The Kronotsky Nature Reserve has reported the results of its field season, revealing a positive trend in the gray whale population in the northern part of Kronotsky Bay. For half a year, researchers studied various aspects of the lives of these endangered species.
Observations were conducted both from the shore and from boats. The first whales were spotted in the bay early this year, in late April. Over the entire study period, 96 individuals were recorded, one less than in the previous season. However, this year, specialists noted an increase in the number of calves. They managed to record 16 calves, which is an excellent indicator. Last year, there were only 12 calves.
About 20 whales spent the entire feeding season in Kamchatka. These were mainly calves and juveniles. They fed until early November. Scientists noted the well-fed condition of the animals, indicating a sufficient food supply.
The report states that in the summer, the northern Pacific Ocean has food for everyone, including marine mammals. The protected waters of the Kronotsky Nature Reserve are relatively small, just 3 nautical miles wide. However, it is here that endangered sea otters live year-round, and gray whales prefer to spend their feeding season.
Scientists also found that the population of sea otters in the bay is stable. Their numbers are estimated at 400-450 individuals.
During the surveys, specialists used an unmanned aerial vehicle.
Next year, research on marine mammals in the waters of the Kronotsky Nature Reserve will continue.
