Experience of mixed culture of brocade carp and herring

In order to fully tap the production potential of the water body, mixed culture, close culture and rotational culture are often carried out in adult fish culture. If carp are mixed with herring in the same pond, because the bait is easy to get, the growth is fast and good. The commonly used ratio is 1 kilogram of herring fingerling, with a total length of about 13 centimeters of carp 2 million. If mixed with grass carp in the same pond, for every 1 kg of grass carp fingerling, there is only one carp with a weight of 50 to 100 grams. In intensive fish ponds with mixed culture and dense culture, in order to make fish get sufficient bait and grow rapidly, it is necessary to fertilize and reproduce natural bait and feed artificial feed.

First, the general principle of fertilization is to make the pool water quality reach and maintain "fat, live, tender and cool".

Second, the general principle of baiting is "even, sufficient and good". If the concentrate is fed completely, the daily feed intake can be calculated as 1: 5% of the fish weight gain.

Third, the "six four" should be achieved in daily management:

1. Early morning: early cleaning of the whole fish pond, early release of fish species, early feeding and early appointment of a special person to manage the pond.

Look: look at the activities of the fish, the changes in water quality, the weather, and the season at that time.

3. Siqin: frequently patrol the pond to observe, check the growth and health of the fish, clean the fish pond, prevent diseases, and study diligently.

4. Four defenses: prevent floating heads and flooded ponds, prevent fish diseases, prevent disasters and guard against theft.

5, four fixed: bait fixed quality, quantitative, timing, positioning.

6. Sixiao: fish seed disinfection, bait disinfection, tool disinfection, food farm regular disinfection.
