Triangular 鲂, common name 鳊, scientific name flat chest 鲂. It is a wild large-scale economic fish, mainly distributed in rivers, lakes and other water systems. The triangular body is beautiful in appearance, with a small head and high back, slightly "△" shaped. It is clearly distinguished from the head lice and squid in that its lip is thick and prominent and horny. The body is thick and fleshy, with less intermuscular thorns, and the meat is tender and scenty. It can be called a treasure in freshwater fish. Recently, due to the sharp increase in sales volume and the sharp drop in wild resources, the price of adult fish has risen steadily. The upsurge of artificial breeding of triangular fleas is rising across the country. The trifoliate seedling breeding and cage culture techniques are introduced as follows:
First, the larvae of the larvae that hatch and hatch from the fish must undergo post-embryonic development for 3 days to 5 days before they can be cultured in the lower pool (preferably with egg yolks). The ponds must be sterilized and fertilized before ponding. First test the water with the triangle fish “fish flowerâ€, observe the disappearance of pool water toxicity, and then put the fry. The water quality is refreshing, the transparency is above 40cm, and it is better to use thin water. The "fish flower" stocking density is about 100,000 per acre. Keep in mind that when the fishes are under the pond, they should not be too dense and should be operated with plenty of water. After the lower pool, feed 2 to 3 times a day soaked peanut bran and other refined bait 1.5 kg / mu, after the fish grow up gradually, while the appropriate amount of organic fertilizer sprinkling, training natural food.
After 30 days to 40 days of pond cultivation, the fry can grow to 5 cm to 6 cm long. At this time, the first net exercise can be performed and the sparse treatment can be performed. The fish can be divided into 20,000/mu to 30,000/mu. The fry can continue to be cultivated for 30 days to 45 days and can reach 8 centimeters. At this time, the second time sparsely, it is divided into 10,000 tails/mu. In the third year of breeding, the length of spring fry can reach 10 cm to 15 cm. After the first net exercise, exercise the fish once every 20 days and observe the growth of the fish. During this period, as the fry gradually grows, the amount of feed fed increases, and the quality of the water gradually becomes fat. Water quality should be changed depending on whether the water is thin and the activity of the fry is changed periodically or from time to time to maintain fresh water quality. Feeding methods for bait are similar to those for fry.
Second, develop cages
1. Selection of Water Areas Select deep-water reservoirs near villages and houses to set up fishing rafts. This can be easily managed, and it can avoid falling out of dry season cages. Should choose to Yangyang lee, the bottom of the original farmland or flat open waters. This kind of water quality fertilizer and natural baits are relatively abundant. The upper reaches and surrounding water resources of chemical fertilizer plants, pesticide plants, paper mills and other pollution sources should not be selected.
2. Net cages made of polyethylene nets were used for cage materials. Its specification is a hexahedral enclosed cage with a lid. The box is 4 meters long, 3 meters wide, 3 meters deep, and 3 cm mesh. A large-scale float ball and pine wood board is used to construct a bridge-type fishing raft. Generally, one fishing boat is installed with 20-50 cages.
3. Installation of cages The upper corners of the cage are tied to the four inner corners of the pine wood frame. The other side of the cage is wrapped with polyethylene to fix the edge of the cage to the edge of the frame. Two to three kilograms of pebbles or sandbags are hung on the corners to allow the cage to fully develop in the water. Net cages should be installed 7 days before the fish species are put into the box to make the meshes smooth after attaching the algae. This will prevent the skins and scales of the fish from being scratched. At the same time, it should be made of 40-mesh sieves to make it 2 meters and 2 meters high and 0.2 meters high. The square feed table is hung in a corner of the cage.
4. Fish Stocking In order to increase the survival rate and breeding efficiency of fingerlings, it is generally advisable to produce large-sized fingerlings with a tail weight of 50 grams or more and stocking about 100 tails per square meter. Starting from the 10 days before the fish is out of the pond, when feeding the feed, adding 1 cc of Vc per kilogram of feed can improve the immune function and anti-stress ability of the fish. Fish should be trained twice or three times before leaving the pond. The day before the fish species are laid, they should be raised in fish cages for 24 hours. This will reduce the loss of fish species in the transport process and improve the efficiency of the fish species. The survival rate.
5. Feed feeding The whole breeding process uses special pellets. The pellets are mainly made of fishmeal, vegetable cake, bran, etc. The pellets are made of small-diameter hard feed pellets with different particle sizes (particle sizes of 1 mm to 1.5 mm) and adult fish (2.5 mm to 3.5 mm in diameter). ). The content of animal protein in the pellets can reach about 26%. Feeding small fish feed at the initial stage of the breeding, the daily feed amount is 5% to 7% of the fish's body weight; the adult fish feeds are fed in the middle and later stages of the cultivation, and the daily feed amount is 3% to 5% of the fish body weight, and the feed is fed 3 times daily. In actual operation, it should also be flexibly adjusted according to the weather, water temperature, and food intake. It is generally appropriate to eat it in about 2 hours.
6. Daily management Generally, the cage is washed once every 7 days to 10 days to prevent clogging of the mesh and affect the flow of water inside and outside the cage. Check and clean the feed table every morning to prevent the residue from rot and spoil the water. At the same time, according to the situation of the leftovers on the previous day, the amount of feed on the day was decided. In addition, every day, check whether the cage is broken or slippery and repair it at any time to prevent fish escape.
Third, the fish disease prevention triangle cage large density of fish farming, fish disease prevention and control should be strengthened. Every two weeks around the cage, use 2510-6 to 3010-6 quicklime or 110-6 chlorine dioxide to splash water, once a day, for 2 days to 3 days. In addition, using small woven bags, each bag containing 100 grams to 150 grams of bleach or copper sulphate (alternate use), hung above the feed table, each bag hanging 1 bag, after adding the drug solution to prevent fish disease. In case of erythrodermic disease, each diseased cage can use chlorine dioxide 4g-5g watered once a day for 3 consecutive days, and add 1g to 1.5g of ciprofloxacin per kilogram of feed. Feed 3 days. In the event of saprophytic disease, the diseased fish can be soaked in 0.4-hour baking soda and salt solution for 20 minutes to 30 minutes. In case of rotting disease, each of the onset cages can be splashed with fresh lime 800g to 1000g, once a day for 3 consecutive days, and 5 grams of "Faraciteside" per kilogram of feed is fed continuously for 3 days.
First, the larvae of the larvae that hatch and hatch from the fish must undergo post-embryonic development for 3 days to 5 days before they can be cultured in the lower pool (preferably with egg yolks). The ponds must be sterilized and fertilized before ponding. First test the water with the triangle fish “fish flowerâ€, observe the disappearance of pool water toxicity, and then put the fry.

The name "goji" is a relatively recent name used for the species Lycium barbarum and Lycium chinense. In East Asia, these species have a long history of use as both a food item and for medicinal purposes. The fruits of this plant, the goji berries, have gained popularity over the past decade due to their promoted health benefits.
Our Low Pesticide Goji Berry is produced in accordance with the EU standards 0231010 : Tomatoes(goji berry is classified to tomatoes).
For the low pesticide goji berry, we control it in the planting process. A month or so before picking, it is forbidden for farmers to spray pesticides on the goji trees. In addition, we strictly prohibit farmers to use prohibited pesticides.
Of course, the types and quantities of pesticides need to be tested to confirm. We could offer organic certificate and test report, there are more than 200 items scanned by EUROFINS, Complies with EU standard.
