Low-carbon cycle fishery production method

Abstract

The invention relates to a low-carbon cycle fishery production method, which comprises the following steps: (1) building a soft-shelled turtle culture zone, a pearl culture zone and a river crab culture zone, wherein the area of the soft-shelled turtle culture zone accounts for 20-40 percent, the area of the pearl culture zone accounts for 20-30 percent, the area of the river crab culture zone accounts for 30-50 percent, and the area of a water intake canal accounts for 3-5 percent; (2) controlling the flow direction of a water body in each culture zone: making the water of the water intake canal enter the soft-shelled turtle culture zone, discharging the water of the soft-shelled turtle culture zone into the pearl culture zone, discharging the water of the pearl culture zone into the river crab culture zone, discharging the water of the river crab culture zone into the water intake canal and entering the soft-shelled turtle culture zone, and recycling. Realizing the discharging of the water of the three culture systems through machinery; and (3) carrying out respective culture modes of soft-shelled turtles, pearls and river crabs in the culture zones by the book. By adopting the low-carbon cycle fishery production method, soft-shelled turtle culture, pearl culture and river crab culture are combined together to achieve the goals of recycling the water bodies and energy, reducing the energy consumption and realizing low-carbon economy.

Description

technical field [0001] The invention relates to a fishery method, in particular to a low-carbon circular fishery production method. Background technique [0002] China is a big aquaculture country in the world, accounting for more than 65% of the world's total aquaculture volume. The variety of aquaculture, wide range, and high output are unmatched in the world. However, the aquaculture ecology is often affected by many factors. The energy consumption and cost of aquaculture remain high, and the aquaculture water body needs to be fully recycled. Soft-shelled turtle, scientific name Chinese soft-shelled turtle, commonly known as soft-shelled turtle, turtle, etc., is an oviparous amphibian reptile. It can reach 1 ton per mu per mu through artificial feeding, but the water discharged is mostly soy sauce-colored. For the cultivation of freshwater pearls, since pearl mussels feed on plankton, it is necessary to artificially fertilize the water quality and increase the amount of ...
