Biological traits and population dynamic of Parapenaeus longirostris (Lucas, 1846) in the Marmara Sea, Turkey

Abstract



Parapenaeus longirostris is a valuable resource for the crustacean fisheries in the Marmara Sea, therefore, in this study length-weight relationships, growth, mortality, reproduction, recruitment patterns, the probabilities of capture and per recruit analyses were determined. Total 36288 samples were collected by beam trawl between September 2011 and July 2014 in 229 sampling stations. The total length (TL), body weight (g) and carapace length (CL) values ranged between 34 -175 mm, 0.2 - 28.9 g and 8 - 41 mm, respectively. CL-weight relationship equations were calculated for females, males and combined sexes, respectively, W=0.0023×CL2.5, W=0.0029×CL2.43, W=0.0022×CL2.52. The growth parameters were determined as L=199.5 mm, k=0.47, t0=-0.5 in TL, L=36.8 mm, k=0.37, t0=-0.69 in CL. L25, L50, and L75 values were found to be 15.15 mm, 16.29 mm, 17.44 mm for males and 16.62 mm, 18.07 mm, 19.52 mm for females. The sexual maturity length for females was found 27.3 mm CL and the exploitation rate was found at 0.62 for the whole population.
