Gana Kıyısındaki Kırmızı Pandora'nın (Pagellus bellottii Steindachner, 1882) Üreme Biyolojisi ve Yönetime Yönelik Etkileri

Öz

Ocak 2019 ile Aralık 2019 tarihleri arasında Gana kıyılarından ticari avlardan cinsiyet oranı, olgunluk safhaları, yumurtlama dönemi ve ilk eşeysel olgunluk boyunu belirlemek amacıyla toplam 933 Pagellus bellottii örneği elde edilmiştir. Erkek-dişi oranı 1.39:1 idi. İncelenen balık türünün dişi bireyleri için Temmuz ve Mayıs ayları, en yüksek ana yumurtlama aylarıydı Kasım'dan Ocak'a kadar küçük yumurtlama dönemi ve Mart'dan Eylül'e kadar büyük yumurtlama dönemi olmak üzere iki yumurtlama dönemi gözlemlenmiştir. Dişi bireyler erkeklere göre sırasıyla 20 cm ve 20,8 cm, daha erken olgunlaşmıştır. Bu çalışmanın sonuçları, Gana'daki kırmızı pandora'nın mevcut minimum avlanma boyunun revize edilmesine yardımcı olabilir.

Reproductive Biology of Red Pandora (Pagellus bellottii Steindachner, 1882) from the Coast of Ghana and Implications for Management

Öz

A total of 933 samples of Pagellus bellottii were obtained from the coast of Ghana between January and December 2019, from commercial catches to determine the sex ratio, maturity stages, spawning period, and length at first maturity. The male to female ratio was 1.39:1. July and May were the main spawning peaks for female individuals of the assessed fish species. Two spawning periods were observed with a minor spawning period from November to January and major spawning from March to September. Female individuals matured slightly earlier than male individuals at 20 cm and 20.8 cm respectively. The results of this study could help to revise the existing minimum capture size of Red Pandora in Ghana.
