Shell dimension relationship to soft tissue weight in the fisheries management of soft bottom bivalve Acra senilis (l) from southeastern Nigerian mangals. – I. Ewa – Oboho, N. J. Abby-Kalio and E. I. Oboho
Morphometric relationship of shell length, width and height and living space (volume) as growth estimators were evaluated for Acra Senilis (L) in south eastern Nigeria. When applied to live weight, each parameter proved a good estimator (r2 values 78 to 85%). This was not the case with soft tissue weight (wet, dry or ash-free-dry weight) as each parameter was not reliable in predicting its growth (r2 values 15 to 35%). Significant differences were observed in the b value for shell volume to weight relationship of bivalves collected during the dry season (Nov – Feb) and those of wet season (April to July).
