Biology of the deep water pink shrimp Parapenaeus longirostris (Lucas, 1846) (Crustacea, Decapoda) on the Montenegrin shelf

Population dynamics and stock assessment of deep water rose shrimp Parapenaeus longirostris (Lucas, 1846) from the Mediterranean Coast of Morocco

“…The value of b obtained is below 3 indicating a decrease in growth rate in relation to length. This negative allometry observed corroborates the reports of other authors from the Mediterranean (Levi et al, 1995;García-Rondríguez et al, 2009;Guijarro et al, 2009;Markovic, 2012). Jayachandran and Joseph (1988) opined that weight in case of most of the crustaceans is close to the cube of length.…”

“…The average landings was around 500 t in 2009, 2011, 2012 and 2013, which then declined to nearly 50% during the period from 2014 to 2016 (INRH, 2017). Owing to its commercial importance, a number of studies concerning biology and fishery of P. longirostris, were undertaken from different seas around the world (Yahiaoui et al, 1986;Ribeiro-Cascalhoand Arrobas 1987;Ardizzone et al, 1990;Levi et al, 1995;Sobrino 1998;D'Onghia et al, 1998;Abello et al, 2002;Zengin et al, 2004;Ragonese et al, 2004;Kasalica 2005;Manaşirli, 2008;Markovic, 2012;Bekadja et al, 2014). However, there are no biological studies on the species available from the Mediterranean coast of Morocco, inspite of its commercial importance in the region.…”
