摘要

描述了连续2 - 3月(2013-2020年)在智利中北部海岸浮游生物样本中捕获的长鳃口鱼幼鱼的存在。其低丰度表现出年际变化和发生频率。它的地理分布最好是沿海地区。它在纵向上覆盖了整个采样区(距海岸1 ~ 20 nm)，在采样区最北端至30°20 s之间捕获标本。丰度最低的年份为负热异常年份(2017-2018)，最高的丰度主要出现在中性条件(2013-2015)。

On the presence of Branchiostoma elongatum juveniles (Cephalochordata: Branchiostomatidae) on the north-central coast of Chile

The presence of juvenile Branchiostoma elongatum captured in plankton samples from the north-central coast of Chile during February-March of consecutive years (2013-2020) is described. Its low abundance showed interannual variation as well as its frequency of occurrence. Its geographical distribution was preferably coastal. It covered the entire sampling area (1-20 nm from the coast) longitudinally, and specimens were captured between the extreme north of the sampling area and 30°20’S. The lowest abundances were found in years of negative thermal anomalies (2017-2018) and the highest mainly in neutral conditions (2013-2015).

期刊介绍： Latin American Journal of Aquatic Research- LAJAR is the continuation of the journal Investigaciones Marinas (1970-2007) and is published since 2008 by the Escuela de Ciencias del Mar, Facultad de Ciencias del Mar y Geografía of the Pontificia Universidad Católica de Valparaíso. LAJAR is an “Open Access” journal that publishes in English language, original research articles, reviews and short communications on aquatic science, which contain the results of research conducted in aquaculture or in oceanic and coastal marine waters of Latin America. The following topics are considered: Physical Oceanography, Chemical Oceanography, Marine Biogeochemistry, Marine Pollution and Toxicology, Marine Geology and Geophysics, Biological Oceanography, Fisheries and Aquaculture.
