Width-weight relationship and condition factor of Ucides cordatus (Crustacea, Decapoda, Ucididae) at tropical mangroves of Northeast Brazil

Abstract: ABSTRACT. The present contribution aims at evaluating the carapace width vs. humid weight relationship and the condition factor of Ucides cordatus (Linnaeus, 1763), in the mangrove forests of the Ariquindá and Mamucabas rivers, state of Pernambuco, Brazil. These two close areas present similar characteristics of vegetation and substrate, but exhibit different degrees of environmental conservation: the Ariquindá River is the preserved area, considered one of the last non-polluted of Pernambuco, while the Mamuca… Show more

“…Living in food-rich habitats is especially important for females of carideans prawns that present larger size than males, which is the case for M. jelskii. In this case, females need a significant food supply to maintain their growth rate (Howard & Lowe, 1984) and the high energetic demand of ovary maturation after sexual maturity, spawning and incubation of eggs (Sastry, 1983;Pinheiro & Taddei, 2005;Hartnoll, 2006;Araújo et al, 2012;Lira et al, 2012). These biological features could explain the higher abundance of non-ovigerous adult females in M1.…”
