The precautions for fish farming can be summarized into the following aspects to ensure the smooth progress of farming and the healthy growth of fish:
1. water quality management
Water source selection: choose clean, pollution-free water source for breeding, avoid the use of water containing harmful substances.
Water oxygen content: maintain a good level of dissolved oxygen, the use of aeration equipment or oxygen device, to ensure that the fish can breathe normally.
Temperature control: According to the needs of different fish, the temperature of the water body is reasonably controlled to provide a suitable growth environment.
PH value and hardness: according to the water quality requirements of the fish, adjust the PH value and hardness of the water body to maintain stability.
2. healthy breeding
Diversified feed: provide a variety of feed, including live bait and feed pellets, to meet the different nutritional needs of fish.
Prevention of disease:
Regularly check the fish condition, eliminate weeds, residual baits, dead fish and parasites in the pool, etc., to prevent the occurrence and spread of diseases.
Control pathogens from the beginning, such as cleaning the pond before stocking, draining the pond water, removing the surface sludge at the bottom of the pond, insolating and removing weeds at the edge of the pond, so as to eliminate pathogens and parasite spawning sites.
The incidence of parasitic diseases that occur only in certain types of fish can be reduced by a variety of fish.
Choose pure line varieties or other excellent varieties with strong disease resistance and stress resistance, and try to avoid inbreeding or "hairy fish" breeding offspring seedlings.
Reasonable density: according to the size of the breeding pond and fish species and other factors, control the density of fish stocks to avoid the spread of infectious diseases caused by overcrowding.
Regular water change: regular cleaning of aquaculture containers, and the right amount of water to keep the water clean.
3. feed management
Reasonable feeding: according to the needs of fish and growth stage, reasonable feeding, avoid waste and excessive feeding.
Feed quality: Choose good quality feed to ensure that fish get adequate nutrition. It is recommended to choose a full-price pellet feed with high-quality nutrient balance, and pay attention to the content of energy, fish amino acids, essential fatty acids, trace elements, and protein in the feed.
Timing and quantitative: Establish a scientific timing and quantitative feeding system to develop the habit of fish eating on time.
Nutrient balance: to ensure that fish intake of carbohydrates, fat, protein and other nutrients, and according to the need for appropriate formula adjustment.
4. Other Considerations
Predation prevention: reasonable anti-predation measures are set up to avoid fish being invaded by predators.
Water circulation: through circulating water system or additional filtration device, keep the water clean and fresh.
Regular observation: regular observation of fish behavior, growth and water quality, etc., found that the problem solved in time.
The above precautions are some key points in the process of fish breeding. Through reasonable management and breeding measures, the breeding efficiency can be improved and the healthy growth of fish can be ensured.
