What kind of fish is good to raise in the south? Top 10 popular fish species recommendations and breeding tips
Recently, the topic of aquaculture in southern China has been hotly discussed on the entire Internet. Taking into account climate characteristics and market demand, this article has compiled data on popular fish species in the past 10 days to provide scientific reference for farmers in southern China.
1. The influence of southern climate on fish farming
The average annual water temperature in the south is 18-28°C, with a long rainy season and high dissolved oxygen, which is suitable for the growth of most warm-water fish. But please note:
1. Oxygen needs to be added during the high temperature period in summer
2. Take preventive measures during typhoon season
3. Insulation and antifreeze during winter cold waves
| Ranking | Fish species | Suitable temperature range | growth cycle | Average market price (yuan/jin) |
|---|---|---|---|---|
| 1 | Tilapia | 16-38℃ | 5-6 months | 8-12 |
| 2 | grass carp | 20-32℃ | 10-12 months | 6-9 |
| 3 | seabass | 15-30℃ | 8-10 months | 18-25 |
| 4 | yellow catfish | 18-34℃ | 7-9 months | 15-22 |
| 5 | mandarin fish | 20-28℃ | 12-15 months | 35-50 |
2. Key points of popular fish species breeding
1. Tilapia
• Strong resistance to hypoxia
• Feed conversion ratio 1.5:1
• Stocking 2,000-3,000 animals per acre
2. California bass
• Requires graded breeding
• Protein requirement ≥40%
• Pay attention to the prevention and treatment of rotten diseases
| Fish species | pH value requirements | Dissolved oxygen requirements (mg/L) | Common diseases |
|---|---|---|---|
| grass carp | 6.5-8.5 | ≥4 | Hemorrhagic diseases, enteritis |
| yellow catfish | 7.0-8.5 | ≥5 | Saprolegnia, melonworm |
| mandarin fish | 6.8-8.0 | ≥6 | viral hemorrhagic disease |
3. Recommended breeding models
1.Aquaponics system: Suitable for family farms, saving 30% water
2.Raised pond culture: Suitable for high-value species such as bass and mandarin fish
3.Integrated rice and fish farming: Increase income by 2,000-3,000 yuan per mu
4. Market trend analysis
According to the latest e-commerce platform data:
• Prepared dishes drive demand for seabass up 47%
• Sales volume through community group buying channels increased by 65% year-on-year
• Live fish transportation loss rate reduced from 15% to 8%
5. Expert advice
1. Choose 3-5 varieties for mixed breeding to reduce risks.
2. Register a brand to increase added value
3. Pay attention to the new regulations on "aquaculture tail water treatment"
4. Using IoT monitoring equipment can increase the survival rate by 20%
Fish farming in the South should select species based on local water quality, traffic conditions and consumption habits. It is recommended that novices start with tilapia or grass carp and gradually develop specialty farming.
