摘要

背景：本研究对泰米尔纳德邦东南海岸七种虾类在 2022 年 7 月至 2023 年 2 月期间的长度-重量关系和状态因子进行了研究，并估算了决定系数 (r2)。方法对于对虾物种，长度-重量关系显示一些物种具有显著的正系数，其决定系数（r2 大于 0.5），如 Penaeus indicus、Penaeus mergiuensis、Penaeus canaliculatus、Penaeus latisulcatus、Penaeus monodon；一些物种显示负值（r2 大于 0.5），如 Penaeus japonicas 和 Penaeus semisulcatus。结果所有虾类物种的截距（a）都有明显的异质性。生长指数（b）在 0.278 至 2.289 之间变化，且显著偏离了小于 3 的值（p=0.05），这表明所有对虾品种的负异速生长。

Length-weight Relationship and Condition Factors of Seven Penaeus Shrimp Species along the Southeast Coast of Tamil Nadu (Southern India)

Background: The present study of the length-weight relationship and condition factors of seven shrimp species on the southeast coast of Tamil Nadu between July (2022) and February (2023) also estimated the coefficient of determination (r2). Methods: For shrimp species, the length-weight relationship shows some species have significant positive coefficients which have a determination by (r2 greater than 0.5) like Penaeus indicus, Penaeus mergiuensis, Penaeus canaliculatus, Penaeus latisulcatus, Penaeus monodon, some species have shown negative as (r2 greater than 0.5) value like Penaeus japonicas and Penaeus semisulcatus. Result: All shrimp species have heterogeneity evident in intercept (a). The growth exponent (b) varied between 0.278 and 2.289 and it significantly (p=0.05) deviated from the value of less than 3 which denoted negative allometric growth for all Penaeus shrimp species.
