Abstract

The length-weight relationship and condition factor (CF) of Penaeus notialis from Amadi-Ama Creek, Port Harcourt, Nigeria was studied between May and July 2019. This was to provide some data that could serve as a guide in making managerial decisions on the stock. A total of 200 P.notialis were collected; sampling was done twice in a month from fishers and middlemen at the landing sites. It comprised of 103 males and 97 females. The lengths, weights, and CFs were calculated according to the standard methods. Data were subjected to FAO-ICLARM Stock Assessment Tools (FISATII) and Microsoft Excel. The “b” values were 2.15 (male), 1.95 (female), and 2.12 (combined), respectively. All the “b” values were less than 3 indicating negative allometric growth. The overall monthly Fulton’s condition factor (k) obtained from the study was k=1.183+0.42. This indicated that the shrimps were in good condition during the sampling period.
