Solar Aeration Is the Answer To Increased Profit In Shrimp Farming


Solar aeration is the answer to modern shrimp farming. Modern shrimp farming really started in the “Reagan era.” Marine shrimp are farmed in dugouts, impoundments, ponds, raceways and tanks. Today over fifty countries have shrimp farms. With the increasing cost of electricity and the greenhouse gases it causes, all shrimp farms need solar aeration to replace the electrically operated aeration systems. Shrimp are no different than any other living creature; they need oxygen, clean water, and sunlight. They grow faster in warmer climates where you can sometimes produce three crops a year if you are near enough to the equator.

The leaders in shrimp farming in the Eastern Hemisphere are Thailand, Vietnam, Indonesia, India and China. Malaysia, Taiwan, Bangladesh, Sri Lanka, The Philippines, Australia and Myanmar also have large shrimp farming industries. Mexico, Belize, Ecuador and Brazil are the leading producers in the Western Hemisphere. There are shrimp farms in Honduras, Panama, Colombia, Guatemala, Venezuela, Nicaragua and Peru. The United States, Western Europe and Japan are the major shrimp importing nations. They have high-tech shrimp farming but their production is insignificant. Saudi Arabia and Iran produce the most farmed shrimp in the Middle East.

Shrimp farms use a one or two-phase production cycle. With the one-phase production cycle the shrimp spend a short period in acclimation tanks, then they are put directly into the growout ponds. Farms that use the two-phase production cycle stock juvenile shrimp from hatcheries in nursery ponds and several weeks latter transfer them to growout ponds. The shrimp need aeration in all phases of growth and solar aeration is best answer. Hatcheries sell two products: Nauplii, which are tiny, newly hatched, first stage larvae, and postlarvae that have already develop through the three larval stages. Good aeration produces clean water and healthy nauplii, postlarvae and shrimp. Solar aeration is the best investment for any shrimp farm and is available now.

Shrimp normally spawn at night and females may produce 50,000 to 1,000,000 eggs, which hatch in one day. The first larval stage is nauplii, which look like tiny aquatic spiders. The nauplii feed on their egg-yoke reserves for a couple of days. The nauplii then metamorphose into zoeae, which have feathery appendages. Zoeae feed on algae and formulated feeds for three to five days and then metamorphose into myses. Myses are just starting to look like shrimp and they feed on algae, formulated feeds and zooplankton. Myses metamorphose into postlarvae, which look like adult shrimp. Postlarvae feed on zooplankton, detritus and commercial feeds. From the day the eggs hatch till the postlarvae are ready to be moved to the farm takes about 25 days. To keep the product healthy, all larvae stages need adequate aeration, and solar aeration is the right answer to preserve our water quality and keep our earth green.

There are all sizes of hatcheries from home operations to medium and large-scale operations. All hatcheries need clean water and sunlight. It is impossible to maintain a healthy shrimp life cycle without aeration, which is, I repeat, best produced by solar power.

Shrimp farmers next move the animals from nursery ponds within 30 days to growout ponds. This move increases the survival rates of their juvenile shrimp and increases their profits. The greatest danger throughout the production cycle is virus problems, which can be avoided with sanitary conditions of clean water with adequate aeration. Shrimp farming, like any business, is about producing the highest quality product for the lowest cost possible, so that at the close of the business cycle there is a superior profit. Reducing electrical usage with solar aeration adds to a higher profit margin.
