How to breed yellow spicy tench?
In recent years, yellow and spicy tench has gradually become a popular species in aquaculture due to its delicious meat and rich nutrition. This article will combine the hot topics and hot content on the Internet in the past 10 days to introduce you to the breeding technology of spicy tench in detail and help you carry out breeding work efficiently and scientifically.
1. Basic characteristics of spicy tench
Yellow tench, whose scientific name is yellow catfish, belongs to the order Catfish and is mainly distributed in the Yangtze River, Pearl River and other river basins in my country. It has fast growth speed and strong adaptability, and is suitable for breeding in various environments such as ponds and cages.
| Features | Description |
|---|---|
| growth cycle | Market size (150-200 grams) can be reached in 6-8 months |
| Suitable temperature range | 15-30℃, the optimal temperature is 22-28℃ |
| Food habits | Omnivorous, preferring animal food |
2. Preparation of breeding environment
Yellow spicy tench has high requirements on water quality, so the following preparations need to be made before breeding:
| Project | request |
|---|---|
| Pond Siting | Sufficient water source, convenient drainage and irrigation, shelter from wind and sunshine |
| water quality | pH value 6.5-8.5, dissolved oxygen ≥5mg/L |
| Clear pond disinfection | Sprinkle quicklime or bleaching powder all over the pool |
3. Seedling selection and stocking
High-quality seeds are the key to successful breeding. It is recommended to select seedlings with neat specifications and strong vitality, and adjust the stocking density according to the breeding mode.
| Breeding model | Stocking density (tail/acre) |
|---|---|
| main support | 8000-10000 |
| mixed culture | 3000-5000 |
4. Feed management
The feed for spicy tench is mainly compound feed with high protein content, and the feeding needs to follow the principle of "timing, fixed point, and quantitative".
| growth stage | Feed protein requirements | Daily feeding amount (% of body weight) |
|---|---|---|
| Seedling stage | ≥40% | 5-8% |
| Adult stage | ≥35% | 3-5% |
5. Disease prevention and control
Common diseases of yellow tench include enteritis, saprolegnia, etc. It is necessary to focus on prevention and regularly disinfect the water body.
| Disease name | Symptoms | Prevention and control methods |
|---|---|---|
| enteritis | Anal redness and swelling, food refusal | Add 0.1% allicin to feed |
| saprolegnia | Cotton-like hyphae on body surface | Soak in 3% salt solution for 10 minutes |
6. Key points of daily management
1.water quality monitoring: Check pH value, ammonia nitrogen and other indicators every week, and change water in time.
2.Pond patrol observation: Patrol the pond every morning and evening to record fish activities and feeding conditions.
3.growth record: Measure the body length and weight randomly every month, and adjust the feeding strategy.
7. Market Prospect Analysis
According to recent industry data, the market price of yellow and spicy tench is stable at 25-35 yuan/jin, and consumer demand is increasing year by year. Using scientific breeding technology, the yield per mu can reach 1,500-2,000 kilograms, with significant economic benefits.
Through the above systematic breeding technology management and combined with market demand, spicy tench breeding will become a new growth point in the aquatic industry. It is recommended that farmers pay close attention to industry trends and adjust the breeding scale in a timely manner.
