摘要

本研究评估了三鳍Helcogrammoides chilensis（雷公藤科）预定居鱼类幼虫的游泳行为与当地环境条件的关系。2014年和2016年南夏季，在智利中部的岩礁上记录了幼虫聚集，以描述它们的游泳行为（即孤独、浅水、上学），并将其与现场水温、风应力、风速和湍流联系起来。2014年，只有风引起的湍流和2016年的海水温度和风应力影响了浅滩和孤立行为。上学行为不受任何环境变量的影响。鱼类幼虫的原位游泳行为很少被研究，这项工作提出了一种非侵入性的原位方法来研究鱼类幼虫的行为。

Presettlement schooling behaviour of a rocky fish in a shallow area. Is it related to local environmental conditions?

This study evaluates the swimming behaviour of pre-settled fish larvae of the triplefin Helcogrammoides chilensis (Tripterygiidae) in relation to local environmental conditions. Larval aggregations were recorded on rocky reefs off central Chile during the austral summer of 2014 and 2016 to describe their swimming behaviour (i.e. solitary, shoaling, schooling) and relate it to in situ water temperature, wind stress, wind speed and turbulence. Shoaling and solitary behaviour were influenced only by wind-induced turbulence in 2014 and by seawater temperature and wind stress in 2016. Schooling behaviour was not influenced by any of the environmental variables. In situ swimming behaviour of fish larvae has been little investigated, and this work proposes a non-invasive in situ methodology for studying fish larval behaviour.
