What is the most appropriate energy-to-protein ratio for fish feed?
Since the first requirement of fish in taking in nutrients is to meet their energy needs, from the perspective of fish nutrition, energy is the foundation of fish feed quality. The energy in feed is the sum of the energy contained in the three major nutrients in the feed - protein, fat, and carbohydrates. As a nutrient, protein is not only a major energy-supplying substance, but also has extremely important physiological functions, and these physiological functions cannot be replaced by fat and carbohydrates, and fish have a particularly high demand for protein, so protein is

Remedial and Management Measures for Fishery Production After a Disaster
Recently, in some areas of our province, continuous heavy rains caused many aquaculture ponds to overflow and fish to escape, bringing relatively large losses to farmers. Doing a good job of remedial and management work for fishery production after the disaster has become an important task for aquaculture farmers at present. Based on years of experience in fishery work, the author proposes the following measures for the reference of the broad community of farmers. 1. Remedial measures for fishery production after a disaster. 1. Surround the fish pond with netting. When floodwaters recede, surround the fish pond with netting at the appropriate time to prevent fish in the pond from continuing to escape, thereby reducing losses. 2. Restock fry and fingerlings

How can recreational fisheries be developed? A few suggestions for reference
The question of how to develop our country's recreational fisheries attracted great attention from the relevant departments many years ago. In its 2000 fisheries development goals, the Fisheries Bureau of the Ministry of Agriculture clearly stated: it is necessary to adapt to changes in the consumer market and actively develop recreational fisheries in places where conditions permit. Subsequently, recreational fisheries have developed in some areas of our country. Relevant experts point out that recreational and ornamental fisheries, as a new phenomenon emerging in the process of fisheries structural adjustment, are still at the primary stage, and there are still problems such as incomplete facilities and

Application of Artificially Hatched Artemia in Industrialized Cultivation of Yellow Catfish Fry
1. Wide-ridge double-row planting method: This method transplants rice seedlings in a sequence of 6 cun, 12 cun, 6 cun. Its advantages: First, the total number of hills per mu (16,000 hills) is slightly less than that of monoculture rice, but yield increases through ventilation and light penetration; Second, it provides more than 7 hours of light daily, raises water temperature, and allows plankton to reproduce and grow rapidly, creating good conditions for providing natural food organisms for yellow catfish; Third, it broadens the activity space for yellow catfish, enables large-scale pest elimination, and fish feces serve as fertilizer, increasing rice yield. 2. Rice management: Rice cultivation management strictly follows

Stocking fish fingerlings in cages in autumn has many benefits, and the timing of release matters
After autumn fertilization in the pond, fish fingerlings are generally in robust health and adapt easily to the cage environment. At the same time, overwintering in sunken cages in large water bodies not only consumes less body weight in the fingerlings than overwintering in ponds, but also, after overwintering ends and the cages are raised in spring, the fish begin feeding earlier, and their growth period is extended by about 1 month compared with fish stocked in spring, so the fish grow quickly and production increases noticeably. Compared with fingerlings stocked in spring, fingerlings overwintered in sunken cages grow about 30% faster and are about 35% larger in size when removed from the cages. Therefore, stocking fingerlings in cages in autumn for overwintering is a relatively scientific

How to Safely Transport Live Fish? A Full Breakdown of Practical Methods
1. Sealed transport: Sealed transport places the fish and water in a sealed, oxygen-filled container for transport. Its characteristics are small volume and easy portability; for general adult fish transport, within 8 hours there is no need to change the water midway, the seal is tight, and the survival rate is high. A single oxygen fill can keep fry alive in the container for more than 20 hours, and it is even more convenient for long-distance transport of large quantities of fry and fingerlings. Methods such as oxygen-filled sealed transport in plastic bags and oxygen-filled sealed transport in plastic buckets can be used. 1. Oxygen-filled sealed transport in plastic bags: Fill the plastic bag with clean clear water, with the water volume accounting for 1/3 of the bag's total capacity
