花(鱼骨)(Hemibarbus macula+us)俗称“麻叉”,是一种典型的底栖性鱼类。食物为昆虫、虾、螺蛳和甲壳浮游动物。生活在江河、湖泊的花鲳最大个体可达40厘米,在池塘中一般为23——30厘米大小。花(鱼骨)鱼鳞粗,生长较快,内脏比重小,群众欢迎,有饲养价值。多品种混合放养是夺取塘鱼高产的重要手段,驯化当地野生品种又是引种驯化培育新的鱼类养殖品种的主要内容。湘湖渔场自1975年开始进行花(鱼骨)鱼的人工繁殖和饲养试验,以期达到增加新的放养品种和提高产量的目的。现将我们所做的一些初步工作报告如后:
Flower (fish bone) (Hemibarbus macula + us), commonly known as “fork”, is a typical species of benthic fish. Food is insects, shrimp, snails and carapace zooplankton. Living in rivers and lakes, the largest individual flowers up to 40 cm, in the pond is generally 23 - 30 cm in size. Flowers (fish bones) thick fish scales, rapid growth, small proportion of internal organs, the masses are welcome, with breeding value. Multi-breed mixed stocking is an important means to capture the high yield of pond fish. Domestication of local wild breeds is also the main content of introduction and domestication of new fish breeds. Xianghu Fishery since 1975 artificial flower and fish breeding experiments, in order to achieve the purpose of increasing the new stocking varieties and increase production. Here are some preliminary reports of our work:
