Site of the golden pond: a more scientific configuration than windwater
The success or failure of grassfish farming is often doomed at the site selection stage. High-quality ponds need to meet three main elements: live water, clay base, and transport. On site, it was found that farmers in the lake's north-hond lake use the "third-class ladder pond" to switch water from the natural water level difference, saving 30 per cent of electricity costs. The bottom of the pond shall be made of clay layer of less than 15 per cent sand, which is more than three times more water-preserving than the average fish pond. Transport costs can be reduced by 40 per cent in fish ponds within 2 km of the main main road, a data that has been validated by measurements from the hunan changde farm base。
Fish seed selection black technology: the five main tricks of eye recognition
High-quality seedlings are key to profitability. Experienced breeders will capture the three points: see body size (length/higher than 3. 5:1), vibrancy (sunk within 10 seconds of water) and silk (fresh as coral). In 2023, the new species, yangtze 2, grew at a rate of 22 per cent faster than the normal species, provided that they were accompanied by special feed. Remember to avoid three types of poor-quality seedlings, which have less than 30 per cent survival, with "injury, deformity, white thorium"。
Precision feeding programmes: a 40 per cent reduction in feed costs
The innovation is based on the "3+2 feeder" method: 32% of the protein content was used in the first three months and 28% of the particulates were used in the next two months. The guangdong zhongqing farm shows that this programme can reduce the meat ratio from 2. 0 to 1. 6. Four feeding sessions per day, at 6 p. M., 10 p. M., 14 p. M., and 18:00 p. M., each feeding session is well controlled at 15 minutes of fish. There is regular monthly addition of garlic and fungi and a 65 per cent reduction in the incidence of intestinal diseases。
Water quality control black box: dissolved oxygen intelligence monitoring system
Dissolved oxygen must remain above 5 mg/l, and less than 3 mg/l triggers float. A web-based monitoring system has been introduced at a farming base in jiangsu salt city, where six indicators such as ph, ammonia, etc. Are viewed in real time through a mobile phone app. Water exchange is controlled at 30 per cent per week, using the "first in line" approach. Algae are cultivated in such a way that silican algae water is more suitable for grassfish growth than green algae water, with transparency maintained at 30 cm. Special attention is to be paid in winter to the improvement of the bottom, with 200 g per cubic metre of water being spilled into the potassium persulphate compound。
New weapons for disease control: the chinese herbs alternative antibiotics programme
Natural prevention and treatment programmes have been developed for three common diseases: intestinal inflammation with five times the amount of cuisine, haresis with a yellow end, and skin disease with ground grass. The treatment rate of these herbal programmes is more than 85 per cent and there are no drug residues. A total of 20 kg/acre of raw lime is disinfected on a regular basis every month, effectively killing 98 per cent of the fungus. Particular attention will be paid to the control of the wheelworms, with the use of bitter leaves to press 5 kg/acre water。
Fishing time password: pre-autumn premium policy
The large number of traditional farmers were concentrated on the market at the end of the year, leading to price trampling. Smart breeders aim at the mid-autumn and national holidays, using the "net-lifting trap" method 20 days in advance, to catch more than three pounds of big fish. In the case of lake zhejiang, the price of grassfish during the festival was $2. 8 per pound higher than usual. Using the catch-and-take model, two more batches of fish could be produced each year, with an increase of 600 pounds in acre production. A 48-hour stopover before transport is required and 0. 5 per cent vc stress added。
Innovative profit patterns: wealth codes for cross-border integration
The profits from selling live fish are limited, and the guangdong middle mountain farm has developed a deep-processed product called "grass fish for three meals": fish made of canned, fish head made of soup, fish bone made of calcium, with a 300 per cent increase in profit. In cooperation with catering enterprises, a "fishing pond" model is being developed, and clients are entitled to an 80% discount on pre-paid farming. A more innovative "symbiotic" system, with an extra $2,000 per acre for the planting of hollow cabbage on the surface. The electrician channel will focus on building a three-kilogram household package, which will reduce logistics losses from 15 per cent to 5 per cent。
This field-tested farming system has helped the owner of zhang, a farmer in hubei county, to earn millions of dollars per acre. Remember: success = science management x technology innovation x market insight. Now is the best time to transform the old ponds, and it is likely that the market will have to phase out by missing this wave of industrial upgrading。
