CURVA DE MORTALIDADE DO CAMARÃO-SETE-BARBAS Xiphopenaeus kroyeri (HELLER), DA BAÍA DE SANTOS

Abstract

The purpose of this paper is the determination of the "mortality curve" of the sea bob shrimp population of Baí­a de  Santos (Brasil, 23°S). This population is exploited by the fishing fleet of Santos. We got the following relationship:

where: 

M  ÌÆ’ (Î" t) = .335N ÌÆ’ (t)1.03
M ÌÆ’ (Î" t) = proportional
number of dead individuals in Î" t;
N ÌÆ’(t) = proportional number of individuals in the beginning of Î" t;
Î" t = 2 months.
