Age, growth, mortality and condition index of an unexploited Ruditapes decussatus population from El Mellah lagoon Algeria
Abstract
Between May 2016 and April 2017, Ruditapes decussatus (Linnaeus, 1758) population from El Mellah lagoon was investigated to collect information about several biological parameters before it upcoming re-operating after 13 years of discontinued exploitation. Total length ranged from 22.15 to 62.53 mm, while weight varied between 2.16 and 46.83g. The allometric relationships between body sizes and length were determined; the length-weight one indicated an isometric growth and expressed as TW = 0.0002 SL2.9853. The age was ranged from the first to the sixth, individuals 2 to 4 years old dominated the population; von Bertalanffy growth parameters were undertaken using the software recommended by FAO (FISAT II, VONBIT for Excel) and estimated to K=0.38 year-1 and L∞= 63.924 mm. The longevity (tmax), the growth performance index (Φ′) and mortality rate (Z) were 7.81 years, 3.61 and 0.65 year-1, respectively. Condition Index was monthly determined for this population as a tool to identify optimal and sustainable harvesting periods which correspond to the period between October and January.
