This study evaluated the effect of exogenous digestive enzymes on the survival, growth performance and morphology of the digestive tract of juveniles of the longsnout seahorse Hippocampus reidi fed exclusively with Artemia and supplemented with five different concentrations of porcine pancreatin (PP) (0, 5, 25, 50 and 75 mg/L from birth until 30 days after release). The results found in the present study clearly show that there was a significant increase in survival and growth as well as substantial changes in the morphology of intestinal villi in seahorses fed exclusively with Artemia supplemented with 75 mg/L PP. Therefore, the use of digestive enzyme supplementation constitutes an important advance for the establishment of a more efficient and practical feeding protocol (exclusive use of Artemia) for juveniles of the longsnout seahorse.

使用卤虫补充外源性消化酶作为唯一的活食，可以延长长尾海马海马幼体在幼鱼养殖期间的存活和生长。

本研究评估上的longsnout海马少年的消化道的存活，生长性能和形态外源消化酶的影响海马reidi专门与供给卤虫和补充有5种不同浓度的猪胰酶（PP）（0,5，从出生到释放后30天分别为25、50和75 mg / L）。在本研究中发现的结果清楚地表明，仅用卤虫病喂养的海马的存活和生长显着增加，肠道绒毛的形态也发生了显着变化补充75 mg / L PP。因此，使用消化酶补充剂为长寿海马的幼鱼建立更有效和实用的喂养方案（卤虫专用）提供了重要的进展。
