 in Lagos lagoon, Nigeria&description=Studies on some aspects of biology of the pink shrimp Penaeus notialis were analysed. 400 specimens of this shrimps, P. notialis were collected from Lagos Lagoon between February and May 2012, and examined with particular reference to size composition, growth pattern, distribution, sex, food and feeding habits. The mean and standard deviation of carapace length ranged from 2.583 ± 0.792 while the mean and standard deviation of total length and total weight ranged from 8.898 ± 1.042 and 4.237 ± 1.775 respectively. The shrimps exhibited a negative allometric growth for length-weight relationship. Condition factor (K) of the shrimp ranged from 0.51 to 0.69 and from 0.27 to 0.59 (male/female) respectively. Sex ratio obtained was 1:0.27. The food and feeding habit of P. notialis from the Lagos Lagoon showed that it fed majorly on crustaceans, diatoms, filamentous algae and plant materials. It was observed that filamentous algae, plankton, crustaceans and other plant materials were its most preferred food.&picture=http://www.aascit.org/aascit/decorators/img/journal/923.jpg)
