Long-distance transportation of fish, how to ensure that fish do not die, how to transport fish safely

Keep low temperature: Long distance transportation of fish must control the temperature, low temperature can reduce the activity of fish, reduce the consumption of energy and oxygen. | | Leave an air layer: In order to avoid the lack of oxygen during the transportation of fish, it is better to leave an air layer in the container. | | Prepare medicines: If you want to prevent the deterioration of water quality, you'd better add penicillin, salt and other medicines to the water. | | Note the density: The containers used for transportation are limited, so the density should not be too large.

1. to maintain a low temperature

for long-distance transportation of fish, in order to ensure its survival, the first thing is to control the temperature. Unlike daily fish farming, it is better to have a lower temperature during transportation, because in low temperature environment, fish are reluctant to move, so they can naturally save their strength, consume less oxygen, and have a stronger tolerance to the environment.

2. Leave an air layer

in order to ensure that the fish can breathe during transportation, it is necessary to leave an air layer in the fish container, that is, do not fill the water, water and air contact, so that when shaking, part of the air can enter the water, so as to maintain the dissolved oxygen in the water, so as to avoid the phenomenon of fish anoxia. Threatening its life.

3. there will inevitably be some problems in the transportation of drugs

, water quality may be rotten, and may even be infected with fish diseases, in order to avoid these situations, it is necessary to put some drugs in advance, such as penicillin, salt and so on. Among them, 4 million to 8 million units of penicillin are used per cubic meter, and 1-3 kilograms of salt are added per cubic meter.

4. Pay attention to density

. To ensure the survival of fish, we should also pay attention to the density of transportation. If it is finished fish, one cubic meter of water can transport 700-800 kilograms of fish, if you want a longer time, you can only transport 500-600 kilograms of fish. For fish fry, one cubic meter of water can transport about 8-10 million fish.
