If there is enough water, it is ok to breed with good water quality, but the relative stability of water quality is poor. At present, Zhejiang Province is rich in aquatic products. In recent years, the prices of aquatic products have been generally stable, and even the prices of most aquatic products have declined steadily. Therefore, what to raise mainly depends on the local market, environmental conditions of breeding, local feed resources, breeding technology, management level, seed source and local consumption habits, and it cannot be generalized. Generally, the benefits of breeding famous and special varieties are relatively high, while the benefits of ordinary conventional varieties are low but the market is large. Now I would like to recommend several breeding varieties for your reference: 1. If you have abundant grass resources, you can consider mainly raising grass carp, or raising ducks and mixed silver carp. There are 2 species of grass carp in stock, one is about half a catty (total mantissa 150) and the other is about 0/5-20 per catty (total mantissa 250); In addition, 300-400 silver carp are stocked; Can be the proper polyculture of crucian carp, bream and bream. 2. If there are feed fish resources, you can consider cultivating carnivorous fish, such as perch (California perch, sea bass) or snakehead. In general, bass culture puts about 5 cm fish in1300-1600, and another 200-300 silver carp are mixed. If snakehead is farmed, the number of stocked fish is much larger. You can't raise ducks in this way. 3, turtle breeding, first of all, there must be escape prevention measures, ecological farming is ideal. If you want to get quick results, you can put about half a catty of turtle species, 1500-2000, and polyculture 250-300 silver carp. By the end of the year, more than 70% of soft-shelled turtles can reach 1 kg. If turtles are cultured, the number can be increased appropriately, but the growth rate of most turtles is much slower. You can't raise ducks in this way. 4. Shrimp culture. Generally, single-cultured freshwater shrimps are released from mid-June to mid-July every year, with 60,000 to 80,000 shrimps per mu; If you put shrimp, the quantity can be reduced appropriately. If fish and shrimp are mixed, from mid-July to mid-August every year, there are 6.5438+0.5 million shrimps about 2 cm per mu. In addition, fingerlings of flowers or silver carp should be interplanted in shrimp ponds in summer (1000- 1500). You can't raise ducks in this way. 5. Penaeus vannamei (generally 50,000-60,000 per mu) or Macrobrachium rosenbergii (generally 30,000-40,000 per mu) can also be cultured, but these two kinds of shrimps are generally stocked in May, but they need to be caught before the end of 10. You can't raise ducks in this way. 6. Monopterus albus culture: escape prevention measures are needed, and the bottom of the pool is hard. Generally, the number of eel species with 20-30g tail is 60- 100 /m2, and the number can be appropriately increased if the culture technology is good. Raising Monopterus albus requires a higher variety of Monopterus albus and requires artifacts. You can't raise ducks in this way. 7. Other conventional breeds that can raise ducks (ducks should be netted) and are suitable for your breeding are: tilapia, freshwater pomfret, mullet, crucian carp, bream, bream and so on. I won't introduce them here. 8. Other famous and special species that can be cultivated are frog, catfish, loach, fish sentence, fish shed, barracuda, Pelteobagrus fulvidraco, loach, eel and diced fish. I won't introduce it here.
