| Summary: | Data on distribution, stocks and biological parameters of commercial invertebrates and marine algae collected in the scientific diving survey in Aniva Bay in summer of 2024 are analyzed. Abundance and biomass of sea cucumber, gray sea urchin, and kelp laminaria in one of the aquaculture sites are evaluated and compared to the release of juveniles and planting material. Impact of aquaculture farming off the northern coast of the bay on natural populations of these species is discussed. Target volumes of commercial production were not achieved after 3 years of the species cultivation by pasturing method. Size and age composition of sea urchins in the aquaculture site did not match the parameters expected for the 4-year cycle of cultivation. No impact of pasture aquaculture on these commercial resources in the Aniva Bay is identified. |
