Abstract

Stock assessment indicators of Pagrus caeruloestictus, Pagellus bellotti, Dentex angolensis and Dentex congoensis from Ghana’s coastal waters were estimated between July 2018 and June 2019. Total length measurements of 2489 samples were collected from some selected coastal communities along the Greater Accra region of Ghana and analyzed using FISAT II Tool. The asymptotic length (L∞) for P. caeruleostictus, P. bellottii, D. angolensis and D. congoensis was 39.9 cm, 31.5 cm, 31.5 cm and 28.4 cm, respectively. The growth rate (K) was 0.18 yr-1 for P. caeruleostictus, 0.36 yr-1 for P. bellottii, 0.75 yr-1 for D. angolensis and 0.83 yr-1 for D. congoensis. The current exploitation rate (E) for P. caeruloestictus, P. bellotti, D. angolensis and D. congoensis was above the optimum level of 0.5, indicating that these species are facing high fishing pressure. To ensure sustainable management of the overexploited fish species, the need for relevant management measures such extension of the closed fishing season, reduced fishing effort and others are urgently required.

Abstract

Gana'nın kıyı sularından Pagrus caeruloestictus, Pagellus bellotti, Dentex angolensis ve Dentex congoensis'in stok değerlendirme göstergeleri Temmuz 2018 ile Haziran 2019 arasında tahmin edilmiştir. Gana'nın Greater Accra bölgesi boyunca seçilmiş bazı kıyı topluluklarından 2489 bireyin uzunluk ölçümleri toplanmış ve FISAT II programı kullanılarak analiz edilmiştir. P. caeruleostictus, P. bellottii, D. angolensis ve D. congoensis için asimptotik uzunluk (L∞) sırasıyla 39.9 cm, 31.5 cm, 31.5 cm ve 28.4 cm idi. Büyüme oranı (K) P. caeruleostictus için 0.18 yıl-1, P. bellottii için 0.36 yıl-1, D. angolensis için 0.75 yıl-1 ve D. congoensis için 0.83 yıl-1 idi. P. caeruloestictus, P. bellotti, D. angolensis ve D. congoensis için mevcut yararlanma oranı (E), bu türlerin yüksek avcılık baskısıyla karşı karşıya olduğunu gösteren optimum seviye olan 0,5'in üzerindeydi. Aşırı avlanan balık türlerinin sürdürülebilir yönetimini sağlamak için, kapalı balıkçılık sezonunun uzatılması, avlanma çabalarının azaltılması ve benzeri yönetim önlemlerine acilen ihtiyaç duyulmaktadır.
