Benefits of technology

This patented technology improves on traditional methods for creating bags used by fishermakers during their production process. It achieves these benefits through controlling how many seeds (prorocyste) each bag contains, which helps them grow faster without losing too much space or getting damaged from being kept outdoors when they're closed at night). Additionally, it uses algae that help keep water clean while keeping certain crops alive also makes seafood more accessible with fewer harmful chemical substances than other ways. Overall, this innovation enhance the quality of food produced by farming oceanic organisms like prawn shellfishes.

Problems solved by technology

This patented technical problem addressed by the inventor relates to improving the efficiency with which crops can be grown on riverside areas without causing harm or reducing their quality due to excessive water usage during harvest periods.

Embodiment 1

[0039] The invention discloses a method for cultivating river crabs and crabs in different positions in the same pond for culturing crayfish in different positions. The steps of the polyculture method are as follows:

[0040] (1) Pond design (see figure 1 shown)

[0041] (1.1) This breeding mode is mainly suitable for larger ponds, the pond is 50m wide and 150m long;

[0042] (1.2) The bottom of the pond is surrounded by pond side ditch 10, the width of the pond side ditch is 4m, the depth is 1.2m, 0.6m deeper than the central platform 20, and the highest water depth of the central platform is 0.8m;

[0043] (1.3) central platform accounts for 70% of whole pond area, is mainly used for cultivating river crabs, and the center of central platform is provided with platform deep ditch 30 about depth 0.5m, is used for river crab early stage temporary cultivation, and platform deep ditch accounts for 10% of pond total area About 15%, the pond ditch accounts for 20% of the entire p...

Abstract

The invention discloses a method for different-position mixed lobster breeding in the same river adult crab aquaculture pond. The mixing breeding method comprises the steps of pond design, juvenile crab capture and stocking, juvenile lobster stocking and capture, lobster density control, feeding management, daily management and river crab capture and marketing. The method is characterized in pond design, juvenile procambarus clarkia density control, lobster larva supplementing at regular intervals and removal of lobsters in a river crab breeding area. By using the ecological breeding method, the yield of lobsters in deep ditches around the pond in per mu of pond is 35-50 Kg/mu, the adult crab yield of the river crab breeding area is about 70 Kg/mu, and the procambarus clarkia yield is about 10 Kg/mu. On the premise that the adult crab breeding cost is not increased basically, the net profit per mu of the river adult crab aquaculture pond is increased by 500-1000 yuan, the culture benefit is increased, and the risk of river crab single variety breeding is reduced.
