Pond pond quail breeding natural breeding technology
Tanggu commonly known as tigerhead sharks and pomfret, its meat is delicate and delicious, and is deeply favored by consumers. As the demand for Tanggu grows in the market, seed supply will become the main factor restricting scale farming. In order to solve the source of the seedlings in Tanggu, we conducted the planned natural breeding of the pond ponds and their cultivation of productive tests from 2003 to 2004. The main techniques are now described as follows:
1 The fry is intended to reproduce naturally
1.1 Sources of broodstock One is to purchase from the market or to harvest healthy physiques from natural waters, disease-free and injury-free 2 to 3 year-old individuals, and transport them for storage; second is to cultivate broodstock in ponds and acquire natural fish species for intensive cultivation. Individuals as parents require 2-3 years of age, 70 g for females and 80 g for males.
1.2 Identification of male and female Tongqin male and female similar, from the shape is difficult to identify, but the reproductive season easier to distinguish, the male individual is slightly larger than the female, the abdomen is small, while the female abdomen is inflated, soft; female anal fin is not or very few There are silver-gray spots, dense spots on the anal fins of the males and around the drain holes.
1.3 Breeding pond The breeding pond area is 1000-1500 m2, and the water depth is 0.8-1.5 m. The bottom of the pool is preferably sandy loam, with less silt, and complete water injection and drainage facilities. Disinfect with quicklime before placing into the broodstock. Fill water 50-60 cm.
1.4 Bred by broodstock The broodstock collected were bathed with 3% saline for 10-15 minutes and placed in breeding ponds. The stocking volume was 3-4 tails/m2, and the male-female ratio was 1:1.2. When the water temperature reaches 14 °C or more, it begins to feed and feeds mainly small fish, shrimp, minced pork, etc. From April, flush every 2 to 3 days to promote gonadal development.
1.5 Induction of spawning When the water temperature is stable at 18 to 25 °C (in the spring when rape buds are in full bloom, it is the season of pond fish spawning), and "triple tiles", large-caliber bamboo tubes, clam shells, and gray plastic tubes are arranged. Such as the production of ovaries, regular flushing stimulation, so that they naturally spawn, generally 12 hours after the female and male fish began to pair, spawn, fertilization.
1.6 Naturally hatched males have an egg-protecting habit. Checking the ovaries, you can see that males use the pectoral fins to constantly fan and drive the water. This is conducive to embryonic development. Before the fertilized eggs begin to hatch to the membrane, the ovaries are soaked every 2 days with a solution of a water-resistant mildew solution for 2 to 3 minutes. Water temperature 18 ~ 25 °C, after about 20 hours incubation of fertilized eggs began to release film. After the hatching of the fry, the fish nests are cleared and the broodstock is removed by pulling the nets, copying, and trapping in cages.
1.7 Fry cultivation Fish fry are hatched and then kept in ponds. Ponds are filled with water to increase the habitat of larvae. Using chicken manure and other compost to cultivate small-scale zooplankton for larvae feeding, supplement and feeding egg yolk; with the growth of larvae, feeding frequency and quantity gradually increase, increase soy milk, fish gills and so on. In the cultivation process, to keep the water fresh, adequate oxygen, sprinkle lime and bleach regularly, and add antibiotics and other drugs in the feed to increase the survival rate of fry.
2 Fish pond cultivation
2.1 Pond preparation Fish ponds require an area of ​​1500 to 3000 m2, water depth of 1 to 1.5 m, less silt, and complete injection and drainage facilities. Before laying the seedlings, use quicklime or tea seed cake to disinfect according to the conventional method, fill the water 50 to 60 cm, depending on the situation of fat thin in the pond, apply into the fermented manure dung and cultivate the natural biological feed.
2.2 Summer pond stocking pond stockings of about 2 cm per square metre, 30 to 50 tail pond summer flowers. After 20 to 25 days of cultivation, when the fish is more than 3 cm above seabass, 50 to 100 fish heads or carp fry are stocked per square metre, and a small amount of egg-suspended shrimp is used as a live bait and set of conventional fish species.
2.3 The feed is fed in the early stage of feeding egg yolk, soymilk and fish pulp, and is fed 3 to 4 times a day. In the middle and later stages, small miscellaneous fish gizzards, crushed snails, oyster meat and bean cake paste are fed and the amount of daily feeding accounts for the pool. 3% to 5% of fish weight. Stocking shrimp and fry can play a role in continuous feeding.
2.4 Water Quality Regulation Some aquatic plants such as water peanuts, water hyacinths, reeds, and wormgrass are transplanted in the pond to provide shelter and improve water quality. During the cultivation period, water quality indicators are often measured, and water quality is improved by adding water, changing water, using live microbial agents, and splashing lime to ensure that the dissolved oxygen is above 5 mg/L, the pH is within the range of 7.3 to 8.5, and the ammonia nitrogen is 0.2 mg/L. the following.
2.5 Prevention and control of fish diseases Adhere to the principle of prevention, and adopt methods such as combining external and internal medicines to prevent diseases. Common fish diseases and control methods: Saprolegniasis, each cubic meter of water with salt and baking soda 400g made of the mixture Quanchiposa, spilled again every 2 days; Parasitic disease, with 0.5 g / m3 crystal enemy 100 Insects or copper sulfate Quanchiposa; enteritis disease, with 1 g/m3 bleach Quanchiposa, while adding 0.3-0.4 g of furazolid per kilogram of feed made bait, feeding 2 to 3 days.
2.6 Daily management In the process of fingerling cultivation, it is necessary to visit the ponds on a regular basis and adhere to the “four-determined†feeding method. By adding water, changing water, fertilizing, and opening aerators, fresh water, adequate dissolved oxygen, and rich food organisms will be maintained. Sprinkle quicklime and bleaching powder on a regular basis. Disinfect the food table with 0.3-0.5kg of bleach every two weeks or so, and add antibiotics to the feed to increase the survival rate of the fingerlings.
