All the diets were iso-nitrogenous. One hundred andfifty (150) C. gariepinus juveniles (33 g ~ 35 g) were randomly distributedto five treatments with three replicates each and 5% of their body weightfor 12 weeks. Fish carcass proximate compositions analyzed before andafter feeding with the experimental diets shows that CP and EE differedsignificantly (p<0.05) among the experimental fish and the control, exceptthe percentage CP of the fish fed SPP0% and SPP50% in which there wasno significant difference (p>0.05). Highest MWG of 207.70±25.95 g wasobtained in the fish fed SPP100% followed by 191.30±16.15 g obtained inthe fish fed SPP75%. The least MWG of 149.83±16.01 g was recorded infish fed SPP25%. The highest FCR of 3.61±0.45 g was recorded in the fishfed SPP100%. A steady decrease in FCR was observed with decreasinginclusion levels of SPP meal. However, higher FW, FL, SGR and PERwere observed in the experimental fish as from 50% inclusion levels of theSPP. The cost of feed per kg was reduced and the NP and WG increasedwith increasing levels of SPP and the profitability was enhanced at 100%SPP inclusion level. The results revealed that C. gariepinus juvenile couldtolerate up to 50%, 75% and 100% inclusion levels of SPP.

This study investigated bacteria associated with milt in cultured samples of African catfish- Clarias gariepinus. Catfish broodstock were collected from private Fish Farm in Ogun State, Nigeria. Fish samples were taken to the Microbiology laboratory, Federal University of Agriculture, Abeokuta Ogun State for milt microbial analyses, and amplicon were taken to International Institute of Tropical Agriculture, Ibadan for molecular characterization. Bio-edit was use for importing and mining nucleotide sequences into gene bank. The results revealed that the following bacterial organisms were present in the milt of Clarias gariepinus: Aeromonas caviae, Proteus mirabilis, Serratia rubidaea, Pseudomonas mosselii, Acinetobacter soli and Klebsiella variicola. The Basic Local Alignment Search Tools revealed the percentage similarity ranging from 86- 97.04% and their accession numbers. These bacteria indicated high levels of faecal contamination in the environment. In conclusion, bacteria were found in the milt of cultured catfish and are capable of being pathogenic to humans and may increase the vertical transfer to fry during breeding and rearing stage.

This study was conducted toknow the fillet quality, gut content and condition of Parachanna obscuraand Clarias agboyiensis in Nigeria using Igbokoda river as a referencebecause it is a the major fishing site in the nation. Studies were conductedon the viscera somatic index based on the organ weight and the bodyweight of the fish and the food item consumed by Parachanna obscura andClarias agboyiensis between May to October, 2019 to infer on the filletquality and gut content of P. obscura and C. agboyiensis in the water bodyrespectively. A summary of food items that constituted the diet of Clariasagboyiensis are Baccillariophyta, fish, fat droplets, dinoflagellate, insectand Chlorophyta which constituted the most important food items bothoccurring in all stomachs containing food. The fishes has more muscle thanthe viscera organs which indicate that the weight of the fish before dressingout is higher than the weight of the fish after dressing out. This is suggestiveof a good quality of food fish. There was a significant correlation betweenbody weight and total length of specimens found in this study. Increasesin total length resulted in corresponding increases in body weight. Theresult for the condition factor showed was below the expected or standardvalue (K = 1) which shows this species was not in favorable environmentalcondition. It is therefore necessary to allow phytoplanktons grow well inwater body to increase availability of food items to Parachanna obscuraand Clarias agboyiensis. P. obscura and C. agboyiensis are also good foodfishes of a high fillet quality. They are omnivorous feeders therefore havingpotentials for aquaculture.
