Fisheries and Aquaculture Development in Awba-Ofemili: A Fishing Community in Anambra State, Nigeria
This study examines the fisheries and aquaculture development in Awba-Ofemilli, a fishing community in Anambra state. Data collection was through the administration of questionnaires and scheduled interviews. The data collected were analytically expressed in terms of frequencies and percentages. Results obtained from the study showed that 76.67% males engaged in fish farming and processing while 23.33% females are engaged in marketing with the active working ages between 25-40(45%). Also, 56.67% of the respondent practiced fish farming as their primary source of income. The fishing gears used in the community includes, nets, hook and line with a greater percentage of the respondents that is 81.67% using nets. While, 83.33% of the respondents maintained that they make the most catch during the rainy seasons and catches made during this season often satisfy the market demand. However, 85% of the respondents admitted that their customers come from outside the locality. Species mostly demanded by consumers include; the Nile tilapia (Oreochromis niloticus), Trunk fish (Gymnarchus niloticus) and mud catfish (Clarias gariepinus). Fish and fish products are being sold in fresh, dried and smoked form to consumers. However, challenges encountered include; lack of fishing gears, bad roads, lack of power supply and modern storage facilities, lack of proper education and training in this field, flooding and lack of supports and aids from the government. Based on the results obtained from his study, fisherfolks in the community should be properly enlightened by extension officers, and government should make provisions for power supply, enough fishing gears, modern storage facilities, financial aids and support.

CHANGES IN METABOLITES IN THE PLASMA OF BLACK JAW TILAPIA (Sarotherodon melanotheron ) EXPOSED TO DIMETHOATE IN THE LABORATORY
This study evaluated the metabolic activities in Black Jaw Tilapia (Sarotherodon melanotheron) exposed to dimethoate at varied concentrations of 0.00 (control), 0.05, 0.10, 0.15, and 0.20 mg/L in order to determine the amount of metabolic alterations in fish exposed to chemical in aquatic environment. Six water quality indicators were measured during the trial: temperature, pH, salinity, dissolved oxygen, nitrite, and ammonia. A total of 180 of S.melanotheron, with 60 in each of the three categories of fish sizes used in the study: Group 1 consisted of juveniles with a mean length of 12.45cm±1.98SD and a mean weight of 66.23g±3.04SD; Group 2 consisted of sub-adults with a mean length of 15.22cm±3.03SD and a mean weight of 100.34g±11.00SD); and Group 3 consisted of adults with a mean length of 19.04cm±6.09SD and a mean weight of 142.05g±12.54SD. After the experiment, blood samples from the fish were taken, and metabolite profiles were examined in them using normal laboratory techniques. The results of the study demonstrated that urea levels were significantly greater (P<0.05) in the exposed fish compared to control values, although creatinine, total bilirubin, and total protein values were significantly lower (P<0.05) in the exposed fish. In contrast, the young fish that had been exposed to the toxin showed higher signs of these changes. In the future, comparative studies of metabolic stress in aquatic biota from contaminated coastal habitats and efficient bio-monitoring of the aquatic biota may benefit from the baseline data that this work offers.

Investigation of the Composition, Abundance and Distribution of Fish Species in Ebenebe River, Awka, Anambra State, Nigeria
Fish stock assessment is an integral part of the conservation of aquatic biodiversity and a major key for planning, formulation and execution of fisheries policies and programmes especially in the artisanal sector. of fisheries. The rapidly declining catch from fish landing is a possible indication that the fish yields of most Nigerian inland waters are generally low for causes that may range from inadequate management of fisheries to degradation of water bodies. Fish fauna of Ebenebe River in Awka, Anambra State was investigated in the present study. A total of 1086 fishes were obtained from fishermen within three months, covering 6 families and 12 species with the cichlidae having the highest dominance of 41.06%, followed by the Alestidae (16.06%) and Notopteridae 16.06%). However the dominant fish species observed during the study was Chromiditilapia guntheri (23.7%); Papyrocranus afer (14.3%) and Thysimichromia ansorgii(11.8%).The least abundance fish species were Synodontis filamentous (4.7%), Synodontis ngirita (2.6%) and Brycinus macrolepidotus (2.1%). Conservation policies are urgently needed to protect some species from going into extinction.
