Stages and conditions of catching market salmon from two agricultural ponds

Catching market salmon is the last stage of fish breeding in agricultural dual-purpose ponds and one of the most important stages, because the result of a breeding period is shown in it, and its correct and timely implementation has a great effect on the quality of fish offered and greater productivity. Lays. In order to catch fish from non-fisheries storage ponds in different breeding conditions, special considerations must be taken into account, which include:
– Considering that these pools are integrated, due to the difference in the ability of the fish to get food and as a result of their unbalanced growth, it is normal for the size difference to occur in the fish flock. Therefore, one of the fishing methods in such pools is gradual fishing. With this method, large fishes are caught and smaller fishes that are not of market size are given more opportunity to grow, while at the end of the period, the density of living mass in the pool decreases the risk of casualties. In this method, with brief feeding in the early morning, we collect the herd in a pool point with a net, then we catch them by satchuk. Then we return the large and market fish to the baskets and the smaller fish to the pool. In this way, the digitization operation is also applied relatively

Note: In case of gradual fishing, especially in large reservoirs, the pool can be divided into two parts before stocking with suitable nets or by building a wall with a height of 50 cm, and during fishing, the water levels can be raised to the limit. He lowered the height of the wall, then by collecting the net on one side of the wall, he caught the market fish and moved the smaller fish to the other side, and at the end, he re-drained the pool.

– After marketing, in order to catch the fish in a condition where most of the fish have the appropriate weight for the market, we prepare the necessary equipment such as fishing nets, baskets for transporting and supplying fish, labor, clean water for washing, ice, etc. Then, depending on the size of the fish and the quality of the product we want to offer to the market, we stop feeding between 24 and 48 hours before the fishing operation. It is better to catch fish in the early hours of the morning, for this purpose, we lower the water level of the pool to a height of 30-40 cm, gather the flock in one corner of the pool using a net, and catch the fish with the help of a sachuk with a net. . After catching, we put small and large fish in separate baskets in order to provide a good quality product and better marketing. Washing the caught fish with clean water followed by freezing is one of the things that will have a positive effect on the quality of the product

Note: In order to predict the final catch before the pool is drained and fished, a fishing pond can be built. In such a way that in front of the exit, which is also the end of the slope of the pool, there is a pond with appropriate dimensions and a net is installed at the exit. We build it in the form of a square or a channel (for example, length and width of 2 meters and a maximum depth of one meter for a pool with the release of 4000 pieces of salmon fry). In some cases, it is possible to select and prepare a part of the output storage water channel by cementing and installing a net as a fishing pond. At the end of the breeding period, after observing the basic conditions of fishing, such as cutting off the food before, without using fishing tools, it is enough to open the outlet of the pool floor and remove the net. The water of the pool along with the fish from the discharge outlet, the water of the pool passes through the net of the pond and goes to irrigate the farm, but the fish is collected and washed behind the net inside the catch pond. The final catch from the fishing ponds is also possible with the latter method
