Protecting Your Fish from Predators
Fish in ponds are especially vulnerable to predators and pond nets help keep them safe. The world's entire fish population is under threat from all kinds of predators but fish in the open sea have, at least, an entire ocean in which to seek refuge. Fish in ponds, however, are in a very vulnerable situation, enclosed as they are in a relatively small area. There are a number of methods to protect fish in ponds from predators and using pond nets is a simple, inexpensive option.
Koi and goldfish are among the most popular pond fish and can be quite expensive. Providing adequate pond protection is not just a matter of saving the fish or keeping the beauty of your pond. It's also a question of safeguarding your investment. Among the common predators that prey on pond fish are herons and cats. Some of these predators hunt only at night so fish pond protection must be round-the-clock.
Different ways have been developed to give pond fish adequate protection. Some are simple, practical ideas like locating the pond under a tree which shields it from the eyes of flying predators. In case there are no trees available, planting broad-leafed lotuses or lilies can provide some kind of cover. Another idea is to install a fence around the pond or build the pond with steep, sloping sides to discourage land predators from wading into the pond to feed on the fish. Still another method is to build the pond deep enough so the fish can swim to the bottom and not be visible from the surface. A similar idea is to build nooks and crannies in the pond where the fish can hide. A different type of protection involves installing decoys, some with motion detectors to act like scarecrows in an open field. The most common method, however, is still installing nets over or on the pond.
The more common pond netting device involves covering the entire pond with a single net. This prevents birds from diving down to snatch the fish and discourages land predators from wading into the pond. While this is certainly an effective deterrent against predators, it can mar the beauty of the pond. Single netting over the entire pond can also interfere with growth of water lilies and other plant vegetation. Moreover, single netting pond protection has to be custom made because pond sizes and shapes vary
A different type of pond netting involves smaller, circular interlocking nets which can be installed to float around the pond perimeter and throughout the pond. Spaces in between the interlocking nets leave room for lilies and other plants to grow. This type of pond netting system can be installed in any pond regardless of its size or shape.
The costs of the different methods of pond protection can vary. A pond owner's knowledge of the terrain and the environment can help him arrive at the best choice of pond protection. For simplicity and effectiveness though, installing pond nets is one of the best choices.
