Fecundity of Chub Mackerel (Scomber japonicus Houttuyn, 1782) in the Aegean Sea

Abstract

This study was carried out in April - June 2014 to determine absolute fecundity (F) of the chub mackerel (Scomber japonicus Houttuyn, 1782) in Saros Bay (Aegean Sea, Turkey). The relations between the absolute fecundity and total length, total weight and age of the chub mackerel females were estimated as F=0.0318TL4.81, F=1573.9TW- 42858 and F=109607A-136129, respectively. This study aims to contribute to the reproductive biology of S. japonicus by reporting the first findings about the absolute fecundity of the species for the Aegean Sea.

Estimation of growth parameters of the Atlantic chub mackerel (Scomber colias Gmelin, 1789) off Gallipoli Peninsula (Northern Aegean Sea, Turkey)

“…Despite its wide distribution range and commercial importance, there are many studies on population structure (Lorenzo and Pajuelo, 1996;Martins et al, 1983;Martins, 1996;Nespereira and Pajuelo, 1996;Kiparissis et al, 2000;Carvalho et al, 2002;Perrotta et al, 2005;Vasconcelos et al, 2011;Velasco et al, 2011;Čikeš Keč and Zorica, 2012;Daley et al, 2019), as a summary. As for Turkish territoral waters, the data on the biology of this species come from Marmara (Tuggaç, 1957) and Black Seas (Atlı, 1960), Dardanelles (Özekinci et al, 2009), Izmir (Sever et al, 2006;Bayhan, 2007) and Saros Bays (Cengiz, 2012;2021). In addition, while Cengiz et al (2013) calculated the determination of hook selectivity for catching the atlantic chub mackerel, Cengiz (2020) reported the maximum size record of species from Northern Aegean Sea.…”
