“…Therefore, in contrast to what was presented by other authors (Cushing, 1990;Reynalte-Tataje et al, 2011), the food offered, such as macrozooplankton and benthonic organisms, does not appear to be the main reason that larvae in more advanced development stages are occupying the pool environment; no differences were found between the abundance of these organisms in both analyzed environments. Apparently, with the development of sensorial and swimming capacities, the larvae prefer the pool environments.…”

This study aimed to evaluate the importance of two environments situated in the main channel of the Peixe River (a tributary of the upper Uruguay River) on fish reproduction and initial growth. Ichthyoplankton, macrozooplankton, and zoobenthos collections were taken on a monthly basis from October 2011 to March 2012, sampling a rapids and a pool environment. The instrument used for the capture of the ichthyoplankton in both environments was a light trap. In total, 795 eggs and 274 larvae were captured. The species that presented higher abundance and occurrence frequency out of the total captured in both environments were Leporinus obtusidens, Bryconamericus iheringii, and Bryconamericus stramineus. The evaluation of the feeding activity reveals a major repletion degree of the larvae in more advanced stages in the pool. The pool environment presented a higher abundance of larvae in more advanced development stages. We conclude that the channel of the Peixe River is important for the reproduction and initial growth of fish and that each river environment seems to fulfill a different role in the life cycle of the ichthyoplankton community.Este trabalho avaliou a importância de dois ambientes situados no canal principal do rio do Peixe (afluente do alto rio Uruguai) na reprodução e crescimento inicial dos peixes. As coletas de ictioplâncton, macrozooplâncton e zoobentos foram realizadas mensalmente no período de outubro de 2011 a março de 2012, amostrando um ambiente de corredeira e um ambiente de poço. O instrumento utilizado para a captura do ictioplâncton nos dois ambientes foi a armadilha luminosa. No total, foram capturados 795 ovos e 274 larvas. As espécies que apresentaram maior abundância e frequência de ocorrência do total capturado nos dois ambientes foram Leporinus obtusidens, Bryconamericus iheringii e Bryconamericus stramineus. A avaliação da atividade alimentar revela um maior grau de repleção das larvas em estágios mais avançados no ambiente de poço. O ambiente de poço apresentou uma maior abundância de larvas nos estágios mais avançados de desenvolvimento. Conclui-se que o canal do rio do Peixe é importante para a reprodução e crescimento inicial de peixes e que cada ambiente do rio parece cumprir um papel diferente no ciclo de vida da comunidade ictioplanctônica.

“…Hake recruits were detected from February to April 2004 in the surveys conducted off the Balearic Islands Thus, different environmental conditions could alter the bottom-up forcing of the system and the ocean productivity, which would produce matches and mismatches between zooplankton production and fish larvae (Cushing 1990). However, more extensive and inter-annual studies must be performed to test whether the warmer temperatures in 2003 compared to 2002 might have resulted in a more successful recruitment in 2004 than in 2003.…”

Oxygen (δ 18 O) and carbon (δ 13 C) isotope ratios in sagittal otoliths were analysed in recruits and juveniles of European hake Merluccius merluccius L. caught in the northwest (Sóller, SO) and south (Cabrera, CA) of the Island of Mallorca (western Mediterranean) over 2 consecutive years (2003 and 2004). The analytical method used allowed data to be gathered on both environmental and trophic conditions experienced by fish during the pelagic early life stages (registered in the composition of the inner part of the otolith, core area) and the demersal aggregations of recruits (at the otolith edge). Results on the seasonal variation of oxygen isotope signatures at the edge of fish otoliths captured in SO and CA indicated different vertical migration behaviours of hake between the bottom and the thermocline. δ 13 C showed a clear ontogenetic pattern between the core area and the edge, confirming the differences in diet from the early stages to post-recruits. The seasonal analysis of δ 13 C data from the otolith edge indicated that fish from the early stages in June 2003 encountered poorer trophic resources, which resulted in poor fish condition and subsequent poorer recruitment. The estimated temperature from the core area of otoliths showed lower temperature regimes in the 2002 hatching season compared to the 2003 hatching season, which could be a possible explanation for the observed differences in success of subsequent recruitment.

“…For instance, if survival is governed by predation, larger larvae should be less susceptible to predation (the 'bigger is better' hypothesis; Miller et al 1988), while faster-growing larvae should be available to predators for a shorter period of time before metamorphosis to the juvenile stage (the 'stage duration' hypothesis; Anderson 1988, Cushing 1990). In the case where starvation is the principal cause of mortality, larger and faster-growing larvae are expected to exhibit the highest feeding rates, and to be less sensitive to starvation (Beyer & Laurence 1980, Rosenberg & Haugen 1982.…”

This suggests that the latter larvae exploited the ETM during a major part of their early life but were expulsed and experienced poorer growth conditions during the latter part of the summer.Size-selective or growth-dependent mortality is frequently interpreted in terms of predation through the 'bigger is better' hypothesis (Miller et al 1988), or the 'stage-duration' hypothesis (Anderson 1988, Cushing 1990, respectively.

We investigated the link between hatch date, growth trajectory, estuarine retention and survival of rainbow smelt larvae Osmerus mordax in the St. Lawrence Middle Estuary. Young smelt were collected over their entire distributional range across the salinity gradient of the Middle Estuary (0 to 25 psu) during 2 growing seasons. Individual growth trajectories and hatch-date distributions were reconstructed from otolith microstructure. High abundances of larvae were observed in the upstream region (0 to 10 psu) corresponding to the estuarine turbidity maximum (ETM). Larval rainbow smelt hatched in May during a period of 26 to 27 d, and mortality rates were variable among hatch dates. These variations were related to the feeding conditions experienced by first-feeding larvae (3 to 5 d after hatching) that fluctuated from day to day according to a predictable cycle of 15 d associated with photoperiod and tide. Comparison of growth trajectories of larvae at various ages indicated that older individuals, i.e. survivors, grew faster. Furthermore, smelt larvae collected within the ETM exhibited significantly higher growth rates than those sampled in the downstream area of the Middle Estuary, suggesting that larvae collected in the latter region represented dispersal from the ETM. We concluded that inter-annual variations in year-class strength might not be generally affected by early starvation, as larvae will experience recurrently good, medium and bad first-feeding conditions each year because of the length of the hatching period. However, any factor that reduces growth rate during the larval stage, including parasitism, has the potential to affect interannual variability in year-class strength.KEY WORDS: Hatch date · Growth rate · Survival · Estuarine turbidity maximum · Otolith microstructure · Rainbow smelt larvae 203: 233-245, 2000 and silversides Menidia beryllina (Gleason & Bengtson 1996) have been reported. Resale or republication not permitted without written consent of the publisherMar Ecol Prog SerThe different causes of mortality during the early life history of fishes implies different selective processes acting on the phenotype within generations (Houde 1997). For instance, if survival is governed by predation, larger larvae should be less susceptible to predation (the 'bigger is better' hypothesis; Miller et al. 1988), while faster-growing larvae should be available to predators for a shorter period of time before metamorphosis to the juvenile stage (the 'stage duration' hypothesis; Anderson 1988, Cushing 1990). In the case where starvation is the principal cause of mortality, larger and faster-growing larvae are expected to exhibit the highest feeding rates, and to be less sensitive to starvation (Beyer & Laurence 1980, Rosenberg & Haugen 1982. Finally, if dispersion is mainly responsible for mortality, larger and faster-growing larvae should exhibit better swimming capabilities for retention in favourable nursery areas. However, it is unlikely that only 1 mechanism regulates mortality (Legg...
