一、小沟渠的水情和鱼情在我们徐州市一带乡间田野的小沟渠都是人工开挖的,用来浇灌稻田、菜地,洪水季节用来排水。沟渠的宽不过10米,水最深时多在1.5米左右,冬季水深多在1米或七八十厘米左右。在翻水浇地时,一些小鲫鱼随水被翻到小沟渠里,它们在小沟渠里生长产卵。沟渠里长满了各种水草,一些枯草败叶和庄稼的颗粒被雨水冲到沟渠里,水里生长着很多小水虫、浮游生物,食物丰盛,是鲫鱼生活的“天堂”。人们都认为小沟渠里没有鲫鱼,垂钓爱好者从不去光顾,没有人去那里电鱼,没有人用网去那里捕捞,鲫鱼们在那里自由自在地生长着、繁衍着。
First, the small ditch water conditions and fish In our Xuzhou area along the country’s small ditches are artificial excavation, used to irrigate paddy fields, vegetable fields, the flood season for drainage. The width of the ditch, however, is 10 meters wide and 1.5 meters deep in the deepest water. The winter depth is about 1 meter or seventy-eight centimeters. When turning to irrigated land, some small crucian carp turn into small trenches with water and they grow and spawn in small trenches. Ditch covered with a variety of aquatic plants, some dead leaves and crops particles ran into the ditch by the rain, the water is growing a lot of small water insects, plankton, food abundance, is the “paradise ” of the carp life. People think there is no crucian carp in small ditches. Fishing lovers never go there. No one goes there for electric fish. No one catches the net there and the crucians grow freely and multiply there.
