Pelagic larvae of benthic invertebrates of the Vostok Bay, peter the great bay, Sea of Japan: Composition, phenology, and population dynamics

The distribution of cirripede larvae (Cirripedia: Thoracica) in the Amursky and Ussuriisky bays of the Sea of Japan

“…In the zone of variable immersion, C. dalli was found at all of the surveyed mooring facilities of Amursky Bay [8]. However, in recent years in brackish and polluted areas, this species has been partially eliminated from the lower littoral zone by the more evribiont A. improvisus [18].…”

“…For example, in the Alekseev Bay, Popov Island, the peak abundance of B. rostratus larvae also occurred in October in [1988][1989][1990]; the maximum density, 400 ind./m 3 , was recorded in 1989 [10]. In the Vostok Bay in 1999-2006, the October maximum density of larvae of B. rostratus was 164-300 ind./m 3 [18].…”

“…We should note that in Nakhodka Bay, the density of larvae of A. improvisus was the least in Cirripedia and did not exceed 18 ind./m 3 in 1995 [11], indicating that in the 1990s this species had just started to spread in the northern part of Peter the Great Bay. In the Vostok Bay, the maximum density of A. improvisus larvae reached 100 ind./m 3 in 1999-2006 [18].…”

“…In Nakhodka Bay, the larvae of this species occurred from June to August, with a density of less than 20 ind./m 3 in 1995 [11]. At the same time, in Vostok Bay, C. dalli was one of the dominant species from 1999 to 2006, with the maximum larval density reaching 450 ind./m 3 [18].…”

“…In 1995, a high density of larvae of this species, more than 500 ind./m 3 , was recorded in late September in the innermost part of Nakhodka Bay [11]. In Vostok Bay in 1999-2006, H. hesperius was one of the dominant species in the plankton, reaching a density of 220-400 ind./m 3 in September-October [18].…”
