Influence of some variables on zooplankton capture methods in an upwelling area (Galicia, NW Spain)

Abstract

In this study, zooplankton composition and abundance data from a sampling carried out in three stations of the Ría of Vigo and adjacent shelf are compared. Sampling was carried out during daytime and nighttime using different types of mesh (200 µm and 500 µm), as well as different types of tow (horizontal and oblique). Copepoda were the dominant planktonic group in most samplings, reaching percentages of up to 88.6%. Zooplankton abundance was greater in tows carried out with 200 µm meshes (10 935± 10 022 ind/m3) than with 500 µm meshes (431± 355 ind/m3). Greater abundances were obtained with the oblique tow (6195± 9206 ind/m3) than with the horizontal tow (5171± 8583 ind/m3). On the other hand, abundances obtained in the nighttime sampling (3243± 3736 ind/rn3) are in some cases higher than those obtained during the daytime sampling (2415± 2402 ind/m3).

Se comparan los datos de composición y abundancia de zooplancton de muestreos realizados en tres estaciones de la Ría de Vigo, utilizando diferentes tipos de malla (200 µm y 500 µm) y modalidades de arrastre (horizontal y oblicuo) en horario nocturno y diurno. Los copépodos fueron el grupo zooplanctónico dominante en la mayoría de los muestreos, alcanzando porcentajes de hasta el 88.6%. La abunancia de zooplancton fue mayor en los arrastres realizados con mallas de 200 µm (10 935± 10 022 ind/m3) que con 500 µm (431 ± 355 ind/m3). En el arrastre oblicuo se obtienen abundancias mayores (6195 ± 9206 ind/m3) que en el horizontal (5171 ± 8583 ind/m3). Por otra parte, las abundancias obtenidas en el muestreo nocturno (3243 ± 3736 ind/m3) son, de forma general, más elevadas que las diurnas (2415 ± 2402 ind/m3).
