How much does crayfish seed stock cost per jin, and when is the best time to stock them?
Crayfish are a food we all enjoy eating regularly, whether in hot pot or stir-fried, each has its own unique flavor. There was once a joke saying that thankfully crayfish were artificially farmed, otherwise they would have gone extinct long ago, without even having time to become a protected animal, which shows how much our country's people love crayfish. So when carrying out crayfish farming, how much does crayfish seed stock cost per jin? And when is the best time to stock them?
1. How much does crayfish seed stock cost per jin?
The market price of crayfish seed stock is not fixed, which is to say there are expensive ones and cheap ones, and the key is how we make our choice. Currently on the market, crayfish seed stock is roughly around 15 to 20 yuan per jin. Generally, in crayfish farming areas the price of seed stock will be a bit cheaper, while in places far from farming areas it will naturally be more expensive; when buying, it is still best to base it on the local market conditions. If buying seed stock for the first time, it is best to choose ones with complete appendages, healthy and disease-free, and strong vitality, and later keep your own breeding stock.
When selecting shrimp fry, it is best to understand the source of the brood shrimp at the shrimp hatchery and whether it meets the relevant requirements. Choose fry provided by pollution-free hatcheries, and at the same time pay attention to whether medication was used during the hatching process, as medication may affect the fry's disease resistance during farming. Also do not choose fry that have undergone long-distance transport; in summer, fry transport time generally should not exceed 2 hours, and fry that have undergone long-distance transport have a lower survival rate after being put into the pond.
2. When is the best time to stock crayfish seed stock
Crayfish seed stock can achieve multiple crops of farming in one year, so shrimp fry can be stocked from April to June, June to August, and September to October. However, the better stocking time is during summer and autumn. Generally speaking, the farming effect of stocking shrimp fry in September-October > the farming effect of stocking brood shrimp in June-August > the farming effect of stocking shrimp fry in March-May.
When carrying out crayfish farming, pay attention to disinfecting the pond water; poor water quality may lead to large-scale death of crayfish. Also pay attention to the management and care of aquatic plants in the shrimp pond. If improperly managed, causing the aquatic plants to die will not only reduce the feed source for the shrimp fry, but also lead to a decline in the water body's self-purification capacity and deterioration of the environment, ultimately reducing the efficiency of biological feed cultivation and feed utilization.
The above is some knowledge about crayfish farming. When carrying out crayfish farming, be sure to carefully consult relevant materials, learn the relevant techniques of crayfish farming, and also consider the local natural environment and market conditions. Do not carry out crayfish farming blindly, so as to avoid losses during farming.
