Diversity and abundance of cichlids in Ikere Gorge Reservoir, Iseyin, Oyo State, Nigeria

Cichlids are highly abundant and commercially important fish in freshwater ecosystems in Nigeria. This study examined the diversity and abundance of cichlids in Ikere Gorge Reservoir. Four fishing villages were randomly selected from 12 fishing villages in Ikere Gorge Reservoir as sampling sites. Cichlids were sampled randomly and examined from fishermen catch in each selected fishing village; were identified with appropriate keys; the weight and abundance of the catches were recorded. The data obtained was subjected to descriptive statistical analysis using SPSS (Version 20.0) software to determine the abundance of fish species. Fish species diversity was carried out by using Palaeontological Statistics (PAST). Eight species of cichlids were sampled in Ikere Gorge but Sarotherodon galilaeus was the most abundant species while the least abundant species was Pelmatolapia mariae. It was observed that, cichlids were abundant in rainy season than in the dry season. Likewise, cichlids were abundant in Ikere-gorge reservoir but they have low diversity. This may be as a result of unsustainable fishing pressure and deforestation of riparian forest and sedimentation in Ikere-gorge reservoir. Therefore, to maintain sustainable fishing activities and improve cichlids population in Ikeregorge reservoir, unsustainable activities in and around Ikere Gorge reservoir should be put under control.

Haematology, serum biochemistry and condition factor of the African snakehead fish, Parachanna obscura from Nigeria’s hydrologic areas

Rapid change in the conservation status of Parachanna obscura from least concerned to endangered species raises concerns over the health of the natural populations of this stock in Nigeria. This study therefore investigated the haematology, serum biochemistry and condition factor of P. obscura from Nigeria's freshwater environment to assess their wellbeing. All eight hydologic areas in Nigeria were purposively selected while one river in each of the basins was randomly chosen for sampling of P. obscura. These randomly selected rivers were from Anambra (Niger South), Imo (Eastern south) , Ibbi (Upper Benue), Kaduna (Niger Central), Katsina Ala (Lower Benue), Hadejia (Lake Chad), Ogun (Western Littoral) , and Sokoto (Niger North) rivers. Fish samples were collected quaterly for a year from fishermen's catch. One-way ANOVA and Duncan's Multiple Range Test were employed for data analysis. Percentage parked cell volume, lymphocytes, neutrophil and monocytes as well as haemoglobin and red blood cells were not significantly different (p>0.05) across populations. However, other haematologic parameters differed significantly among the populations. Samples from river Ibbi had significantly higher levels of glucose (47.75±3.22 mg/dL), aspartate aminotransferase (42.25±2.72 U/L), alanine aminotransferase (33.25±2.14 U/L) and blood urea nitrogen (1.91±0.31 mg/dL). Condition factors averaged 0.81±0.01. The present study showed that measured haematologic and serum biochemistry parameters as well as the condition factor were within normal reference values for P. obscura or similar tropical fish species reference values. Therefore, other causes of the decline in population of this species in Nigeria should be investigated.
 Keywords: Parachanna obscura, Nigeria's freshwater environment, Population decline, Endangered tropical fish species.

Fish catches diversity of the glass eel fishery in Cikaso and Cimandiri estuaries, Sukabumi, Indonesia

Cikaso and Cimandiri estuaries are well known as the central area of glass eel fisheries in Sukabumi Regency. Local fishermen catch glass eels using two main fishing gears, namely traps and lift nets. Although both fishing gears' target operation is glass eels, many other fish species are also caught as bycatch. The present study aimed to identify glass eels and bycatch ichthyofauna in glass eel fisheries of the Cikaso and Cimandiri estuaries, Sukabumi. The research was carried out monthly from November 2020 to January 2021. Glass eels fishing gears collected a total of 21 fish species belonging to 15 families in both estuaries. According to the percentage ano-dorsal length measurement to total length (AD/TL), 3 species of glass eel were identified, i.e. Anguilla bicolor bicolor, A. nebulosa, and A. marmorata. These three species were the most abundant fish catches in both estuaries. More than 18 bycatch ichthyofauna were recorded and most of them are economically important fish, such as Ambassidae, Eleotridae, Engraulidae, Gobiidae, and Polinemidae. To sustain fishery management, the recording bycatch from glass eel fishery in the Cikaso and Cimandiri estuaries is necessary to be done regularly because they contribute to fishing mortality.

Estimation of small-scale fisheries production development trend in Nepal

Nepal is a landlocked country with enormous natural diversity ranges from the world's highest peak, Mt. Everest to the Tarai area. Nepalese aquaculture is still in its early stages, and fish production is still insufficient in comparison to global levels. Fish is a popular cuisine in Nepal, and it is enjoyed by people of all ages, genders, and religions. The total national fish production is currently 77,000 m.t., with 28 percent coming from catch fisheries and 72 percent from aquaculture. Aquaculture and open-water capture fisheries account for around 2% of agricultural gross domestic product; this little share of the fisheries sector is promising, with an annual growth rate of 8–9%. Total fisheries production in Nepal was reported at 81070 metric tons in 2018, according to the World Bank assortment of development indicators, compiled from officially recognized bases. Small-scale fishermen's catch production and secondary data in Nepal's Chitwan District, Bagmati Province, from 2010 to 2019. Regression estimates model and multivariate regression analysis of time series data, the Cobb-Douglas production function equation rational technique is applied. Changes in the number of fish caught have an impact on the home economics and spending. The length of the river, outboard engine power, and regional differences in area were found to have a positive impact on small-scale fishermen's catch production, whereas gasoline, schooling, and family dependents had a negative impact, though fishing gear, kerosene, and fishermen's age had no considerable impact.

Reproduction of White-Spotted Rabbitfish (<i>Siganus canaliculatus</i> Park, 1797) in the Waters of the Buntal Island, Kotania Bay, West Seram-Mollucas

White-Spotted Rabbitfish (Siganus canaliculatus Park, 1797) are herbivorous fish that are associated with seagrass habitat and are widely distributed in mangrove and coral reef habitats. The waters of the Buntal Island – Kotania Bau have an ecosystem of seagrass medows, mangroves and coral reefs, with the association of S. canaliculatus as one of the target catch of fishermen. The purpose was study to analyze the biological aspects of S. canaliculatus, including: sex ratio, size of first maturity, and fecundity. The research was conducted from October 2015 until January 2016 in the waters of Buntal Island, Kotania Bay. Fish samples were collected from fishermen's catch using bottom gill nets and Set net. Each fish sample was dissected for sex determination and gonad maturity level. The analysis is used to see the relationship between body length and weight and fecundity. The results showed that 167 fish and 149 female fish. The ratio of male and female was balanced, namely 52.85%: 47.15% or 1.1: 1 (X2count 4.13 <X2table 11.34). The size of first maturity of female is 14.98 cm (14.5 - 15.5 cm) smaller than the male 18.9 cm (18.8 - 19.1 cm). The high potential of S. canaliclulatus based on the Fecundity obtained was in the range of 524,000 - 1,286,359 eggs. There is a positive relationship between body length and fecundity, indicating that the value of Fecundity increases with body size. To support its sustainable use in the wild, it is necessary to regulate the size of S. canaliculatus that can be harvest at a body length of > 15 cm TL, to provide opportunities for spawning and support population growth before exploitation, thus supporting responsible and sustainable fisheries.

Variability of Sea Water Temperature and Its Implication on Cakalang Fish Capture (Katsuwonus pelamis L) in Manokwari Waters, West Papua

The presence of skipjack fish resources in a fishing area is related to the suitability of the environmental conditions of the waters. This study aims to examine the relationship of sea surface temperature (SPL) to skipjack catches and the characteristics of skipjack catches in Manokwari waters. Data, both catch data and sea surface temperature data, are collected through field surveys by following fishing operations. Furthermore, the data were analyzed descriptively using graphs and mathematically like von Bertalanffy's growth model. The results of this study found that the very small variability of SPL could not explain the variation in the volume of fishermen's catches in Manokwari waters. However, a high SST during the May - August 2013 period is thought to affect the size of the skipjack caught, where the average size of the fish caught inhabited areas near sea level. In addition, the growth of skipjack fish in Manokwari waters is relatively fast with a growth coefficient of 0.42 per year1 and natural mortality between 0.79 per year and 0.81 per year.

Work Becomes Obligation for The Family: Analysis of Work-Family Balance on Fishermen's Wife

This study aims to reveal the experiences of fishermen's wives working in balancing the dual roles of work and family, as well as the factors that can influence it. This study uses a qualitative method with a phenomenological approach. The data analysis technique in this research uses the Interpretative Phenomenological Analysis (IPA) technique. The researcher managed to conclude that there were five main themes including; a picture of life at work, the dynamics of life in the family, a picture of life undergoing multiple roles, the factors that influence the dual role of fishermen's wives and exploration of achieving balance in playing multiple roles. The role of being a housewife in a family and working to help the family economy begins when fishermen's wives choose to work after marriage. The encouragement of fishermen's wives to keep working after marriage is due to uncertain family income. This is also because their husband's catch depends on the season. Erratic season affects the fishermen's catch. One of the encouragement of fishermen's wives to work is to actualize their potential and abilities and to meet family needs
