Understanding the relationships of morphometric and biometric characters of a species allows the prediction of one trait from the other and generate a measure of relative condition. These relationships were studied for the Distant scallop Bratechlamys vexillum (Reeve 1853) in Asid Gulf. Representative samples collected during the dry season (May 2018 n 99) and wet season (September 2018 n 100) were used to analyse these relationships through models of simple linear and power regression analyses revealing allometric growth patterns. For both periods it was revealed that shell width (SW) is a slightly better predictor than the height (SH) for total weight (TW) (R 0.90 and 0.92) and the adductor muscle weight (AW) (R 0.78 and 0.80). The strong functional relationship was also observed between TW and AW (R 0.80 and 0.81). The relative condition factors (Kn) were high in both seasons. High meat yields were also observed in May (12.77 ) and September (14.26 ). The significant difference in meat yields (P 0.05) can be a result of the seasonal difference manifested by the dynamics of energy partitioning during gametogenesis and spawning. These biological metrics are vital inputs in analysing mariculture prospects for the resource and a contribution to the scarce information on the biology of the species.

Abstract

Understanding the relationships of morphometric and biometric characters of a species allows the prediction of one trait from the other and generate a measure of relative condition. These relationships were studied for the Distant scallop Bratechlamys vexillum (Reeve 1853) in Asid Gulf. Representative samples collected during the dry season (May 2018 n 99) and wet season (September 2018 n 100) were used to analyse these relationships through models of simple linear and power regression analyses revealing allometric growth patterns. For both periods it was revealed that shell width (SW) is a slightly better predictor than the height (SH) for total weight (TW) (R 0.90 and 0.92) and the adductor muscle weight (AW) (R 0.78 and 0.80). The strong functional relationship was also observed between TW and AW (R 0.80 and 0.81). The relative condition factors (Kn) were high in both seasons. High meat yields were also observed in May (12.77 ) and September (14.26 ). The significant difference in meat yields (P 0.05) can be a result of the seasonal difference manifested by the dynamics of energy partitioning during gametogenesis and spawning. These biological metrics are vital inputs in analysing mariculture prospects for the resource and a contribution to the scarce information on the biology of the species.
