Previous research has shown that a range of physical and biological drivers can influence the composition of faunal assemblages occupying localities within streams. There is much debate in the literature about which of these is more important.

Abstract:

Estuaries are widely recognized as important habitats for the early life history stages of commercially and recreationally important marine fish species. In general the estuaries of northeast Florida are understudied, and there is a need to characterize the ichthyoplankton community at this important faunal boundary between temperate and tropical marine zones. To determine community structure and temporal patterns in the distribution and abundance of larval fish ingressing in to the Guana-Tolomato-Matanzas (GTM) estuary through its two inlets (St. Augustine and Matanzas), ichthyoplankton were

Abstract:

Aspects of the biology of common fish species in the Avon-Heathcote Estuary were investigated from two distinct types of sample site, during two sample periods between July 1996 and April 1997. The sites consisted of sites 1-6 (channel sites), which were sampled using a seine net, and estuarine fringe sites A-F, which were dip-net sampled. Although a relatively low diversity of fish species were captured, this was believed to be partly due to sampling methods and conditions. The species that were captured however did appear to be healthy, and were feeding in the estuary. Gonad analyses indicat

Chapters one and two of this work contain a study of helically-coiled spiral coprolites. Spiral coprolites with complex microstructures have been interpreted as enterospirae – fossilized valvular intestines (Fritsch 1907, Williams 1972). However other evidence seems to indicate that recent dogfish produce spiral faecal pellets with complex microstructures (McAllister 1985). The search for an answer to the problem of whether certain spiral coprolites are fossilized intestines or faecal pellets includes a study of diet and the physiology of digestion in fishes, with particular attention to those

Abstract:

Artificial reefs have been deployed throughout the world for a range of different purposes and thus differ in their characteristics. To better understand how their designs and implementation differ spatially, temporally and according to their stated purpose, an extensive collation of information on artificial reefs is needed. Furthermore, in Australia and particularly Western Australia, artificial reefs are increasingly being deployed to enhance recreational fishing experiences and catch rates of key species. To address these topics, this thesis aimed to conduct a systematic literature review

Estuaries are amongst the most productive ecosystems and act as important nurseries and habitats for aquatic fauna. Microtidal estuaries (tidal range <2 m) are particularly prone to climate change, the effects of which on fish communities and future predictions on their state under climate change are not well understood, especially for small estuaries (<1 km2). This study quantitatively determined the fish fauna in the nearshore and offshore waters of eight microtidal estuaries (including six <1 km2) with varying extents of connectivity to the ocean in the Albany region of south-western Austra

The arrival of a non-native species to has the potential to shape native communities by influencing ecological interactions such as predation, foraging, competition and disease transfer. A designation of invasive is applied to an introduced non-native species that has the potential to threaten the continued wellbeing of a native species, pose a risk to human health or negatively impact the economy. The European bullhead (Cottus perifretum) is a freshwater benthic-dwelling fish that is native to England but considered invasive in Scotland. The species was first reported in Scotland in the 1950'

Abstract:

The number of artificial reef deployments around Australia has increased in recent years due to their popularity amongst recreational fishers. As these reefs modify the environment and its associated fauna, monitoring is required to ensure that any negative impacts to the surrounding area are assessed and minimised. Given this and the high cost of purpose-built artificial reefs, there is a need to develop cost-effective monitoring methods to determine their faunal composition. To address this need, this thesis reviewed methods for monitoring the faunas of artificial reefs and utilised the Bait

Parasitic diseases account for a large portion of this losses. In Brazil there are records of various parasites causing damage, and in Goiás were not found recent data on the occurrence of parasitic infections in commercial fish farms. This study aimed to identify and establish the occurrence of ectoparasites of tambac

A conectividade é um fator chave na manutenção de metacomunidades. A conectividade hidrológica vem sendo estudada ao longo dos anos, porém poucos trabalhos de fato discriminam, apropriadamente, os conceitos de conectividade estrutural e funcional. O sistema Tramandaí possui formação geológica recente, situa-se na região do litoral norte do estado do Rio Grande do Sul e possui 41 lagoas conectadas por canais que foram categorizados previamente através de valores de atrito baseados no custo de dispersão dos peixes. Porém, essas conexões não foram exploradas empiricamente, com isso nosso objetivo

Abstract:

The purpose of the report was to analyze the status of fish and shellfish stocks and the effects of consumerism and fishing, (the emphasis being on the North sea and Swedish west coast). The UN's Food and Agriculture Organization estimated that 85 % of global fish stocks are being overexploited and in the EU it's 72 % of the stocks. Worldwide fish stocks have decreased 70-90 % since the 1950´s. The global landings are 80 million tonnes every year and of that 53 million tonnes gets produced for human consumption, while the remaining 27 million are produced for animal feed. The fishing politics

Pyrethroids appear as the option due to low toxicity displayed to birds and mammals, and the low bioaccumulation along the trophic chain. The pyrethroid insecticide λ-cyhalothrin (LCH) is used against a variety of arthropods. These chemicals

Abstract:

La Corse, avec ses 3 000 km de linéaire de cours d’eau, possède un réseau hydrographique particulièrement dense et complexe. A cette complexité vient s’ajouter celle des peuplements piscicoles actuels, fruits de vagues successives d’introductions d’espèces dans les cours d’eau et les plans d’eau de l’île. Si la Corse est caractérisée par une faune piscicole native faiblement diversifiée (seulement quatre espèces), plus d’une vingtaine d’espèces introduites sont venues augmenter artificiellement cette diversité depuis la fin du 19ème siècle.
