What are the important factors to pay attention to in the process of fish farming?
water quality management
Water quality is the core condition for fish survival, and daily monitoring of dissolved oxygen (maintaining above 5mg/L), non ionized ammonia (<0.02mg/L), and nitrite (<0.1mg/L) is required. During the high temperature season, oxygenation equipment (1.5-3kW per acre for ponds) should be equipped, and water should be changed scientifically (1/5-1/3 per week for ponds and 1/4-1/3 per week for fish tanks) to avoid temperature differences exceeding 2 ℃.
Breeding density
Reasonable control of aquaculture density is the key to ensuring the healthy growth of fish, which needs to be adjusted according to water capacity and fish species to avoid competition pressure or deterioration of living environment caused by insufficient space.
Temperature and dissolved oxygen
When the water temperature exceeds 28 ℃, the dissolved oxygen drops sharply. It is necessary to avoid feeding during the high temperature period at noon and choose to feed in the morning or evening. Most fish grow best at temperatures between 20-32 ℃, exceeding 32 ℃ will reduce their food intake, and temperatures above 36 ℃ may be fatal.
Feeding management
In summer, easily digestible feed (protein 28% -32%) should be selected, and the feeding amount should be controlled to be consumed within 5-10 minutes, which is about 60% -80% of that in spring and autumn. Large fish can be fasted for one day per week, and adding vitamin C and probiotics to their feed can enhance their stress resistance.
disease control
The incidence of bacterial diseases during the high-temperature period is 2-3 times higher than that at room temperature, and disinfectants (such as potassium persulfate) or immunopolysaccharides need to be used every 15 days. Common diseases include bacterial enteritis, gill rot disease, etc., which need to be prevented in advance.
