本文探讨了池色和饵料密度对斑点沙鲈鱼幼鱼初次取食的影响。斑点沙鲈鱼是一种在实验室里培养了十年的物种。在第一次进食时，幼虫的眼睛和消化道功能正常，这使得它们可以开始进食。首先，硬骨鱼幼虫的摄食被认为是幼虫养殖的一个重要方面。研究表明，光照强度、饵料密度和饲养池颜色等培养条件影响饵料效率，进而影响幼虫在培养条件下的生长和存活。在之前的一项研究中，研究人员发现斑点沙鲈幼虫是视觉捕食者，较高的光照强度会增加初次进食的发生率和强度。在第一次饲养时提高饲养效率的培养条件有助于提高成活率，降低发育最初几天的饥饿风险。
This article discusses the effects of tank colour and prey density on first feeding of the spotted sand bass Paralabrax maculatofasciatus larvae. The spotted sand bass Paralabrax maculatofasciatus is a species that has been cultured in a laboratory over the past decade. At first feeding, functional eyes and digestive tract are present, which allows the larvae to begin feeding. First feeding of teleost larvae is considered an important aspect of larviculture. It has been shown that culture conditions including light intensity, prey density and colour of the rearing tank affect feeding efficiency and consequently, larval growth and survival under culture conditions. In a previous study, researchers showed that spotted sand bass larvae are visual predators and that higher light intensity increased feeding incidence and intensity at first feeding. Culture conditions that enhance feeding efficiency at first feeding contribute to increased survival rates and reduced risk of starvation during the first days of development.
