摘要
为了探明近海不同生态类型鱼类隐蔽伪装色的差异,研究了6种中上层鱼类和5种底层鱼类的隐蔽伪装色,结果表明:无论近海中上层鱼类(包括大甲鲹Megalaspis cordyla、斑■Hemiramphus far、五条■Seriola quinqueradiata、竹■鱼Trachurus japonicus、蓝圆鲹Decapterus maruadsi、蓝点马鲛Scomberomorus niphonius)还是近海底层鱼类(海鳗Muraenesox cinereus、斑尾复虾虎鱼Synechogobius ommaturus、带鱼Trichiurus japonicus、单角革鲀Aluterus monoceros、龙头鱼Harpadon nehereus),黑色素细胞和黄色素细胞均为背部多腹部少,差异显著;相比近海底层鱼类,近海中上层鱼类背腹部体色差异更加明显,中上层鱼类黑色素细胞和黄色素细胞差异更大;虹彩细胞在背腹部皮肤中都存在,而近海底层鱼类的腹部主要为虹彩细胞;红色素细胞在近海底层鱼类中很少存在,但在中上层鱼类中较多。上述结果显示,鱼类背部体色的深浅主要与皮肤中黑色素细胞和黄色素细胞的数量有关,腹部体色的形成主要与虹彩细胞的多少有关。
The countershading formed by deep body color of dorsal surface and shallow body color of venteral surface is beneficial to avoid enemies and prey,and is more common in marine fishes.In order to understand the ecological adaptation of the marine bony fishes and the formation of pigment cells in the dorsal and venter surface,six kinds of marine pelagic fishes and five kinds of demersal fishes were collected,respectively.The results show that no matter the marine pelagic fishes(including Megalaspis cordyla,Hemiramphus far,Seriola quinqueradiata,Trachurus japonicus,Decapterus maruadsi,Scomberomorus niphonius)or marine demersal fishes(Muraenesox cinereus,Synechogobius ommaturus,Trichiurus japonicus,Aluterus monoceros,Harpadon nehereus).Both melanocytes and xanthophores are more in dorsal than in venter,and the difference between dorsal and venter is significant.Compared to the offshore demersal fishes,the countershading in these offshore pelagic fishes is more obvious.The iridocystes are present in both the skins of dorsal and venter,in the venter of marine demersal fishes most of pigments are iridocystes.There are few of the erythrophores in the demersal fishes,but more erythrophores can be seen in marine pelagic fishes.In summary,the investigation shows that the countershading mainly depends on the amounts of both melanocytes and xanthophores in the dorsal skin,and the venter color is related to iridocystes in marine bony fishes.
