Saros Körfezi’nin (Kuzey Ege Denizi) kıyısal sularında ağ dalyan ile yakalanan balıkların boy-ağırlık ilişkileri

Ağ dalyanlar, Kuzey Ege Denizi'nin Saros Körfezi kıyılarında geleneksel yöntemlere göre balık avlamada kullanılan pasif av araçlarıdır. Bu çalışmanın amacı, Saros Körfezi kıyılarındaki ağ dalyanlardan toplanan çeşitli balık türleri için boy-ağırlık ilişkilerini (LWRs) belirlemektir. 2010 - 2012 yıllarında Nisan ve Ağustos ayları arasında (balık avlama sezonu) dört ağ dalyandan yakalanan balık türlerinde çalışılmıştır. 12 aileye ait toplam 23 balık türünde toplam 2.096 adet birey yakalandı. Büyüme ilişkilerinin (b) ortalama değeri 3,141 ± 0,042 iken, 2,711 – 3,577 arasında değişmiştir. Sadece iki tür (Pomatomus saltatrix ve Mugil cephalus) negatif allometrik iken, diğer balık türlerinden 13 pozitif allometrik ve 8 izometrik olduğu tespit edilmiştir. LWR parametreleri pozitif allometrik ve izometrik balık türleri için anlamlıydı (P

Length-weight relationships of fishes caught by stationary uncovered pound nets in the coastal waters of Saros Bay, North Aegean Sea (Turkey)

Stationary uncovered pound nets are passively fishing gears used for fish catching according to traditional methods in the coastal waters of SarosBay, North Aegean Sea. The purpose of this study was to determine length-weight relations (LWRs) for a wide range of fish species collected from the trapsin the coastal waters of Saros Bay. We are studied in the fish species caught by four traps between April and August (fishing season) in 2010 - 2012. A totalof 23 fish species belonging to 12 families were caught individual 2.096. The mean value of the growth pattern (b) was 3.141±0.042, ranging from 2.711 to3.577. Whereas they were negative allometric only for two species (Pomatomus saltatrix and Mugil cephalus), from other fish species were observed to be13 positive allometric and 8 isometrics. The LWR parameters for the positive allometric and isometric fish species were significant (P
