Pasif av araçları ile avcılıkta balık davranışları

Balıkçılık faaliyetlerinde kullanılan av aracı ile balık davranışları arasındaki ilişki önemli bir konu olarak hemen hemen tüm dünyaya yayılmaktadır. Yakın gelecekte davranış konusundaki ilerlemeler dünya balıkçılık sektörünü pozitif yönde etkileyecektir. Ülkemiz dahil tüm dünyada küçük balıkçı teknelerinde solungaç ağları, paraketa ve sepet gibi pasif av araçları kullanılmaktadır. Bu nedenle pasif av araçları ile yapılan balıkçılıkta stoku yakından ilgilendiren boy ve tür seçiciliği ile balıkçıyı ilgilendiren av verimi, iş gücü, maliyet ve kazanç konuları ön plana çıkmaktadır. Belirtilen nedenlerden dolayı avlanılacak su ürünlerinin davranışları dikkate alınarak uygun av araçlarının seçilmesi ve dizayn edilmesi yoluyla hem daha verimli bir avcılık yapmak hem de bazı türlerin stoklarını korumak mümkün olabilmektedir.

Fish behaviour at fisheries by passive fishing gears

As an important subject, relation between fish behaviour and fishing gear use at fisheries activity almost separate worldwide. Near future world fisheries sector has effected to positive direction by advance on behaviour subject. Passive fishing gears as gillnets long line and pots used at small fisheries boats inside our country in whole world. As this reason is important catch efficiency, labour power, cost and benefit matters interest for fishermen with length and species selectivity closely interest for stock at fisheries by passive fishing gears. Consequently providing both more effect catch and protect stocks of some species by choose and design of appropriate fishing gears take into consideration behaviour of aqua products will caught.
