Abstract
This is the first attempt to study the population characteristics and growth of the Lesspsian migrant scallop Mimachlamys sanguinea (Family: Pectinidae) from the expansion channel of the Suez Canal. The growth of M. sanguinea was considered by revealing the increasing growth rate of one body parameter to the other. The relationships between shell length and different body weight parameters indicated a negative allometric growth, except shell weight. Monthly variations in three condition indices were investigated during the study period. The highest values were during winter and early spring months, reaching the maximum in March 2022 for CI1, CI2 and CI3 (48.27, 73.84 and 7.57, respectively). The population characteristics of M. sanguinea were studied depending on the length frequency analysis. The von Bertalanffy growth parameters; asymptotic length (L∞) and growth coefficient (K) were 91.93 mm and 0.71, respectively. The theoretical maximum age (Tmax) was 4.22. The growth performance index (φ/) was valued as 3.778. Total mortality (Z), fishing mortality (F), and natural mortality (M) were calculated. The estimated exploitation rate was 0.425, indicating that it is not exploited. This study would aid in better fisheries management and would be helpful for the sustainable exploitation of the senatorial scallop in the Suez Canal expansion channel.
