How about raising crabs under photovoltaic panels

Based on these studies, it can be initially inferred that photovoltaic panel shading is beneficial for shade-loving species such as Chinese mitten crabs (Eriocheir sinensis), catfish (Pelteobagrus fulvidraco), and shrimp (Litopenaeus vannamei).

In conclusion, PV panels could promote growth performance and amino acid nutrition of crabs. However, the PV panels had a few negative influences on the fatty acid composition and tissue.

In particular, photovoltaic panels have a blocking effect on sunlight, which changes the breeding environment and is conducive to the growth of high-quality varieties such as blue crabs, sand shrimps, soft-shelled turtles, river crabs, yellow catfish, and sand pond snakeheads.

meat yield of male crabs in the PV group signiﬁcantly increases. In addition, the moisture of muscles, hepatopancreas, and testes in the PV group has signiﬁcantly increased, and the total .

The crab ponds, home to prized Chinese mitten crabs (also known as Shanghai hairy crabs), are now doubling as solar power stations. Zhang Jun, a local crab farmer, has been experimenting with this new idea. "I've been raising crabs on about 200 mu (around 13.33 hectares) of my pond this year," he said.

6 FAQs about [How about raising crabs under photovoltaic panels]

Can crab ponds be used as solar power stations?

Lvuhua Town on the island is leading the way in adopting the combined "fisheries-solar" approach. The crab ponds, home to prized Chinese mitten crabs (also known as Shanghai hairy crabs), are now doubling as solar power stations. Zhang Jun, a local crab farmer, has been experimenting with this new idea.

Do solar panels reduce crab mortality?

Notably, after solar panels were installed, Zhang noticed a significant drop in the crab mortality rate. He explained that the panels serve as natural sources of shade, cooling the water during the hot summer months and creating a healthier environment for the crabs.

How much electricity does Shanghai crab pond use?

According to the State Grid Shanghai Municipal Electric Power Company, organizers secured 10 million kWh of clean electricity for the event, a quarter of that coming from solar panels in the crab ponds, ensuring that the venue runs sustainably throughout its duration.

Could solar power save fish & shrimp?

The fish and shrimp are expected to thrive. The 70MW fishery PV project. Farms where fish and algae thrive under solar panels might have secured their place in a future powered by renewable energy.

Can a solar plant atop a fish pond in China?

Concord New Energy, a Chinese company that specializes in wind and solar power project development and operation, has installed a 70 MW solar plant atop a fish pond in an industrial park in Cangzhou, China’s Hebei region, according to an initial report from PV Magazine.

How much electricity does a floating solar panel generate?

The floating solar panels generate 45.76 million kWh of electricity annually. According to the developer, China Huadian Corporation Ltd., the output is equivalent to saving 14,000 tonnes of coal each year and reducing carbon dioxide emissions by 39,000 tonnes annually.
