Scientists explain the massive release of herring on Sakhalin
VNIRO scientists explained the massive release of herring on the coast of the Kholmsky District of the Sakhalin Region. This is common in post-spawning fish.
According to the press service of the Pacific branch of the All-Russian Research Institute of Fisheries and Oceanography, unlike Pacific salmon, far from all herring dies after spawning - this is due to its overcrowding. Sakhalin-Hokkaid herring spawns along the inhabited coast of Sakhalin, so residents pay attention to this.
Previously, the head of Ekovahta Sakhalin Dmitry Lisitsyn in his Instagram posted a photo of a huge amount of herring caught on the shore.
“So far, signs of recovery in this previously undermined population persist. Let's see what happens next, ”he wrote.
According to her data from VNIRO, in 2020 diving survey made it possible to estimate the stock of Sakhalin-Hokkaida herring at 35,5 thousand tons, which is much more than the estimates of 2018. Six thousand tons of herring can be harvested in 2022 without damage to the population.
