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.

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)

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.

This report describes the results of the first of three expeditions planned to the Kimberley to document the marine flora and fauna of the area. The expedition took place in November 1994 with the assistance of a grant from the National Estates Grant Program.Twenty-two stations were examined. Detailed notes are presented on the station locations and habitat types present. At each station seagrasses, algae, fish, and some invertebrate groups were collected and notes were made on mangroves in the area.Three areas of particular significance were found: the intertidal seagrass beds in the area of Sunday and Tallon Islands, which are the largest known for the Kimberley region; an extensive intertidal system which surrounds Montgomery Island with an area greater than 400 square kilometres; and a hypersaline lagoon on Macleay Island. These areas are described and the reasons for their significance detailed.This report provides an extensive section outlining the coastal geomorphology of the southern Kimberley islands, emphasising the unique intertidal terraces which trap water at low tide and have allowed the development of the seagrass systems at Sunday and Tallon Islands.There have been no published records of the marine algae which occur in the Kimberley. This report provides details of 72 species collected during the expedition. Coralline algae are poorly known and species in this group are currently being worked on taxonomically. Two genera commonly found during the trip are provisionally considered to be undescribed and two species are new records for Western Australia. Eight species of seagrasses were recorded from a total of 15 stations; the number of known localities at which the most common species occurs has been trebled.Two hundred thirty-two species of molluscs, 173 crustaceans, 24 polychaetes,and 197 species of fish were recorded. Potentially new species were found in several groups. Detailed collections were made of additional groups such as echinoderms. The first collections from the Kimberley were obtained of groups such as isopods and nemerteans.The taxonomy of many of the groups collected is poorly known. Material was obtained for specialists in particular groups in Australia and overseas. The material has been sorted and sent to the specialists for examination and determination of species. This work is complex and time consuming, so it has not been possible to provide identifications for this report. However, the material is currently being worked up and will be presented in the scientific literature when it has been completed.

Zooplankton biomass data have been collected in Australian waters since the 1930s, yet most datasets have been unavailable to the research community. We have searched archives, contacted researchers, and scanned the primary and grey literature to collate this dataset (49067 records) of marine zooplankton biomass from waters around Australia, within the geographical extents of 0-60S, 110-160E. Many of these are small-scale datasets , but when combined, they provide over >85 years of large-scale zooplankton community biomass data for Australian waters from 1932 to the present. The data have been standardised, erroneous data removed, and all metadata included. The Australian Zooplankton Biomass Database will be valuable for global change studies, research assessing trophic linkages, and for initialising and assessing biogeochemical and ecosystem models of lower trophic levels. A snapshot of the Australian Zooplankton Biomass Database at the time of this publication has been assigned a DOI and will be maintained in perpetuity by the Australian Ocean Data Network (AODN). The ongoing version of this database will be freely available through the AODN Portal (http://portal.aodn.org.au/) in the near future. This metadata record was based on the following CSIRO metadata record: http://www.marlin.csiro.au/geonetwork/srv/eng/search?uuid=c3c9663f-50ba-41c9-b1ac-b5a9b7e9d4f7.

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.

This report describes the results of the third and final expedition to the Kimberley to document the marine flora and fauna of the area. The expedition took place in November-December 1996 with the assistance of a grant from the National Estates Grant Program. Twenty-four stations were examined. Detailed notes are presented on the station locations and habitat types present. At each station algae, seagrasses, molluscs, fish, crustacea and corals were collected and notes were made on the few mangroves observed in this area. 3.Five areas of particular significance were found. These were: - Station 5, Hedley Island - coral pools, fish, algae and general diversity. - Station 11, Low Water, East Montelivet - extensive coral/coralline reef flat with high diversity coral cover. Large pools, with spectacular coral cover and fish. - Station 13, East side, Cassini Island - geomorphology and coral cover. Station 21, Wild Cat Reefs, eastern reef, west side - high algal diversity. - Station 22, The Breakwater, Montgomery Reef - special reef. This report provides an extensive section outlining the coastal geomorphology of the central Kimberley. There have been no published records of the marine algae which occur in the Kimberley. This report provides details of ca. seventy species collected during the expedition. Coralline algae are poorly known and species in this group are currently being worked on taxonomically. One hundred and forty four species of scleractinian corals, 292 species of molluscs, 89 species of non-caridean decapod crustaceans and 80 species of caridean shrimps, 228 species of fish and 19 barnacles were recorded. Potentially new species were found in several groups. The taxonomy of many of the groups collected is poorly known. Material was obtained for specialists in particular groups in Australia and overseas. The material has been sorted and sent to the specialists for examination and determination of species. This work is complex and time consuming, so it has not been possible to provide identifications for this report. However, the material is currently being worked up and will be presented in the scientific literature when it has been completed.
