Preliminary evaluation of a new fishing pot trap in Lake Kainji, Nigeria
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.
