How much do crayfish fry cost? Pay attention to these six points for higher yields when farming
Crayfish, also known as red swamp crayfish, freshwater crayfish and so on. Because its meat is fresh and delicious, it is very popular among people, and today it has become a common dish on people's tables, so crayfish farming has also become hot. So, how much do crayfish fry cost? What are the advantages of farming crayfish? What points should be noted to make crayfish more productive? Let's take a look together!
1. How much do crayfish fry cost?
Crayfish fry sell on the market for about 20-40 per jin, varying according to size and quality. It should be noted that crayfish currently have only one variety; there is no so-called hybrid variety. Some unscrupulous sellers use hybrid varieties as a cover to deliberately drive up the price of crayfish fry, and special attention should be paid to this. When crayfish are stocked, the yield generally peaks in the first year and then declines year by year. The life cycle of crayfish is 16-18 months. Due to inbreeding in the later period, reduced disease resistance and other reasons, production will decline or even be completely lost.
2. Advantages of farming crayfish
1. Large market potential
Crayfish are in great demand, from small barbecue stalls to high-end restaurants, and the market supply is less than the market demand. This supply-short-of-demand relationship gives the crayfish farming industry good market prospects and economic benefits.
2. Low farming difficulty
Compared with other farmed species, crayfish are easier to farm. Crayfish have strong environmental adaptability and few diseases, and can be farmed at high density in ponds or swamps.
3. Low farming cost
Crayfish are omnivorous, so feed is easy to supply. When farmed at low density, no special feed is needed. They grow quickly, have high yields, high energy conversion rates, low farming costs and good benefits.
4. Short farming cycle
Crayfish can generally be harvested and sold after about two months of farming. The large ones are caught and sold, while the small ones are left to continue growing, allowing continuous year-round returns.
3. Points to note when farming crayfish
1. Fry
There is only one variety of crayfish. At present, crayfish fry are easy to buy on the market, and natural fry resources are abundant.
2. Water quality
When farming crayfish, pay attention to water quality. Crayfish farmed in better water quality are more productive and have fresher, more delicious meat. The aquatic plant coverage in the pond should reach about 50%, the water transparency should be above 30cm, the dissolved oxygen content should be greater than 5mg/L, and water should be changed regularly. In summer, the water level in the pond should be kept above 80cm.
3. Feed
Crayfish are omnivorous animals and have a relatively high protein intake. They can be fed small trash fish, river snails, plant feed and so on. Of course, compound feed with a protein content of no less than 30% can also be fed.
4. Diseases
Crayfish farming density is generally relatively high, so disease prevention must be watched at all times, and drugs should be used regularly for prevention. Disinfect with chloride once every half month.
5. Mixed farming
Special attention should be paid to the fact that crayfish cannot be mixed-farmed with carnivorous or omnivorous animals, otherwise it will affect crayfish yield and lead to farming failure.
6. Management
Crayfish should be fed bait on time. In addition, absolutely avoid overfeeding animal offal, which causes the water to stink and affects crayfish growth.
