The present study investigates the demographic characteristics of economically, ecologically and medicinally important mudskipper species, Pseudapocryptes elongatus (Cuvier, 1816) from Indian Sundarbans, based on data collected over 15 consecutive months. Length-frequency data of 945 individuals collected from the Indian Sundarbans were analyzed using a FAO-ICLARM Stock Assessment Tool. Length–weight relationships analysis showed negative allometric growth in P. elongatus population. Condition factor indicated the well–being of the population in the study area. The von Bertalanffy growth curve showed six growth cohorts, higher growth coefficient (K = 0.62 yr⁻¹) and growth parameter index (Ø′ = 2.48). The elongated mudskipper population can grow faster and achieve a large asymptotic length (L_∞) of 24.15 cm and thus could be a potential candidate for aquaculture in India. There were two recruitments bouts per year. The higher natural mortality rate (M = 1.39 yr⁻¹) than the fishing mortality rate (F = 0.43 yr⁻¹) with exploitation level (E = 0.24) below the optimum level indicates that the state of the stock is sustainable under current harvesting strategy. Present level of harvesting also offers an excellent fishing opportunity for fishers to increase their yield. We therefore suggest the implementation of new harvesting methods to increase the yield. Additionally owing to the rich taste and high nutrient content of P. elongatus it is also important to focus on the aquaculture of this species, particularly in India based on the information provided in present study and the information available from other parts of the world. Present study also has conservation significance as the study species is as an indicator species of the mangrove ecosystem.

本研究基于连续15个月收集的数据，调查了印度桑达班地区具有经济，生态和医学重要性的泥sk物种Pseudapocryptes elongatus（Cuvier，1816）的人口统计学特征。使用FAO-ICLARM库存评估工具分析了从印度Sundarbans收集的945个人的时频数据。身长体重关系分析显示，P。elongatus种群的异形增长为负。条件因素表明研究区域人口的健康状况。von Bertalanffy生长曲线显示六个生长队列，较高的生长系数（K  = 0.62 yr ^-1）和生长参数指数（Ø' = 2.48）。细长弹涂鱼种群可以成长得更快，并实现大渐近长度（大号_∞ 24.15厘米），因此可能是在印度水产养殖的潜在候选。每年有两次招募回合。在剥削水平（E）下，自然死亡率（M  = 1.39 yr ^-1）比捕捞死亡率（F = 0.43 yr ^-1）高= 0.24）低于最佳水平表示当前的收获策略下种群状态是可持续的。当前的收成水平也为渔民增加产量提供了极好的捕捞机会。因此，我们建议实施新的收割方法以增加产量。此外，由于延长对虾的味道和高养分含量，根据本研究提供的信息和世界其他地区的信息，特别是在印度，特别要关注该物种的水产养殖。由于该研究物种是红树林生态系统的指示物种，因此本研究也具有保护意义。
