Role of feed handling in fish farms in Abeokuta, Ogun State, Nigeria

This study examined fish health status in relation to fish feed handling. Twelve (12) fish farms were randomly selected for assessment of types of fish farms, sources, disease problems associated with fish feeds as well as mode of operation and age of farms in Abeokuta, Ogun State Nigeria. Structured questionnaires were administered for data collection. The fish farms surveyed were categorized into three (3) main groups: farms with less than five (5) fish rearing tanks as small scale production (16. 7%), farms with more than five but less than 10 fish rearing tanks as medium scale production (75%) and farms with above ten (10) fish rearing tanks as large scale production (8.3%). The operational methods were fingerlings production (25%), grow-out (table-size) production (25%) and those involved in the production of both fingerlings and table-size fish (50%). All the farms surveyed utilized compounded rations with only one farm combining compounded rations with natural food (artemia). All the farms experienced different levels of limitations in sourcing for feeds. The types of diseases identified on the farms were bacterial disease, parasitic disease as well as water pollution problem. As regards the duration of feed storage, feeds stored for three months and above suffered more disease problems with increase in water pollution level and presence of parasitic disease, while feeds stored for less than two (2) months experienced only bacterial disease. In controlling the highlighted diseases, farms with brood stock fish adopted only the effort of elimination of water (l00%), those involved in fingerlings used antibiotics and malachite green (50% and 100% respectively), those involved in the production of table-size fish used antibiotics (50%), while those involved in production of both fingerlings and table-size employed 100% water elimination.
