Shrimp farming is slowly becoming a thriving economic activity. The demand for this fish species has been on the increase. Many consumers are also preferring those from a freshwater shrimp farm rather than wild waters. As such, more and more people are embracing this fish farming practice as it is proving to be extremely lucrative. However, many potential farmers are still skeptical taking up this business idea. Apart from the scaring start-up costs, many are just not sure how much the harvest they get will be. However, in case you are in such a situation, clear any doubts that your production will be on the lower side.
The harvest that your shrimp farm will yield definitely depends on a big number of factors, both internal and external factors. For instance, under the same climate, the amount of food given and possible presence of a predator could mean highly varied yields from similar ponds. For this reason, the production from Fresh water shrimp farming is gauged by a number of parameters such as:
- Stocking density: This refers to the number of juveniles per acre of water.
- Age of seed during stocking
- Rate of feeding fertilization (pounds per acre per year applied to the shrimp farm)
The type of feeding employed and whether artificial food supplements were added are also considered in analyzing the harvest from a farm.
The normal harvest to expect from your shrimp farm can be projected depending on the stocking density used. Here are the approximate harvests from differently stocked farms:
- Low-input culture (8,000 – 10,000 per acre): At such low densities, prawns are fed at a rate of 1,000 – 1,500 pounds per acre per year. In well aerated ponds, you can expect yields between 300 and 600 pounds per acre from this mode of shrimp farming.
- Semi-intensive stocking density (15,000 – 18,000 per acre) with constant aeration: The feeding rate at such a shrimp pond is 2,500 – 3,000. The yield here can vary between 400 to 800 pounds per acre per year.
- Intensive stocking density (more than 18,000 per acre): This warrants a feeding rate between 5,000 and 6,000 pounds per acre per year. Substrates are usually introduced to decreased mortality due to the dense stocking. This yields as high as 2,000 to 3,000 pounds per acre every year.
It is hard to ignore the fact that the supreme breeding conditions found in the experimental shrimp farming aren’t exactly what many farmers can manage in their farms. As a result, do not expect to get these experimental yields in your shrimp farm unless you are ready to work unusually hard. For instance, intensive stocking density farmers, on average, only manage a yield of about 1,200 – 2,000 pounds per acre. To ensure your harvest is at peak, always provide favorable conditions such as ensuring your pond water is safe and free from shrimp predators. In addition, a modern way of improving your shrimp farming harvests is by adding artificial supplements to your water.
