Squid is a typical carnivorous fish, and only eat live fish live shrimp, but the single carp needs to have sufficient food and fish matching, technical requirements are high, such as raising carp in adult fish pond, can make full use of water Competitors of farmed fish such as wild fish are cleared to excavate pond productivity and increase efficiency. However, in recent years, some farm demonstration households have reported that the survival rate of the carp they raise is very low, and almost none, and they lose it. With confidence, the main reason for the low survival rate through investigation and analysis is that the stocking specifications are small, most of which are below 3cm. The fish rearing ponds have poor feeding ability and adaptability to the environment. Second, the stocking capacity is large, and some acres are released 80-100. At the end of the year, coupled with the lack of appropriate food, it is bound to cause fratricide. Third, poor water quality of the pond, often lack of oxygen; Fourth, the prevention and treatment of fish disease is not timely and do not pay attention to medication.
In view of the above situation, the following measures should be taken in the aquaculture production to effectively increase the survival rate of squid.
First, raise the stocking size of the squid and ensure that the size of the squid reaches 5cm or more;
Second, according to the source and quantity of pond food, a reasonable stocking should be conducted. Generally, 667 M2 should be suitable for 20-30 tails, and appropriate amount of seeded shrimp, squid or tilapia should be stocked in front of the squid species to allow them to breed naturally and ensure the squid. At 5-10cm, there are enough shrimps to eat, and more than 10cm have plenty of fish feeding.
The third is to strengthen water quality management, regularly inject new water, use micro-ecological preparations and net reform to improve water quality, and rational use of oxygen aerators, so that “three open and two can not be opened.†(If you find that the squid has spit out the bait fish Immediately start the aerator and add new water, and transplant a small amount of water peanuts to purify the water and create a good growing environment;
The fourth is to strengthen disease prevention and ensure that “prevention is the main thing and prevention and control are combined.†First, the fish ponds need to be cleaned and disinfected; secondly, when other fishes use drugs, the degree of tolerance of the catfish must be considered, and even less. Drugs that are more sensitive to it, such as trichlorfon and cupric chloride.
In a word, in order to raise the squid in adult fish ponds, it is only based on its biological characteristics and scientific breeding that good economic benefits can be achieved.
