ABSTRACT The aim of this study was to determine: (1) salinity that maximizes arm regeneration in the starfish Luidia clathrata; and (2) if low food consumption or low salinity is the cause of the reduced rate of arm regeneration seen at low salinities.. An estimated salinity of 33 g kg−1 produced maximum regeneration of two arms in L. clathrata. This salinity is typically greater than that found in bays that are the usual habitat for the species. Equivalent food consumption by L. clathrata in salinities of 20 g kg−1 and 30 g kg−1 resulted in greater regeneration in salinity of 30 g kg−1, suggesting lower food consumption at low salinities is not the primary reason for lower regeneration. Higher food consumption compared to lower food consumption, both tested in salinity of 30 g kg−1, did not increase regeneration, but resulted in more storage of energy in the pyloric caeca.

盐度和摄食对海星 Luidia clathrata 手臂再生的影响 (Say, 1825) (Echinodermata: Asteroidea)

摘要 本研究的目的是确定：（1）使海星 Luidia clathrata 手臂再生最大化的盐度；(2) 如果低食物消耗或低盐度是在低盐度下观察到的手臂再生率降低的原因。估计 33 g kg-1 的盐度在 L. clathrata 中产生了两个手臂的最大再生。这种盐度通常高于该物种通常栖息地的海湾。L. clathrata 在 20 g kg−1 和 30 g kg−1 盐度下的等效食物消耗导致盐度为 30 g kg−1 时的再生更大，这表明低盐度下的食物消耗量较低并不是再生较低的主要原因。与较低的食物消耗相比，较高的食物消耗，在 30 g kg−1 的盐度下测试，都没有增加再生，
