Can horseshoe crabs be artificially farmed? A feasibility analysis of horseshoe crab farming

The horseshoe crab is a very ancient creature with high medicinal value, and it is also an endangered species. Horseshoe crab generally refers to the Chinese horseshoe crab (Tachypleus tridentatus). Because of its wide range of uses, many people want to farm it, so can the Chinese horseshoe crab be artificially farmed? If so, how should it be raised? Now follow along with the editor to read the content below and solve the puzzle in your mind.

1. Can horseshoe crabs be artificially farmed?

At present, horseshoe crabs still cannot be artificially farmed; they can only be kept temporarily, that is, raised for a period of time. If they are artificially kept for too long, they will show symptoms of anemia and eventually die, which means the longest keeping time is about one year. If large-scale artificial farming is to be carried out, what is most lacking now is farming technology, so farming techniques still need to be continuously improved before true artificial farming of horseshoe crabs can be achieved.

2. Preparation of the farming pond

Since horseshoe crabs can be kept temporarily, let us briefly understand the temporary keeping techniques for the Chinese horseshoe crab. Generally, temporary keeping of horseshoe crabs is divided into two types: indoor keeping and outdoor keeping. Indoor farming ponds are generally cement ponds built with bricks and then plastered with cement. After the cement pond is built, a layer of river sand should be spread on the bottom of the pond, and an aerator and seawater injection equipment should be installed. Outdoor farming ponds are generally earthen ponds. Their cost is relatively much lower than indoor keeping, and water gate valves for inlet and outlet also need to be installed to facilitate water intake and drainage.

3. Preparation of bait

Horseshoe crabs have relatively high requirements for feed, so when farming them, we must first prepare the feed needed by horseshoe crabs. Horseshoe crabs mainly feed on small miscellaneous fish, oysters, and razor clams (Sinonovacula constricta). Among these, it is best to use oysters and razor clams for feeding, as this is more in line with the living habits of horseshoe crabs. Of course, live bait costs too much, so frozen feed is also used, generally mainly small miscellaneous fish. However, when using frozen feed, special attention must be paid to one point: after the feed is thawed, it must be rinsed clean with seawater before feeding. If the fish are too large, they also need to be chopped up.

4. Feeding techniques

Raising horseshoe crabs is really not easy, and great importance is attached to farming techniques, so one must be very careful. Horseshoe crabs are very sensitive to water temperature, which directly affects their feeding. Generally, when the water temperature is between 20 and 25 degrees, horseshoe crabs have a very good appetite, and at this time our feeding amount should be appropriately increased. But if the temperature drops, we need to appropriately reduce the feeding amount. Also, after horseshoe crabs finish eating, the remaining food residue should be cleaned up in time to avoid polluting the water quality. Finally, remember to change the water every day, generally in the morning, and the farming pond needs to be cleaned and disinfected once every week.

So far, horseshoe crabs still cannot be artificially farmed. As for whether they can be farmed in the future, that will depend on the development and progress of farming technology later. Well, that is all for today's introduction about horseshoe crabs. Thank you for reading.
