Fishing, Especially in slightly more distant ponds, has in recent years decreased sharply. This means that the number of fish has become more than is reasonable in view of the business asset. If no measures are taken with targeted reduction fishing, the stock is formed by so -called 'thousand brothers' who are shrunk and stays in the plant around ten centimeters.
Thousand brothers are formed due to great population density. A year with fry at first eats herbplankton and reaches a size around 7-10 cm. Then they switch to living on bottom animals where the supply is smaller and the fry suffers from nutritional deficiencies. If there are also missing predatory fish, as galls in the stock, is the problem even greater.
Perch and char, But also trout, are populations that can form stocks with thousand brothers.
In Långå Fisheries Area, reduction fishing and "regrouping" is a way to solve the problem. At the same time, the requirement for conservation and the use of locally embossed Ädelfisks is met with multi -thousand pedestrian pedigree. The genealogy that extends to the centuries after the inland ice. In these tracts for approximately 8 000 years ago!
Långåfisket has genetic stems of the salmon fish trout, char, Harr and SIK that received their character traits through local embossing for millennia. The Fisheries Association considers the four noble fishermen as a unique asset. For more than three hundred years, the fishing rights owners have understood the value of preserving and nurturing this natural resource as an indispensable asset. So it still is and will be in the future. Preserve, Care and use are Långåfisket's focus areas and responsibilities.

In recent years the problem has been investigated through special sample fish with nets. Margareta Selin-Ring and Torsten Kristoffersson have carried out the work in some selected ponds with trout. The results are reported and documented. The effort is valuable and appreciated. In addition to knowledge of the problem, catches have given measurable effects. By reducing the stocks, increased K-factor is noted, thus the ratio of the weight and length of the fish. The trout gets larger and the fat content increases as well as the delicate taste.

The conclusion is that the method works and is effective. It can be performed with good security, under control, With measurable results. The action meets the requirements for appropriate fishery care with good ethics.

Admittedly, natural overproduction of fish fry is a problem, But at the same time an asset that can replace the need for support cultivation for release in water that has the capacity to keep larger stocks. For five years the main strategy in Långåfisket is that the original fish species should be preserved thanks to natural reproduction without cultivation.

Gentle capture and late regrouping fish fry is another functioning and acceptable method for biodiversity that meets strategy and quality requirements within Långå FVO. The method is a way to fulfill the authenticity of the long -term fishing.
