Fish Farming: Natural Friends and Enemies
The Natural Friends & Enemies Of The DIY Fish Farmer
By Vin Haynes
In and around a natural pond, there are a variety of different species living together. In a DIY fish farm, it's no different. Some of these critters are harmful to your fish, others are helpful. But, which are which? Figuring that out and maintaining a healthy balance is a fish farmers priority.
There are more creatures than you can imagine that will find a home in and around your fish farm. Rearing ponds will be especially attractive when they contain ova or young fish. It's important, then for the DIY fish farmer to get acquainted with what's in his water.
Insects, both in larval and adult stages, are some of the worst enemies in the water. Some will attack the vulnerable ova even before they hatch, still others will prey on the tiny new alverins.
Any indication that an insect attack is occurring should be taken seriously. It's important to deal with any infestation as quickly as possible for the health of your fish. Your local county extension or other agency can give you information about how to deal with native insects.
Not only do your fish need protection from insects, but also from birds. Even if you don't see any threatening species now, you will once those fish are being raised. Herons and Kingfisher are just two of the bird species that are well-known for raiding fish farms.
Birds in general are quite smart and very determined. They really want the fish and they'll do whatever they can to get at them. Keeping these hungry predators from eating their fill will be a major concern.
One way to keep the birds out of your fish stock is to use protective netting. The net should be of fine mesh and will cover the entire body of water. It should be strongly staked and anchored to the shoreline. Check the netting often for tears or holes and repair them immediately.
