    Description: Seasonality and overlap of diet of Chrysichthys species in Kainji Lake was studied for a period of one year. A total of two hundred and forty five Chrysichthys nigrodigitatus and one hundred and nineteen Chrysichthys auratus longifilis were used during the study. Chrysichthys species food items ranged from plant to animal materials. Seasonal variations of diet showed that plant material dominated the diet of both species in rainy and dry seasons. While zygoptera and Lumbiculus were absent in the diet of Chrysichthys auratus longifilis in rainy season, zygoptera and nematode were absent in dry season. There was significant correlation (p〈 0.01) of the items between the two species. There was also high level of association between their diets, which indicated that both species have similar diet. Lake Kainji is a good environment for the survival of Chrysichthys species.KEYWORDS: Chrysichthys species, overlap, diet, seasonality, Kainji Lake, Nigeria

    Description: Based on personal working relationship with artisan fishers in the southern portion of Lake Kainji, North Western Nigeria, a new fishing pot trap made with polyvinyl chloride pipe material was designed, fabricated and its performance evaluated by comparison with the traditional Malian trap. The aim was to have a fishing pot trap that is long-lasting and be at least as effective as the Malian trap in fish catch. The results of the study revealed the advantages and limitations in the design and mode of operation of each of the trap type and recommended areas of improvement. Data collected on fish diversity, number and weight were subjected to descriptive statistics and Student’s t-test. The results showed that nineteen fish species belonging to ten families were caught. While the same species density index (SDI) of 0.84 was recorded for both traps, there was no significant difference (P〉0.05) in the catch by number and weight of the two traps.

    Description: Fish marketing and distribution in New-Bussa market was studied weekly for three months (August -October, 2005). The result showed that the major fish species common in New-Bussa fish market are Clarias,Citharinus,Mormyrus,Bagrus,Alestes, Synondontis,Lates, Chrysicthyes, Tilapia, Hydrocynus and Clarotes. The business of catching, marketing and distribution of fish is controlled by young men and women of the age bracket of 14-40 years old. Over 15 different ethnic groups from 14 states in Nigeria and Ghana, Chad, Benin Republic, Mali are involved in fish marketing and distribution business in New-Bussa. The indigenous ethnic groups are Gungawa, Busawa, Kambari, and Nupe, they formed 65% of the ethnic groups found in New-Bussa. The remaining ethnic groups are migrants. Women dominated the trading and processing of fish.

    Description: Studies on the mesh size selectivity of multifilament gill net at Fakun village North of Lake Jebba were carried out. Four different sizes (76mm, 101mm, 126mm and 177mm) of multifilament nets were used in the construction of the gill net with hanging ratio 0.5 each. Daily catch from the nets were examined for seven weeks. The fish caught comprised of nine (9) species, belonging to six (6) families. The result of analysis of variance of the number of species caught showed significant difference (P〈0.05) among the different sizes of the gill net. The catch mean weight for each mesh size (76mm, 101mm, 126mm and 177mm), was 266.91, 285.54, 305.10 and 349.02 respectively. Also the relative percentage of number of species caught by each of the mesh size was 39.48% for 76mm, 23.58% for 101mm, 22.44% for 126mm and 14.48% for 177mm, which depicts the selectivity in the catch of the gill nets in this experiment.

    Description: The importance of fishing gear in fishing cannot be over-emphasized; as without it fish cannot be obtained. The method used to catch fish affects the condition in which the product is landed. This means that a bad-catching method would produced bad fish to the consumer. To achieve the goal of self-sufficiency in fish production in Nigeria, there is need to address the lingering problems of fishing gear and craft technology, especially in terms of availability of materials and their cost. The sale and making of fishing gear materials are two areas of fisheries, which are yet to be exploited by the general public as forms of businesses for livelihood. The study is conducted in villages around the lower part of Kainji Lake, towards the dam, including New Bussa. It reveals that only the fishermen themselves are involved in making their own fishing gears while those involved in the selling of fishing gear materials like the sheet netting, ropes, twines, floats, sinkers etc are business men and women who may not have any experience of fishing. Also considered in the study is the art of making fishing crafts like the canoe and gourd. Very few entrepreneurs are involved and they are so skilled that each is specialized in the making of only one kind of craft or gear
