Yields of Protopterus annectens (Owen) from River Rima and Goronyo Dam, Sokoto State
Ninety five (95) specimena of P. Annectens (Owen) were caught from Goronyo Dam (26) and River Rima (69). The result revealed flesh yield of 44.29~c2.52 in August to 49.46~c to 5.68 in October which was not significant in samples from River Rima. The flesh yield from samples in Goronyo Dam ranged from 46-95~c2.43 in June to 54.28~c3.36 in September indicating significant difference between the months. The waste yield also varied significantly in samples from Goronyo Dam 45.72~c3.36 in September to 53.05~c 2.43 in June. However the results indicated non-significance (P>0.05) difference in samples from River Rima with a range of 50.54~c6.68 in October to 55.71~c2.55 in August. Similarly the flesh yields were found to be higher during the dry season than in the rainy season. The sample specimens were found to contain enough flesh thereby creating potentialities to caning industries.
