Estimation of population parameters of anchovy, Engraulis encrasicolus L. 1758, at 2004-2005 fishing season in The Middle Black Sea, using length frequency analysis methods

Abstract

This investigation was carried out to determine age, growth and mortality of 1245 anchovy, Engraulis encrasicolus L. 1758, in the Black Sea between November 2004 and May 2005. Growth
parameters were estimated after determining the chorts by the “Bhattacharya” method. 0-3 ages groups with mean lengths of 7.90±0.05, 9.91±0.04, 11.66±0.02 and 13.86±0.03 cm were obtained. The sex ratio was 57% females and 43% males in the stock. The determined minimum and maximum length were 6.5 cm and 15.2 cm, weight were 0.98 g and 20.8 g, respectively. Condition factor, length-weight and age-length relationship for overal, female and male were CF = 0.616±0.002, CF = 0.612±0.003, CF = 0.624±0.003, W= 0.0066L2.9669 (r= 0.96), W= 0.0119L2.7266 (r= 0.93), W= 0.0061L3.0071 (r= 0.96), Lt= 21.17[1-e–0.196(t+2.314)], Lt= 20.42[1-e–0.187(t+2.287)] and Lt= 20.09[1-e–0.191(t+2.419)], respectively. Length-weight and condition factors in male and female were statisticaly significant (p<0.05). Total (Z), natural (M) and fishing (F) mortality rate were Z=1.85 year-1, M = 0.34 year-1 and F = 1.51 year-1, respectively. The exploitation rates (E) of 0.82 indicate that the population was being heavily exploited.

Abstract

Bu araştırmada, 2004 Kasım – 2005 Mayıs tarihleri arasında Karadeniz’den elde edilen 1245 adet hamsi balığının, Engraulis encrasicolus L. 1758, yaş, büyüme ve ölüm oranının belirlenmesi konuları üzerinde çalışılmıştır. Büyüme parametreleri Bhattacharya yöntemine göre yaş grupları belirlendikten sonra tahmin edilmiştir. İncelenen örneklerin ortalama boyları 7,90±0,05; 9,91±0,04; 11,66±0,02 ve 13,86±0,03 cm olan 0-3 yaş grubundan oluştuğu belirlenmiştir. Populasyonun %57’sini dişi ve %43’ünü erkek bireyler teşkil etmiştir. Boy dağılımı 6,5 - 15,2 cm, ağırlık ise 0,98 - 20,8 g arasında değişim göstermiştir. Kondüsyon faktörü, boy-ağırlık ve yaş-boy ilişkisi genel, dişi ve erkekler için sırasıyla, KF = 0,616±0,002; 0,612±0,003; 0,624±0,003; W= 0,0066L2,9669(r= 0,96); W= 0,0119L2,7266 (r= 0,93) ve W= 0,0061L3,0071 (r= 0,96); L= 21,17[1-e–0,196(t+2,314)], Lt= 20,42[1-e–0,187(t+2,287)] ve Lt= 20,09[1e–0,191(t+2,419)] olarak tespit edilmiştir. Dişi ve erkek balıkların boy ve ağırlıkları ile kondüsyon faktörleri arasındaki istatistiki fark önemli (p
