Study of the genetic structure, demography and recruitment of several species of marine invertebrates.

Fish larvae were sampled along a five-station transect extending from inshore (18m depth) to offshore waters (1000m depth) of the coast of South-Western Australia (see thumbnail). 148 taxa from 93 teleost families were identified. The temporal and spatial structure of the fish assemblages were analysed in relation to the environmental variables. Assemblages were closely correlated to water masses (Capes and Leeuwin Current)

Many studies compare utilization of different marine habitats by fish and decapod crustaceans; few compare multiple vegetated habitats, especially using the same sampling equipment. Fish and invertebrates in seagrass, mangrove, saltmarsh, and nonvegetated habitats were sampled during May–August (Austral winter) and December–January (Austral summer) in the Barker Inlet-Port River estuary, South Australia. Sampling was undertaken using pop nets in all habitats and seine nets in seagrass and nonvegetated areas. A total of 7,895 fish and invertebrates spanning 3 classes, 9 orders, and at least 23 families were collected. Only one fish species, Atherinosoma microstoma, was collected in all 4 habitats, 11 species were found in 3 habitats (mangroves, seagrass, and nonvegetated), and 13 species were only caught in seagrass and nonvegetated habitats. Seagrass generally supported the highest numbers of fish and invertebrates and had the greatest species richness. Saltmarsh was at the other extreme with 29 individuals caught from two species. Mangroves and nonvegetated habitats generally had more fish, invertebrates, and species than saltmarsh, but less than seagrass. Analyses of abundances of individual species generally showed an interaction between habitat and month indicating that the same patterns were not found through time in all habitats. All habitats supported distinct assemblages although seagrass and nonvegetated assemblages were similar in some months. The generality of these patterns requires further investigation at other estuaries. Loss of vegetated habitats, particularly seagrass, could result in loss of species richness and abundance, especially for organisms that were not found in other habitats. Although low abundances were found in saltmarsh and mangroves, species may use these habitats for varying reasons, such as spawning, and such use should not be ignored.

In February and June 1983, fishes and benthic fauna were sampled to provide quantitative estimates of densities and volumes of the benthic invertebrate animals and biomass of the seagrass in summer, as well as abundances of the fishes occurring during the day and night and in both summer and winter in Amphibolis seagrass beds and sand flats at Monkey Mia Shark Bay, Western Australia.

Study on the major marine habitats of the proposed Dampier Archipelago/Cape Preston marine conservation reserve.

Larval fishes are a useful metric of marine ecosystem state and change, as well as species-specific patterns in phenology. This information sheds light on larval distribution and spawning for fisheries management needs. This dataset includes larval fish abundances collected from 12 voyages around Australia since 1983, as well as more recent data from the Marine National Facility (MNF). The backbone of the dataset is from five Integrated Marine Observing Systems (IMOS) National Reference Stations (NRS) (North Stradbroke, Port Hacking, Maria Island, Kangaroo Island and Rottnest Island), between 2014 and 2021 as part of the IMOS Larval Fish Monitoring Sub-Facility of the National Mooring Network Facility (data currently available up to 2021). This adds information to the biological, ecological and oceanic measurements already sampled at these long-term monitoring sites. For information on using the data from the NRS stations and research voyages, please refer to Smith et al., 2018. It is advised that anyone using this data should read this methodology or contact the project contact person to understand the nuances of each sampling and analysis chain. The fish larvae product is available as raw count product, where fish larvae are classified to the lowest taxonomic level possible (with 228 taxonomic groups identified so far, at either the Family, Genus, or Species level). Associated metadata includes location, temperature, salinity, net type, and tow volume. There is a static snapshot of the database as at March 2018 (https://dx.doi.org/10.4225/69/5ab33c62f9c52), and this has been documented in a Scientific Data publication (Smith et al., 2018). This metadata record provides access to the dynamic (most recent) version of the database, which can serve as a data repository for survey of larval fish assemblages in the region.

Measures of abalone biology - length, weight, growth rate in the Spencer Gulf, South Australia.

FishBase (31 000 Species, 270 600 Common names, 46 900 Pictures, 42 400 References, 1620 Collaborators, 33 million Hits/month). FishBase is an information system with key data on the biology of all fishes. Similar to an encyclopedia, FishBase contains different things for different people. For example, fisheries managers will dive into the largest existing compilation of population dynamics data; teachers and students will find numerous graphs illustrating basic concepts of fish biology; taxonomists will enjoy access to the November 2000 update of Eschmeyers (1998) Catalog of Fishes databases; conservationists will use the lists of threatened fishes for any given country (Hilton-Taylor 2000); policymakers may be interested in a chronological, annotated list of introductions to their country; research scientists, as well as funding agencies, will find it useful to gain a quick overview of what is known about a certain species; zoologists and physiologists will have the largest existing compilations of fish morphology, metabolism, gill area, brain size, eye pigment, or swimming speed at their fingertips; ecologists will likewise use data on diet composition, trophic levels, food consumption and predators as inputs for their models; geneticists will find the largest compilation of allele frequencies; the fishing industry will find proximate analyses, as well as processing recommendations for many marine species; anglers will enjoy a listing of all game fishes occurring in a particular country (IGFA 1994); and scholars interested in local knowledge will find more than 100,000 common names of fishes together with the language/culture in which they are used and comments on their etymology.
