摘要

Fisheries management requires reliable baseline data on growth and condition parameters of exploited stocks. This study assessed the length-weight relationship (LWRs) and Fulton’s condition factor (K) of Exhippolysmata ensirostris (n = 901) and Solenocera crassicornis (n = 849) from Jafrabad, Gujarat (January 2024–December 2024). These two species were chosen for the study, as penaeid shrimps represent an important component of domestic and export fisheries, while non-penaeid shrimps form an important component of dried fish and traditional seafood markets along the Gujarat coast. Total lengths ranged from 3.37 to 10.00 cm with corresponding body weights of 0.12–5.97 g in E. ensirostris, whereas S. crassicornis exhibited total length range of 3.02–9.83 cm with weight varying between 0.12 and 7.92 g. The LWRs of E. ensirostris showed positive allometric growth (b = 3.14), with a strong model fit (r² = 0.89), and the estimated b value differed significantly from isometric growth (t = 3.90, p < 0.05). Similarly, S. crassicornis also exhibited positive allometric growth (b = 3.08), with a high coefficient of determination (r² = 0.95), and a statistically significant deviation from isometry (t = 3.17, p < 0.05). The K peaked during September–October for E. ensirostris and April–May for S. crassicornis, consistent with spawning periods. This study represents the first global report on the LWRs and K of E. ensirostris, based on field samples collected from Gujarat, India. It provides essential baseline data for the management, conservation, and future stock assessment of these commercially important species in the North-western Arabian Sea ecosystem.
