“…The Ria Formosa is a highly productive mesotidal lagoon system in the South Coast of Portugal characterized by a seaward belt of dunes protecting a system of salt marshes, subtidal channels and tidal flats that interact with the surrounding oceanic waters via several inlets (Ribeiro et al, 2008). This lagoon is considered a valuable resource for tourism, salt extraction, fisheries and aquaculture, with a long tradition of bivalve harvesting (20% of total area of the lagoon), like the clam Ruditapes decussatus.…”

“…It is possible that differential responses to these contaminant sources are a result of different chemical mixtures, concentrations of high impact pollutants, or effluent treatment practices (Bishop et al 2006b, Ribeiro et al 2008. Industrial effluents represent another mixed contaminant source; they differ from the other contamination sources examined in this study, as they contain comparatively few food subsidies and nutrients while potentially toxic contaminants are often present (such as metals and pesticides) (Costello & Read 1994, Austin 1999, Hylland 2006b.…”

“…It is possible that differential responses to these contaminant sources are a result of different chemical mixtures, concentrations of high impact chemicals, or effluent treatment practices. In several cases, fish abundance was increased by these contamination sources even where a variety of toxic contaminants were present at high concentrations, and in some instances declines in commercially important species were observed following the implementation of improved water quality management (Bishop et al 2006b, Ribeiro et al 2008. In one such study, Ribeiro et al (2008) investigated the impacts of improvements in sewage treatment on fish assemblages living in coastal lagoons in southern Portugal.…”

We conducted a systematic review and meta-analysis of the in situ effects of contaminant sources on fish abundance and species richness. We discuss these effects and examine the role of contaminant sources, habitats, and study systems. We also highlight the role of fish ecology in determining contaminant impacts, mechanisms of impact, and areas for future research. A total of 45 papers were analyzed in the meta-analysis, which revealed that the average change in abundance at contaminated sites was +103× (fish farms), + 40% (sewage studies), -52% (industrial effluent), and -65% (run-off). This analysis suggested that the abundance of fish assemblages in coral reefs was negatively impacted by contaminants and that these reefs are more sensitive than other habitats. Weak trends were observed for species richness, which may suggest that contamination is not having an impact on fish diversity. Some sources of contamination that are also sources of food are having sizeable effects on abundance and richness and are likely to be of commercial and environmental significance. Further research is warranted, particularly where contamination may act as an additional stressor in impacted communities.

“…Ichthyofaunal assemblages in estuaries are very dynamic and can vary spatially, and over a range of temporal scales, e.g. seasons/years/decades (Potter et al, 2016;Ribeiro et al, 2008), seasons (Loneragan and Potter, 1990;Veale et al, 2014) and diel phase (Gray et al, 1998;Young et al, 1997). The production and release of hatchery-reared individuals that do not have cultured broodstock available, i.e.…”

Estimating predation rates of restocked individuals: The influence of timing-of-release on metapenaeid survival

et al. 2018

The success of aquaculture-based enhancement programs is greatly influenced by the survival of released individuals. Immediate post-release mortality through predation is one of the greatest obstacles to the success of releases, and the choice of a release site or time-of-release can be critical in maximising survival. This paper develops a novel quantitative method of estimating predation rate to inform release programs, and describes its use in determining whether hatchery-reared Western School Prawns Metapenaeus dalli should be released into the Swan-Canning Estuary in temperate south-western Australia during the night or day. and Atherinomorus vaigiensis (Atherinidae), were responsible for ~99 % of the predation, and that the total number of postlarval prawns consumed was 288 % higher at night than in the day. These findings suggest that releasing M. dalli during the day will greatly reduce predation and consequently allow a greater survival rate at this release site. The simple methodology developed here could be readily employed to inform release strategies for other species.
