Research finds fish to be on the increase in Lithuanian lakes2016-04-13
The results of studies carried out by the Nature Research Centre show that the fish stocks in Lithuanian lakes have increased significantly and their state has improved over the last five years. The reasons for that have been the toughening of responsibility for violations of the angling rules, the especially strengthened environmental controls and the ban on commercial fishing in inland waters (except for specialised fishing).
In 2011-2015, scientists from the Nature Research Centre carried out the research on fish communities in 284 lakes and 54 reservoirs of Lithuania. After summarising and comparing the indicators of 2011-2012, 2013-2014 and 2015 by the abundance and biomass of fish and the average weight of one fish in catches per standardised fishing effort, they found that those indicators had begun rising immediately after the amendment of relevant legal acts and the toughening of responsibility for violations of the fishing requirements as well as the strengthening of environmental controls on a proposal from the Ministry of Environment, i.e. from 2013. The situation improved even more after the ban on commercial fishing in inland waters was imposed in 2014.
Compared to 2011, in 2015 the total fish biomass in Lithuanian lakes increased by about one-and-a-half times and the average fish weight grew by 1.3 to 1.4 times.
