Length-weight relationship and condition factor of Sardinella fimbriata (Valenciennes, 1847) and Sardinella lemuru (Bleeker, 1853) from the Bay of Bengal, Bangladesh

Abstract

The current study primarily describes the length-weight relationship as well as condition factor of economically lucrative marine fish species; Sardinella fimbriata Valenciennes, 1847 and Sardinella lemuru Bleeker, 1853 of Clupeidae family from the Bay of Bengal, Bangladesh. In total 42 individuals were collected from a fishing vessel on 7th September, 2022. A scale and an electronic balance were used to measure the length and weight. The slopes, b-values of these species were 2.7135 and 2.6745 respectively, indicating the growth was negative allometric. The intercept, a-values were 0.0197 and 0.0248. Moreover, the relative condition factors were 1.0011 and 1.0032, indicating the general well-being. The relative weights were 100.1065 and 100.3205, indicating the availability of foods and habitats. The current study offered the initial information on the length-weight association as well as the condition factor for the effective management of these species.
