Embodiment 1

[0020] Time and place: March 13-18, 2011, Wujin, Changzhou, Jiangsu.

[0021] The steps of fishing, loading and high-density transportation are as follows:

[0022] (1) Anti-stress: Add vitamin C (provided by Guangdong Huizhou Sanbao Biochemical Technology Co., Ltd.) to the feed at a rate of 3 g / kg feed every day for 7 days before seed fishing, and add vitamin C at a rate of 1 g / cubic every other day The proportion of rice water body is splashed with high-stable vitamin C (Sanbao high-dimensional C, provided by Guangdong Huizhou Sanbao Biochemical Technology Co., Ltd.) to improve the anti-stress ability of seedlings; stop feeding one day before fishing, so that Empty the digestive tract of seedlings, reduce the amount of excretion and intestinal damage during transportation, and avoid polluting the transportation water during transportation;

[0023] (2) Fishing: The water temperature in the fish pond is 8°C. Use a 15-mesh polyethylene mesh net to catch seedlings. The operati...

Abstract

The invention relates to a fishing, loading and high-density transportation method for megalobrama amblycephala fries. The method comprises the following steps of: (1) resisting against stress: before fishing fries, periodically adding a certain amount of vitamin C into a feedstuff and spilling high-stability vitamin C into an entire pond; and stopping feeding of the feedstuff one day before fishing; (2) fishing: laying a polyethylene net to fish fries at the water temperature of 8-10 DEG C in the fish pond; taking the fries with robust bodies; and controlling the time within 0.5-1.5 hours; (3) loading: loading the fries in a fish transportation water tank, wherein the temperature of water body in the fish transportation water tank is 8-10 DEG C; and after the fries are loaded, keeping the water level in the fish transportation water tank close to the top of the tank; and (4) transporting: controlling the water temperature to be 8-10 DEG C; transporting through a flowing water truck through aeration of an oxygen bottle; after a destination is arrived, mixing the fresh water which is gradually added into the pond with old water in the transportation water tank; adapting the fries to new environment and the temperature of the water body; and then transferring into a culture pond. By using the method, the megalobrama amblycephala adult fishes can be successfully fished, loaded and transported for a long distance at high density with high survival rate.

Description

technical field [0001] The invention relates to a method for fishing, loading and high-density transportation of bream seedlings, and belongs to the technical field of aquaculture. Background technique [0002] Megalobrama amblycephala, belonging to the class Teleost, Cyprinidae, Cyprinidae, Breaminae, and genus Bream, is now one of the main freshwater aquaculture species in my country. In the past 20 years, more than 20 provinces, municipalities, and autonomous regions in the country have introduced and cultured bream. At present, the output in the southern region accounts for more than 10% of the total output, and it has become one of the major freshwater fish species in ponds and cages in my country. , the economic benefit is very significant. Bream has a violent temper and is easily frightened. Compared with carp, crucian carp and other fish, it is not tolerant to hypoxia and transportation stress, causing injury, illness and death. Shi Zhaohong et al. (2006) applied fo...
