The role of fertilization in fish ponds is mainly the reproduction of plankton, epiphytic algae, zoobenthos, and other natural foods. After fertilization, microorganisms multiply, organic debris increases, providing abundant food resources for fish species such as cockroaches and cockroaches; Organic fertilizers can be eaten directly by fish such as cockroaches and clams. Fish pond fertilization in spring should pay attention to the following matters:

1. The organic fertilizer must be fully fermented. The water temperature in the fish ponds in spring is low, and the oxygen content in the water is relatively abundant. Reasonable application of organic fertilizer is not only low in cost, but also can achieve good breeding results. Fish ponds, such as manure, livestock and poultry manure, must be fully fermented. Fermentation and decomposing of fertilizers with organic matter applied to fish ponds can reduce the consumption of oxygen in the water, can be quickly absorbed and used by phytoplankton, and can also kill pathogens in organic fertilizers.

2, the principle of fertilization less Shi Heng Shi Qin Shi, the so-called "less applied", that is, each time the application of organic fertilizer tens of kilograms per acre to 100 kilograms; the so-called "uniform application", that is, water and manure evenly spilled, so that the fish The water color of the pond is yellow-brown or oil-green. The surface of the pond is oil-free and its transparency is kept between 20 cm and 30 cm. The so-called “drinking ground” means that as the fish’s feeding rate decreases, the pond’s water content decreases and the transparency is greater than 30 cm. Re-fertilize.

3, due to the fish system should determine the amount of fertilization is not the main turtle, fish pond, due to feeding feed, the amount of fertilizer in the spring should be reduced accordingly, so that the transparency is maintained at 30 cm to 40 cm; with the temperature rise, pond water fertilizer It will get bigger and bigger. Intensive breeding of fish ponds with high yields of squid and intensive culture of grass carp, although they have raised some squid and carp, they should not be fertilized in spring.

4, fertilization time Sunny morning is good to pay attention to listen (see) the weather forecast, not cloudy, rainy fertilization. Phytoplankton grows through photosynthesis and fertilizes in the morning on sunny days from 2 days to 3 days. It can quickly and best promote the proliferation of microorganisms, minimize the pollution of organic fertilizers on water quality, and ensure the benign circulation of fish and pond materials. .

5, regular changes in water to keep the water fresh if the accumulation of organic waste of fish and ponds and various types of biological waste, oxygen content in the water decreased, poor composition of plankton, it will affect the growth of farmed fish. Therefore, it is necessary to change the new water regularly so as not to overload the fish ponds and keep the water quality “fat, live, tender and cool”.

Canned Tuna is an important variety of canned fish, canned tuna processing is the main species of albacore tuna and yellow-fin tuna, canned tuna has many varieties, including Canned Tuna in Brine, Canned Tuna in Tomato Sauce, Canned Tuna In Sunflower Oil, Canned Tuna in Vegetable Oil. In addition the tuna muscle more sulfur-containing protein, generally use the anti sulfur acid tin coating as a whole and canned container.

Canned fishes are made in our sub company-Zhejiang XingWang LongSheng Food Co.,Ltd. The company now has two factories(can branch and loin branch) and the main production equipment are: 3 processing capacity of 60 mt(materials)/day canned fish production lines; 4 processing capacity of 50 mt(materials)/day frozen cooked tuna loin production lines; 3 freezing capacity of 80 mt/day freezer rooms and 1 disposing capacity of 1000m³/day waste-water treatment plant. All the key equipment of every plant are imported from Thailand or Japan.

We will always strive to create more delicious, natural and safer marine health food.
