Trol ağları seçiciliğinin balıkçılık yöntemi açısından değerlendirilmesi

Su ürünleri avcılığının stoklar üzerinde birtakım etkilerinin olması kaçınılmazdır. Ancak, alınacak bazı önlemler, bu etkileri mümkün olan en alt düzeye indirgenmesine olanak sağlayabilir. Trol ağlarında boy seçiciliği genellikle ağ göz açıklığı ile kontrol altında tutulmakla birlikte, günümüzde pek çok değişkenin seçicilik üzerinde etkili olduğu bilinmektedir. Bu değişkenler trol seçiciliğini doğrudan veya dolaylı olarak etkileyebilmektedir. Trol ağlarının dizaynında, operasyonlarında ve trol avcılığının düzenlenmesinde bu değişkenlerin dikkate alınması, denizel balıkçılık kaynaklarımızın korunması ve bu amaçla getirilen yasal düzenlemelerin etkinliğinin arttırılması açısından önem taşımaktadır.

An overwiev of trawl selevtivity by the wievpoint of fisheries management

It's almost inevitable that some effects of fisheries on the fish stocks and fishing grounds. On the other hand, some measures that will be taken may decrease the unwanted / destructive effects to the level as low as possibble. Commonly, trawl selectivity is controlled by mesh size, but recently, it's known that the codend selectivity is under the effect of numerous variables. These variables may affect selectivity directly or indirectly and should be taken into account while designing and operating trawl nets and managing trawl fishery in order to protect living marine resources.
