The first assessment of the demographics of Lagocephalus inermis, a species associated with pufferfish bites and fishing down the food web in the Arabian Sea, south-west coast of India, was performed based on length structured population dynamics of 1601 individuals caught in commercial fisheries. Analysis revealed that the current level of exploitation is 90% of the predicted exploitation producing maximum relative yield per recruit (E ), suggesting high levels of exploitation with potential for significant negative consequences for trophic cascades.
基于在商业渔业中捕获的1601个个体的体长结构种群动态，对无鳍兔头鲀（一种与河豚咬伤以及印度西南海岸阿拉伯海食物网下行捕捞有关的物种）的种群统计学进行了首次评估。分析表明，当前的开发水平是预测产生最大单位补充量相对产量（E）的开发水平的90%，这表明开发水平很高，可能会对营养级联产生重大负面影响。
