Abstract

The aim of the present study is to assess the spatial distribution and habitat preferences of the cryptobenthic fish assemblages around the Gökçeada Island, where no study on these species were previously conducted. A total of 51 quadrats of 1 m2 were applied to 12 sites at the depths of 0–15 m in June, August and October 2017. The cryptobenthic fishes were studied by anaesthetic sampling. A total of 187 cryptobenthic fish specimens of 23 species were observed and 111 of them were obtained. The results showed that the 0–1 m depth zone is dominated by the blennies and shows greater density than 1–15 depth zone, where gobies are outnumbered. The average abundance of cryptobenthic fish was 3.7 individuals/m2 and Gobius incognitus represented 21% of all individuals. Among the studied species, Parablennius incognitus and P. zvonimiri were only found within 0–1 m, preferring rocky substrates with short thallus algae. Coryphoblennius galerita was found on bare rocky surfaces, mostly in 0–1 m depth interval and Microlipophrys canevae preferred rocky surfaces with short thallus algae covers in as well very shallow waters. While Lepadogasterlepadogaster preferred the depths between 3–5 m, L. candolii was observed in a wider depth range (1 and 6 m).

Gökçeada岛(北爱琴海)周围的隐栖鱼类组合的栖息地偏好和空间分布

摘要

本研究的目的是评估Gökçeada岛周围的隐栖鱼类组合的空间分布和生境偏好,此前尚未对这些物种进行过研究。于2017年6月,8月和10月,在0至15 m深度的12个地点共施以51个1 m 2的方方动物。通过麻醉采样研究了隐栖鱼类。总共观察到187种23种底栖鱼类标本,获得了111种。结果表明,0-1m深度带主要由绒布构成,密度大于1-15个深度的虾虎鱼。隐栖鱼类的平均丰度为3.7个/ m 2戈比乌斯隐身占所有个人的21%。在所研究的物种中,Parablennius incognitusP. zvonimiri仅发现在0-1 m范围内,偏爱具有短th藻的岩石基质。Coryphoblennius galerita被发现在裸露的岩石表面上,大多在0-1 m的深度范围内,而Microlipophrys可以在较浅的水域中避开藻类覆盖层短的首选岩石表面。虽然Lepadogaster lepadogaster首选深度在3–5 m之间,在更广的深度范围(1和6 m)中观察到了candolii L.。
