9 Tips to Increase Your Fish Fry Survival rate
How to Increase Fry’s Survival Rate
How to increase fry survival is a key concern for fish farmers. This is especially true in transporting and breeding fry. Fry mortality can easily occur if this is not addressed. A high fry mortality rate directly impacts the efficiency of fish-pond breeding. How can you increase the survival rate of fish fry? What are the most important things to remember when raising fish fry. Here are 9 tips to increase the survival rate of fish fry.
How Many Fish Fry You Should Feed
How often should fish fry be fed? Fry is a key factor in how to increase the survival rate of fry. This is different than feeding adult fish. Small fish require constant food. It is important to keep an eye on their diet. Don’t overfeed or overfill them. Instead, divide the food into smaller portions throughout the day.
The fish fry should be fed every 3-4 hours in the beginning. Gradually increase the frequency of feeding. The first two to three feedings in the morning should be done at an hour intervals. After a break of 3-4 hours in the afternoon, feed the fish fry every two hours for about 6-8 times per day. It is recommended that fish fry be fed 3-4 times per day after a month. Fish fry can be reduced to 2 or 3 times per day after a few months. If you need to make floating fish feed, our fish feed machine is the best choice.
9 Tips to Increase Fry Survival Rate
- Fry are generally not fed the day they arrive in the pond. This is to allow them to adjust to the environment and then start eating the next day.
- Before entering the pond, fish fry must clear the pond and remove all debris. Before releasing fish fry, confirm that any drugs are gone and that they have adjusted to the new environment.
- To increase the survival rate of fry, pay close attention to the water’s dissolved oxygen level.
- Temperature difference can cause excessive stress in fry. To avoid this, the temperature difference between the nursery bag temperature and the pond temperature should not exceed 2. The nursery bag can then be placed in the water for half an hour. To increase the survival rate of fry, temperature control is essential.
- To avoid fish being blown off the shore by wind gusts, place the fry upwind of the pond. The pond is small and fish can’t spread out quickly.
- The fry are damaged during transportation. Fish that have been transported long distances will be weaker and less able to resist stress. It is possible to become infected with pathogenic microorganisms. To increase the survival rate of fry, it is important to use anti-stress and disinfection techniques.
- This is to protect fry from their natural enemies. To ensure that harmful organisms are completely eliminated from the aquaculture water before the fry are put in the pond, it is best to remove the net at least a few days in advance.
- To avoid any adverse effects from size or specification differences on individual feeding and growth, put the same batch in the same fish pond.
- The fish seedlings should be eating less for the first 30 days. It is important to spread the food evenly around the pool so that they eat evenly.
These 9 tips to increase the survival rate of fry are just suggestions. You should take care of your fish fry according to your actual situation. These 9 tips will help you improve the survival rate of your fry.
Learn How to Care for Fish Fry
1. Reasonable Stocking of Fry
The key to improving the survival rate of fry is breeding large-sized fry in autumn. Stocking should be done according to actual conditions. A fish pond of 1.5m depth can house 4,000 to 6,500 fish fry. The body length can reach 13-17 cm by the end. This is important for increasing the breeding yield.
2. Separation Management
It is important to divide the fry according to their different specifications. This will ensure that they get enough food and prevent the smaller fry from getting bored. The adult pond should have fry over 5 cm in size. Small fry must be kept separate from the larger fry.
