Abstract :
The population parameters of three Carangidae species from the marine waters of Ghana were examined between July 2018 and June 2019. Length and weight measurement of 1020 samples were collected from some selected coastal communities along the Greater Accra region of Ghana and analyzed using TropFish R. The asymptotic length (L∞) for C. crysos, C. hippos, and T. trecae was 37.6 cm, 35.3 cm and 26.1 cm respectively. The growth rate (K) was 0.41, 0.44, and 0.75 yr^-1 for C. crysos, C. hippos, and T. trecae respectively. The exploitation rate (E) estimate revealed overexploitation for C. crysos, and T. trecae (E 0.5) while C. hippos was underexploited (E 0.5). The findings of YPR analysis proved that the Ghanaian stock of these fish species is in a steady-state with the current exploitation rate lower than the exploitation rate at maximum sustainable yield (Emsy).
