The bigmouth bass is a ferocious carnivorous fish. In the wild, predation of various species of fish, shrimps, and aquatic insects is the main type. In the domestication process, it is able to change its dietary habits, and artificially formulated feeds are mainly used. Because the big-mouthed quail has similar disability, it is important to pay attention to feeding techniques in different breeding periods to ensure that the breeding efficiency is improved.
First, the broodstock cultivation period
Broodstock breeding is a very important part of artificial reproduction. It directly affects the success or failure of broodstock gonad development and reproduction. The larvae bred by the bigmouth bream have live bait and artificial compound feed. For the wild big-mouthed broodstock, it is difficult to change the short-lived broodstock. Live bait should be used as the main ingredient. Feed oysters, clams, loach, and miscellaneous fish, and properly match the internal organs of livestock and poultry and feed once a week. For artificially cultivated broodstock, specialized broodstock formulated feeds can be used, and the protein content of the feed should reach about 52%. In the broodstock breeding period, it is better to use artificial compound feed and fresh live bait alternately feeding, and the effect is better.
Second, fry cultivation period
The newly hatched fry was completely bred by its own yolk. After 2 days, the yolk gradually began to disappear. When the larvae were able to swim horizontally, they could eat and eat in the pond. Feeds for fry can be cooked with egg yolks or small horns and copepods. The method is: The eggs are cooked, shelled to take the egg yolk wrapped with gauze, squeeze the egg yolk in the water tray, making it the egg yolk particles slurry, Quanchiposa. As the fish grows up, it can be fed with leeches, chironomid larvae, leeches, fly maggots and various small fry, or some silkworm pupa powder, pig blood, artificial seedlings and other feeds. Feeding amount The amount of leftover bait in the pool before the next feeding is appropriate so as to avoid mutual feeding between the fry due to insufficient feeding. Pay attention to the fact that the biological food should be strictly sterilized before it can be used. Wash the biological food into a 3% salt solution or a 0.5ppm potassium permanganate solution for 3 to 5 minutes to prevent pathogens from entering the pool. Patient.
Third, fish breeding period
During the cultivation of fingerlings, the big-mouthed oysters went through the process of switching from eating live bait to eating artificial feed. At the same time, big-mouth oysters were the most serious food for each other. At this time, big-mouthed oysters were required to feed their favorite feed. After the fish species reaches 5cm, they must be fed with artificially prepared transfer feeds. The basic ingredients are fishmeal, silkworm cocoon powder, pig blood meal, yeast powder, pancake meal, wheat, etc., as well as attractant such as fish carp, shrimp, crab and crab. Animal livers, etc. During the 7 to 12 days of the switching process, feeding 2 to 3 times a day, the feeding amount is 15% to 20% of the fish's body weight. When 70% of the fish species can feed artificial compound feed, artificial compound feed can be completely fed twice a day. Compound feed ingredients: crude protein 42% to 48%, crude fat 8% to 10%, sugar 25% to 30%, crude fiber 6% to 8%, plus a certain amount of vitamins and inorganic salts.
Fourth, adult fish feeding period
Adult fish feed is mainly artificial feed, requiring crude protein 36% to 42%, particle diameter 3 ~ 5mm. Under pond culture conditions, fresh live animal feedstuffs can be fed where conditions permit, including various wild fishes, domestic fish seedlings, tilapia larvae, animal viscera, earthworms, fly maggots, snail meat, etc. These feeds are of good quality but limited in quantity and are suitable for small-scale farm farming. General fish feed can be in accordance with the following ratio: fish meal 25%, peanut powder 18%, yeast powder 5%, fish oil 1.1%, corn powder 10.4%, compound amino acids 2%, premix 2.5%, processing should pay attention The raw materials are crushed as much as possible, and the quality of the binder is better so as to ensure that the feed pellets are not loose in the water for about 1 hour in order to improve the feed utilization rate. In the cage culture conditions, because the bigmouth bass is a fish that does not like to go up and catch food, but likes to inhabit around the box and 4 box corners, it is necessary to set up a feed station, usually 10 square meters, and hang it in the box. Within 20 to 30cm from the bottom of the net. When feeding, the feed is sprinkled on the surface of the water above the feed table and swallowed by the big oysters as the feed pellets gradually fall. When the feeding amount is 5~10cm in length, the daily feeding rate is 8% to 10% of the fish's body weight, and the daily injection is 3 to 4 times. When the total length is 10 to 13cm, the daily feeding rate is the weight of the fish. 4% to 6%, daily shot 2~3 times; full length above 23cm, feeding rate can be reduced to 1%~3% of fish weight, daily feeding 1~2 times, the last time every day feeding can be arranged It takes place around 10pm. In the case of breeding large mouth pupa in paddy fields, it is possible to feed wild fish caught in other waters or use cheap, low-value fish as feed. These small fish can also be chopped into meat purees using a meat grinder to mix other plants. The feed is fed by mixing flour into a mixed bait, which is convenient and affordable, and can meet the nutritional needs of large-mouthed small-scale farming. If the paddy field has a large scale of cultivation, it must be fed with artificial compound feed.
