain aquaculture development. Knowledge on the potential risks of pathogens to farmed fish can help in designing management strategies for increased aquaculture productivity and sustainability. This study compares the helminth infections in reservoirs and therein operated cages as well as earthen fish ponds and the feeding stream in order to assess the significance of life cycle style and water sources in parasite transmission. In addition field experiments were setup to determine loading time and transmission rate. From 650 fish examined, 8 helminth species were recorded (3 from caged- and all 8 from pond-raised fish). The parasite community was dominated by trophically-transmitted species in both culture systems indicating the importance of trophic pathway in helminth transmission. The occurrence of trophically-transmitted helminths in caged-fish was positively related to their prevalence in reservoir-dwelling hosts indicating the importance of water supply in spread of helminths. The prevalence in pond-raised fish was higher than in stream-dwelling ones suggesting the presence of local sources of infective stages within ponds. Risk assessment revealed that monogeneans are high-risk parasites while heteroxenous helminths pose low to negligible threats to farmed fish. Although, cages appeared safer to heteroxenous parasites than ponds, their location in the water body, especially the distance from shores and depth is critical.

Rearing Rabbits Over Earthen Fish Ponds in Rwanda: Effects on Water and Sediment Quality, Growth, and Production of Nile Tilapia Oreochromis niloticus

Nine earthen ponds of 400 m2 each, were stocked with 800 mixed sex Nile tilapia Oreochromis niloticus fingerlings (14 g mean weight stocked at 2 fish/m−2) and fertilized with rabbit droppings from rabbits reared over fish ponds and stocked at three different densities: T1 = one, T2 = two, and T4 = four rabbits per 100 m2 of pond. After 152 days, results from this integrated rabbit/fish system showed: 1) increasing nutrient content of all ponds in the three treatments except for nitrates, which decreased with time and, 2) good water quality in terms of pH, dissolved oxygen, and turbidity. Fish mean weight at harvest and fish yield were higher in ponds fertilized by the highest rabbit stocking rate: 42.32 g and 6.35 ± 1.0 kg/are, respectively (1 are = 100 m2).

Plankton distribution and diversity: a case study of earthen fish ponds in the Obubra Campus of Cross River University of Technology

Our knowledge of the consumption of plankton by fish is still fragmentary. Trophic links between fish and plankton are often loose because plankton is a changing assemblage of pelagic organisms of valuable nutritional value. The objectives of the study were to determine the distribution and diversity of planktons in the fish ponds. Water samples for plankton analysis were collected monthly (January – December), along with water samples used for the determination of physico-chemical parameters in 250ml bottles in Ponds 1,2 and 5. The freshwater sample was mixed gently and pipetted into 5ml plankton chamber containing 2 drops of Lugol’s solution. The Lugol’s solution which served as fixative also enhanced sedimentation of the organisms and was left overnight before analyzing plankton using Zeiss inverted plankton microscope and plankton determination keys. Data was analyzed using Shannon-Weaner diversity index, species richness, means and analysis of varians (ANOVA).The results showed that the highest species richness for dry season phytoplankton value of 27 was recorded in Pond 2, with the highest Shannon-Weaner diversity index value of 0.5401 in pond 5. Merismopaedia elegans with 3,434 in pond 2 was the most abundant phytoplankton species and chlorophyceae the most dominant taxa. The rainy season zooplankton species richness values (5 in pond 2) were higher than that of the dry season (3 in pond 3) with the highest Shannon-Weaner index value of 0.3501 recorded in pond 1. The most abundant zooplankton species Asplanchna species 57 was recorded in pond 2. Significant differences (p
