Effect of cinnamon (Cinnamomum verum) extracts on the growth and protection ability of tilapia (Oreochromis spp.) against Streptococcus agalactiae

This study was conducted to investigate the effect of cinnamon (Cinnamomum verum) extract mixed to feed on growth parametersand the ability to protect tilapia against Streptococcus agalactiae isolated from infected tilapia (Oreochromis spp.) in Cu Chi district, Ho Chi Minh city. Cinnamon extract was mixed to feed with doses of 10, 20, and 40 g/kg feed. Fish were intraperitoneally injected with 0.1 ml of 1.8x104 CFU/ml of S. agalactiae. The negative control was injected with 0.1 ml of physiological saline. The results showed that the cinnamon extract (C. verum) mixed at the three above levels was shown to be safe for the growth and survival rate of tilapia. Moreover, cinnamon extracts well mixed at 20 g/kg feed proved the highest protection (with the relative percent survival (RPS) value being 51.4%). The cinnamon extract can be considered a potential herbal extract for the prevention of disease caused by S. agalactiae in tilapia.

Digestibility of Feed Supplemented with Common Pleco Meal and Its Impact on The Growth of Nile Tilapia (Oreochromis sp.)

Common pleco is a wild fish whose habitat occupies a lot of reservoir areas and public waters in Indonesia. The amount is abundant and not consumed by humans, is a great potential to be used as a source of animal protein in fish feed. The purpose of this study was to evaluate the digestibility of common pleco fish meal in artificial feed for nile tilapia (Oreochromis niloticus.) The study was carried out at the Aquaculture Laboratory Hatchery, Faculty of Fisheries and Marine Sciences, Universitas Padjadjaran, while the manufacture of common pleco meal, proximate analysis of feed ingredients and the test feed was carried out by the Laboratory of Chemistry and Animal Feed, Faculty of Animal Husbandry, Universitas Padjadjaran. The design used in this study was a Completely Randomized Design (CRD) consisting of 5 (five) treatments and 3 (three) replications. The treatment given was the addition of common pleco flour in artificial feed at 0%, 5%, 10%, 15% and 20%. The parameters observed in this study consisted of digestibility, growth rate, and water quality. The results of the research on some of these parameters indicate that the addition of common pleco meal can still be used in artificial feed up to 10%. The tilapia studied had the highest relative growth with a value of 0.218%. The digestibility level of the studied feed reached a value of 85.256%, and the water quality studied was still within the safe tolerance limits for fish farming. Based on the results of this study, the negative effect on the survival rate of tilapia did not occur until the addition of common pleco flour to artificial feed reached 10%. Thus, the fish meal has the potential as an alternative to fish meal in fish feed formulations.

Effects of faba beans (Vicia faba L.) on growth performance, textural quality and physiological indices of tilapia (Oreochromis niloticus)

Tilapia (Oreochromis niloticus) is a fish species farmed in freshwater aquaculture worldwide, for which increased intensification has caused many problems including poor muscle quality. The tilapia fed faba beans (Vicia faba L.) had improved fish crispiness and firmness, but faba beans contain a variety of antinutritional factors which potentially interfere with certain growth performance and physiological indices. There little is known about the growth performance, and physiological indices of tilapia fed with different amounts of dietary faba bean. This study was conducted to evaluate the effects of faba bean on growth performance, histological analysis, physiological indices and related gene expression profiles in tilapia (initial mean body weight of 463.86 ± 16.51 g). A basal diet (diet 1) containing no faba beans was fed to a control group and four other diets were produced by inclusion of 40%, 50%, 60% and 70% faba beans as diet 2, 3, 4, and 5, respectively. The results showed that there was no significant effect of dietary faba bean on the survival rate of tilapia. A reduction in the body weight, weight gain rate (WGR) and specific growth rate (SGR) were observed for tilapia fed diets 2, 3, 4 and 5 compared with the control. In the trial groups fed diets 2, 3, 4 and 5, a significant increase in the liver somatic index (LSI) and viscerosomatic index (VSI) was observed compared to those fed the control diet at 90 days (P < 0.05). Tilapia fed faba beans had higher muscle fiber density, wider spaces between muscle fibers and smaller fiber diameter and area, with the most difference in tilapia fed diet 4. The glutathione peroxidase (GSH-Px) was significantly decreased compared with the control group in both serum and liver (P < 0.05), while superoxide dismutase (SOD) was not significantly different. Compared with the control group, glucose 6-phosphate dehydrogenase (G6PD) activities of dietary faba bean groups were significantly decreased (P < 0.05). The aspartate transaminase (AST) and alanine aminotransferase (ALT) were significantly increased by dietary faba bean. Dietary faba bean did not affect acid phosphatase (ACP) and alkaline phosphatase (AKP). In summary, dietary faba bean at an optimum level of 60%, improved muscle fibers but had negative effects on growth performance and physiological parameters in the tilapia. The results would contribute to an understanding of the growth, textural quality, and physiological parameters affecting the tilapia crisping process.

BUDIDAYA IKAN NILA JATIMBULAN (Oreochromis sp) DENGAN SISTEM SEMI INTENSIF

Low growth performance and survival rate of tilapia is the main problem in tilapia culture especially Nile Jatimbulan. Growth performance of Nile tilapia is highly affected by genetic materials, food quality, stocking density, feeding rate and frequency and environmental factors such as water quality. Semi intensive system in earthen pond were used in this study. Earth pond contain various of organisms which support the growth performance of fish and phytoplankton. In addition, waterwheel with a power of 0.5 HP were added to increase the amount of dissolved oxygen in the pond. To improve water quality and performance of tilapia, EM4 probiotic were applied. This study showed the growth rate of jatimbulan is 2.94 grams, SR 80% and FCR value of 0,6. Jatimbulan tilapia were obtained after 90 days of culture is 6 tons with an average of body weight 250-300 grams.

Utilization of Fermented Eucheuma cottonii Flour in Feed for Cultivation of Tilapia (Oreochromis niloticus)

This study heads to analyze the effect of adding fermented E. cottonii flour as raw materials on the growth and survival rate of tilapia. The method used in this study is an experimental method with a Completely Randomized Design (CDR) using 4 treatments and 3 replications. The treatments tested consisted of 0% E. cottonii flour (P1/Control), 4% fermented E. cottoni flour ( P2), 8% fermented E. cottoni flour (P3), 12% fermented E. cottoni flour (P4). Parameters observed were specific growth rate, absolute weight growth, absolute length growth, feed conversion, feed efficiency and tilapia fry survival. Data were analyzed using analysis of variance (ANOVA) with 95% confidence level. The results showed that the addition of E. cottonii seaweed flour fermented by tape yeast in the feed formulation could affect the efficiency of feed utilization but did not affect the growth, feed conversion and survival rate of tilapia. The addition of E. cottonii flour fermented by tape yeast to a concentration of 8% (P3) gave the best results because it could increase the efficiency of tilapia feed by 71.16% to 73.9%.

Effects of two host-associated probiotics Bacillus mojavensis B191 and Bacillus subtilis MRS11 on growth performance, intestinal morphology, expression of immune-related genes and disease resistance of Nile tilapia (Oreochromis niloticus) against Streptococcusiniae

The intensification and diversification of production systems have increased the incidence of diseases, which are usually treated with antibiotics. However, its use should be restricted due to the increasing prevalence of antibiotic-resistant bacteria. Probiotics represent therefore an alternative environmentally friendly strategy for improving growth and disease resistance in aquaculture. Considering that host-derived probiotics may offer greater advantages than those from other environments in terms of safety and efficacy, two potential host-associated probiotic strains (Bacillus mojavensis B191 and Bacillus subtilis MRS11) were used in the present study, which were previously isolated from intestinal mucus of Nile tilapia (Oreochromis niloticus). This study was conducted to assess the effects of dietary administration of two Bacillus strains on growth performance, intestinal morphology, immunity, and disease resistance of Nile tilapia. A total of 375 fish were randomly divided into five groups in triplicate. Nile tilapia were fed a basal diet (control group) or a basal diet supplemented with Bacillus mojavensis B191 (BM) or Bacillus subtilis MRS11 (BS) spores at different concentrations of 1 × 106 (BM6 and BS6, respectively) and 1 × 108 (BM8 and BS8, respectively) CFU/g of feed for 60 days. Moreover, the survival rate of tilapia upon challenge with Streptococcus iniae was determined following the feeding trial. After the feeding trial, the growth performances were significantly improved in all probiotic-fed groups, with the BS8 group being the highest. Light and electron microscopy observations revealed elevated goblet cells, intestinal villus length (except BM8), microvilli length, microvilli density, and perimeter ratio increase in the intestine of all probiotic-fed groups compared with the control group. Regarding the expression analysis, HSP70 gene was only up-regulated in the BM8 group and a general trend of up-regulation of some immune-related cytokines (TGF-β, IL-10, TNF-α and IL-1β) was observed in all probiotic-fed groups. Likewise, the best protection against Streptococcus iniae was observed in the BS8 group, followed by BS6, BM6 and BM8 groups. Altogether, dietary probiotic supplementation with BS8 and BM6 may improve growth performance, intestinal morphology, immunity, and disease resistance in Nile tilapia.

Growth Performance of Tilapia Oreochromis niloticus with the Provision of GDM Probiotics maintained with the Biofloc System

Tilapia is one type of freshwater fish that has economic value. This type of fish has good adaptability and fast growth. One of the problems in tilapia cultivation is that probiotics have not been utilized in the maintenance media with a biofloc system. This study aimed to determine the dose of probiotic supplementation in the formation of bioflocs on the growth and survival of tilapia. The research was conducted at the Educational Pond, Bosowa University, Maros Regency. The test animals used were tilapia seeds measuring 2-3 cm long. The stocking density of 3 seeds/L were kept in a basin with a capacity of 80 L filled with 60 L of water. The treatment tested was GDM probiotic supplementation in media with doses of A 5%, B 6%, C 7%, and D 0 %. The study used a completely randomized design with 4 treatments and 3 replications so that there were 12 experimental units. Seeds were reared for 60 days by feeding Hi-Pro-Vite FF-99 as much as 3% of body weight biomass per day. The results showed that GDM probiotic supplementation with different doses significantly affected the growth and survival of tilapia. Supplementation of GDM probiotics 5%, 6% and 7% in the media gave the same effect on the growth and survival of tilapia but significantly different from the treatment without probiotics. The highest growth and survival rate of tilapia was obtained at a dose of 5%, 4.27g and 65%, respectively, while the lowest was in the treatment without probiotics, namely 3.27g and 48.33%. Based on the results of the study, it is recommended that 5% GDM probiotic supplementation in tilapia rearing containers is recommended.

Growth performance of Tilapia (Oreochromis niloticus) cultivated in water from ex-sand pit lakes by phytoremediation treatments

Utilization of ex-sand pit lakes for aquaculture is difficult due to low water quality and high concentrations of iron (Fe). Phytoremediation using aquatic plants has been proven to be effective in reducing Fe in waters. This study aims to determine the growth, feed conversion efficiency and survival rate of tilapia (Oreochromis niloticus) cultured with ex-sand mining water media with phytoremediation treatment. Phytoremediation treatment was carried out by Eichhornnia crassipes, Azolla pinnata, and Salvinia molesta. Fish culture experiments were carried out in plastic tarpaulin tanks for 40 days, with ad satiation feeding, three times a day using the commercial feed. The results showed that phytoremediation with aquatic plants had succeeded in reducing Fe to a level suitable for fish culture. Fish culture experiments showed an absolute length growth rate of 0.09-0.18 cm/day and an absolute weight growth rate of 0.11-0.16 g/day. The feed conversion ratio was 1.18-1.40 and the survival rate was 98.04-99.08%. The survival rate of tilapia is high, the feed conversion ratio is medium and growth is low. The high environmental temperature and the decrease in water quality due to the absence of water changes and aeration are suspected of causing the low growth of fish. Therefore, further research with water change and aeration experiments and the use of other species of fish is needed to follow up the results of this study.

Growth evaluation of Oreochromis niloticus fed different concentrations of choline and methionine

A 12-week research was conducted to determine the effects of choline and methionine supplementation on the growth performance of Nile tilapia (Oreochromis niloticus). Three diets, P2-P4 with 0.04; 0.08; 0.12 % of choline; P6-P8 with same levels choline plus methionine (0.15 %); a diet with only 0.15 % methionine (P5); and control without any supplementation (P1) were fed to tilapia (initial weight ±21.05 g) for 12 weeks. Final weight (FW), Body Weight Gain (BWG), Average Daily Gain (ADG), Specific Growth Rate (SGR), and Protein Efficiency Ratio (PER), Feed Efficiency (FE), Feed Intake (FI), Feed Conversion Rate (FCR), Survival Rate (SR), crude protein and lipid of fish fed various levels of choline and methionine were also measured. The results showed that tilapia fed 0.04 % choline (P2) had significantly better growth parameters and feed efficiency than other groups. Meanwhile, SR of tilapia was not affected by any supplementation of choline and methionine. The tilapia fed 0.08% choline (P3) showed the highest crude protein (52.50 ± 0.98 %) in the carcass proximate but low lipid (19.03 ± 0.10 %). This finding demonstrated the benefits of choline (0.04-0.08 %) supplementation in the tilapia diet in term of growth and carcass proximate.
