| 摘 要： | 丝足鲈(Osphronemus goramy),英文名为Giantgouramy,分类上隶属鲈形目(Perciformes),长丝鲈科(Osphronemidae),原产于东南亚诸国,为东南亚的养殖对象。1998年,我所从越南引进该种鱼,见图1。由于其生长快,食性杂,易饲养,在国内已逐渐成为一个新的养殖对象。其体型奇特,尾鳍鲜红,有一定的观赏价值。因该种鱼引进我国时间不长,有关的研究很少。为了推广养殖该种鱼,有必要全面了解该鱼的形态特征以及其核型。因此本文对于丝足鲈的形态特征及核型进行了详细观察及研究。

| Abstract: | This paper reports the kayotype and morphological character of Osphronemus goramy . Osphronemus goramy is characterized by its long silk-like ventral fin. There are two suprabranchial organs in its head. Its gas bladder belongs to physoclistaus and it extends to caudal peduncle. The verge of placoid scale is black and its body black net-like. Its stomach is strong and the intestine has a long length with two pyloric caecas. The lateral line scale formula is 3638(7/15 - 16). The number of diploid chromosome is 2n = 48 and the karyotype formula is 2sm + 46t,NF = 50. |
