Effects of short‐term temperature changes on the physiology, biochemistry and feeding behaviour of the juvenile yellow seahorse— Hippopotamus kuda Bleeker

Abstract

Seahorse is an important high-value marine fish, which has a huge trade volume in traditional Chinese medicine (TCMs), marine aquarium and souvenir market (Job et al., 2002;Lin et al., 2012).At present, there are 54 known species of seahorse, mainly distributed in tropical and temperate oceans between 50°N and 50°S (Vincent, 2010). Among them, Hippocampus kuda Bleeker is mainly distributed in the Indian Pacific coast (Lourie et al., 2004;LePage et al., 2014).

The effects of environmental changes on the endocrine regulation of feeding in fishes

“…In most cases, fishes placed at higher temperature have higher expression levels of orexigenic factors and lower levels of appetite inhibitors. Examples are lower brain expression levels of POMC in clown anemonefish [29]; higher expression levels of NPY and lower expression levels of CCK in tambaqui brain [31]; higher brain expression of orexin, and lower brain CART and intestinal CCK, PYY in goldfish [33], and lower intestine PYY expression in seahorse Hippocampus kuda [36]. However, this is not always the case.…”
