The reservoir cages do not feed the ecological culture of the bait, and it is a farming method that directly utilizes the reservoir's natural bait for grazing-type extensive and thin raising to produce pollution-free quality Fish. In general, a cage can produce 100 kilograms to 150 kilograms, such as white peony, with a net profit of 300 yuan to 600 yuan.
Before preparations for stocking, we chose lee, Xiangyang, and the bays and rivers that were filled with Xi River water as breeding waters. The net cages are made of polyethylene knot nets with a length, width and height of 3 meters and a hexahedral closed cage with a lid, with a screen size of 3 cm to 4 cm. The cage bracket is made of four bamboos with a length of 3.5 meters and a tail diameter of more than 4 centimeters. The cage can be fixed by anchorage. Each 10 cages are a group consisting of 2 polyethylene steel ropes with a diameter of 2 cm and are ligated along the two sides of the cage in series. The distance between the box and the box is 1 meter, each row is 6 meters apart, and anchors are used at both ends. The rope is straightened and tightened. Each iron anchor weighs 10 kilograms. The anchor rope is 3 cm in diameter and 2.5 times longer than the water depth; or it can be fixed by cable fixation. The rope is made of a 4 cm diameter polyethylene rope, straddling the water surface, stretched and tightened and fixed on the two shores. The two cables are a group of 3.5 meters apart. The cages are fixed in the middle and the cage spacing is 3 meters. The distance between the two groups is 6 meters. The cages are launched 1 week before the fish species are put into the tank. Arranged in "product" shape or plum shape, according to the distribution of cage area and water area 1:100 ratio.
The fry stocking is mainly for flower buds and white storks. The ratio is 8:2, and they are stocked with carp and tilapia. Each of the 20 to 25 fish species weighing 50 grams or more is released. Before the fish is stocked, apply a concentration of 40 g/L to 50 g/L of salt water and sterilize it by bathing for 5 minutes to 10 minutes.
Daily management Clear the garbage in the pool and keep the water in the pool clean. Adjust the tightness of the cable and anchor rope so that the cage is fully deployed. Clean the cage every 15 days to 20 days. When cleaning, lift the netcloth off the water and use a bamboo strip or brush it with a nylon brush.
