Predatory fish protects the fish from a mass death

In Lithuanian lakes and rivers in recent times massively dying fish, so look for an answer to the question, what is the reason? Panevezys environmentalists still waiting for the results of the study. One of the most frequent explanations is the lack of oxygen. However, the ichthyologist Linas Logic does not consider this a major problem. He spoke about another phenomenon, which in the summer can cause death of fish.

GRYNAS.lt wrote about dead fish found near the Nevėžis panevėžys. She was noticed on section of the river is 3 km long. While specialists have no answer about the cause of death of fish.

Last week the Inspectorate of the protection of wildlife under the Department of environmental protection Panevezys region Alfredas Brave said that, most likely, the fish died due to hit the river pollution. A study of water samples is not yet complete.

By estimates of inspectors, the nature of the damage for the sum more than 100 000 litas.

Senior researcher Marine colaboratorii Center for scientific research L. Lois believes that the reason for the death of the fish in hot days – rotting seaweed. But it’s not about Panevezys history.

“I think it may be a high probability of toxins. Are substances that are released during the decomposition of toxic algae. It is rather segoviano with the fact that water is rich in nutrients. This mainly concerns nitrogen and phosphorus. This causes rapid reproduction and growth of algae. The process takes place under high temperature,” suggested the scientist, noting that to establish the presence of toxins in water is difficult because all traces of them soon. The interviewee did not feel that the cause of death of fish – the lack of oxygen.

The question of which fish are more susceptible to poisoning by the toxins, Lois noted that pike, perch and roach. And carp, he said, a lot tougher.

How to help the fish in these conditions? The scientist said that there is no quick solution, but you should try to keep to the rivers and lakes gets as little pollution resulting in algal blooms.

Lois explained that algae, which decompose and adversely affect the fish, the less there where to catch more predatory fish: “If in a reservoir there are many predatory fishes, the situation is much better. Predatory fish eat small fish. Small fish eat the zooplankton. As predators eat small fish, zooplankton is more and it eats algae. In this case, the water is transparent and less blooms.”
