Özet
Bu çalışmada, İskenderun Körfezi'nde kullanılan iki farklı sepet modelinin av verimine etkisinin belirlenmesi amaçlanmıştır. Çalışmada, A Model Sepet (Girişi Kasnakla Desteklenmiş) ve B Model Sepet (Girişi Kasnakla Desteklenmemiş Silindirik Sepet) modelleri kullanılmıştır. Araştırma, İskenderun Körfezi'nin Pirinçlik-Madenli koyunda, 15 Temmuz-15 Kasım 2001 dönemleri arasında yapılmıştır. 124 çalışma günü boyunca her gün 40 sepet denize bırakılmıştır. Çalışma sonunda 11 familyaya ait, 16 tür ve balık ve ekonomik omurgasız tür olmak üzere toplam 1242 adet birey kaydedilmiştir. Toplam canlı kütle 317,73 kg'dır. Sepet modelleri dikkate alınmaksızın avlama çabası % 0,25 ve en yüksek av verimi Ağustos, Eylül ve Ekim aylarında olmuştur. Tüm çalışma için bulunan 0.04 kg hedeflenmeyen türler ve 0,07 kg ıskarta miktarları oldukça düşük bulunmuştur.
The present study aimed to determine the relative catch efficiencies of two different fish traps in iskenderun Bay. Trap model A had an entrance supported by a hoop, whilst the entrance of model B was unsupported. Fieldwork was carried out in Pirinçlik-Madenli Bight (İskenderun Bay) between 15 July and 15 November 2001. Forty basket traps were set each day during the 124-day study period. Overall 1242 individuals, 16 species and 11 families offish and commercial invertebrates were recorded. The total biomass was 317.73 kg. Fishing effort, irrespective of trap models was 0.25% and the highest catch weight was in August, September and October. The amount of by-catch (0.04 kg) and discards (0.07 kg) were quite low.
