“…Some invertebrate larvae have been observed to alter their swimming behaviour in response to the presence and quality of food patches (Raby et al, 1994;Metaxas and Young, 1998b;Burdett-Coutts and Metaxas, 2004). In this study, although there was no significant correlation, a similar trend in vertical distribution between polychaete larvae and Chl a concentration was observed in several months ( fig.…”

Abe, H., Sato-Okoshi, W., Nishitani, G. and Endo, Y. 2014. Vertical distribution and migration of planktonic polychaete larvae in Onagawa Bay, north-eastern Japan. Memoirs of Museum Victoria 71: 1-9.The planktonic larvae of polychaetes are one of the most numerous and diverse groups in coastal zooplankton; however, little is known about their larval dynamics and the factors that affect their vertical distribution. We investigated the vertical distribution and migration of planktonic polychaete larvae in Onagawa Bay, north-eastern Japan, particularly focusing on the dominant spionid larvae. In total, 14 families of planktonic polychaete larvae and 14 species or genera of spionid larvae were identified during our study. Their density greatly fluctuated according to season and depth, with the polychaete larvae generally distributed in the lower layers of the water column. Furthermore, trends in vertical distribution of spionid larvae varied between species. In winter and spring, larvae of Polydora onagawaensis were the most prevalent, with a wide range in vertical distribution. In summer and autumn, larvae of Pseudopolydora achaeta and Prionospio spp. were the most prevalent spionid larvae and were primarily distributed in the lower layers of the water column. Trends in larval vertical distribution varied as a result of differences in adult habitat; these variations would enable the larvae to efficiently recruit into their appropriate adult habitats. Spionid larvae did not show diel vertical migration. Larvae of two spionid taxa, Pseudopolydora achaeta and Prionospio spp., exhibited tidal vertical migration, with larvae appearing to avoid dispersal by moving to slower-flowing deeper water during flood and ebb tides. Although many previous studies assume that, because of their limited swimming capacity, polychaete larvae are passively dispersed within the water column, this study indicates that polychaete larvae can control their vertical distribution to some extent, and this smallscale vertical migration may be important as a retention mechanism for polychaete larvae.

“…Probability levels given in parentheses sized larvae (veliconch and veliger larvae) (Bayne 1976, Mileikovski 1974, as well as to an aggregation resulting from a high food concentration near the surface (phytoplankton and DOM concentrations) (Maslov 2000). Larvae of scallop species are also known to migrate to foodrich depths (Raby et al 1994. This, however, is believed to be a partial explanation when looking at forces driving the vertical migration behaviour of scallop larvae .…”

The vertical distribution of veligers, pediveligers and post-larvae of the mussel Mytilus edulis L. was examined in Kandalakshsky Gulf (White Sea), Russia. Plankton samples showed that about 65% of all planktonic larvae were collected from a depth of 1.5 to 3 m. Maximum numbers of veligers were found at 3 m, immediately above the thermocline. The vertical distribution of veligers was stable throughout the study. The vertical distribution of pediveligers, however, varied over time. Pediveligers were mostly observed at 3 m before settlement peaked while they migrated closer to the water surface (1.5 m) during the settlement period. Pediveliger concentrations were correlated positively with small phytoplanktonic cell (<150 µm) and dissolved organic matter concentrations before settlement peaked. Both factors were correlated negatively with pediveliger concentrations during the settlement period. Newly settled post-larvae mainly colonized settlement panels situated at 1.5 m below the water surface (ca 70% of total post-larvae abundance). These results support the hypothesis that planktonic larvae of M. edulis change their vertical distribution in relation to larval stages, which in turn, increases settlement success.

“…Although several studies have highlighted the role of clines in the aggregation of zooplankters and their food, creating biological hotspots (Raby et al 1994, Grønkjaer & Wieland 1997, Woodson & McManus 2007, Tapia et al 2010, Woodson et al 2012), a strong halocline (i.e., pycnocline) occurred throughout the study at both stations, and this oceanographic feature did not affect the feeding success of fish larvae. Pycnoclines may provide optimal conditions for phytoplankton growth and can be regions of enhanced phytoplankton biomass as a result of both passive and active organism responses (McManus & Woodson 2012).…”

Resumen.-Es ampliamente reconocida la utilización de estuarios como zonas de crianza para peces e invertebrados, pero el éxito en la explotación de los recursos variará entre las especies residentes del estuario y las oportunistas. Se estudió la distribución y dieta de larvas de Myxodes viridis (Pisces, Clinidae) en 2 localidades del estuario de Bahía Corral (estuarioarriba y estuario-abajo), uno de los estuarios más grandes del sur de Chile, durante la primavera austral de 2009 a 3 profundidades (superficie, picnoclina, profundo) durante la fase llenante y vaciante de 4 ciclos mareales. Las larvas fueron recolectadas principalmente en la estación estuario-abajo durante fase vaciante. La incidencia alimentaria también fue mayor en la fase vaciante; las larvas cambiaron de omnivoría a carnivoría a medida que se desarrollaban, depredando principalmente sobre nauplii y copepoditos calanoideos. Aunque el éxito alimentario fue similar para cada estado de desarrollo en la columna de agua, la dieta de larvas en preflexión y flexión estuvo basada en diferentes ítems presa dentro de los primeros 3-4 m de la columna de agua (superficie y picnoclina) con respecto de aguas más profundas (7-10 m, cerca del fondo). Esto sugiere que la picnoclina pudiera afectar la composición de la dieta de larvas pequeñas de M. viridis, pero no el tamaño, número o volumen de presas ingeridas. Además, ya que el forrajeo está basado predominantemente en diferentes estados de desarrollo de copépodos, las larvas que emergen durante vaciante pueden incrementar la advección fuera del estuario hacia zonas costeras cercanas, indicando que esta especie no es un usuario frecuente del estuario durante su desarrollo larval. Palabras clave: Myxodes viridis, ictioplancton, éxito alimentario, Bahía CorralAbstract.-The utilization of estuaries as nursery zones for fish and invertebrates is widely known, but differences in the success of resource exploitation vary between resident and opportunistic estuarine species. The distribution and diet of larval Myxodes viridis (Pisces, Clinidae) were studied at 2 locations (up-estuary and down-estuary) in the Corral Bay estuary, one of the largest estuaries in southern Chile, during the austral spring 2009 at 3 depths (surface, pycnocline, deep) during the flood and ebb of 4 tidal cycles. Larvae were collected mostly at the down-estuary station during the ebb phase. Feeding incidence was also greater during the ebb phase; larvae changed from omnivory to carnivory as they developed, predating mainly on nauplii and calanoid copepodites. Although the feeding success was similar for each developmental stage along the water column, diet of preflexion and flexion larvae was different in the first 3-4 m depth (surface and pycnocline) in relation to deeper waters (7-10 m depth, near to the bottom). This suggests that the pycnocline may affect the composition of the diet of small, larval M. viridis but not the size, number or volume of ingested prey. Additionally, because foraging is predominantly based on the different life ...
