Influence of Spring River Flow on the Recruitment of Japanese Seaperch Lateolabrax Japonicus Into the Chikugo Estuary, Japan
RECENT ADVANCES IN THE STUDY OF SCIENTIA MARINA 70S2 FISH EGGS AND LARVAE October 2006, 159-164, Barcelona (Spain) M.P. Olivar and J.J. Govoni (eds.) ISSN: 0214-8358 Influence of spring river flow on the recruitment of Japanese seaperch Lateolabrax japonicus into the Chikugo estuary, Japan JUN SHOJI 1 and MASARU TANAKA 2 1 Takehara Fisheries Research Station, Hiroshima University, Minato-machi 5-8-1, Takehara, Hiroshima 725-0024, Japan. E-mail: [email protected] 2 Laboratory of Estuarine Ecology, Centre for Education and Research of Field Science, Kyoto University, Sakyo, Kyoto 606-8502, Japan. SUMMARY: The estuarine turbidity maximum (ETM) zone is considered to serve as a predation refuge for fish during the early life stages due to the high turbidity and high prey concentration. River flow can be one of the important determinants for survival of early life stages of estuarine dependent fish because it affects both the physical and biological properties of the ETM. We tested the hypothesis that fluctuation of river flow explains the variability in recruitment of Japanese seaperch Lateolabrax japonicus around the ETM region of the Chikugo River estuary, upper Ariake Bay, Japan. Japanese seaperch recruitment showed a 43.3-fold fluctuation from 1990 to 2000 and was inversely correlated with the mean daily river flow of the Chikugo River in March. The recruitment was high and variable in years of low March river flow and was poor in years of high March river flow. We conclude that high river flow potentially decreases Japanese seaperch recruitment in the Chikugo River estuary by blocking the larval migration into the river and by increasing the probability of larval dispersion to the downriver/upper bay areas, where potential predators (jellyfish and Sagitta spp.) were more abundant, and prey (Sinocalanus sinensis) availability and turbidity were lower. -

Bill Workman, [email protected], and Ian Jordan, [email protected] An artist’s concept of a gas giant planet orbiting the cool, red dwarf star Gliese 876. Bill and Ian, you are working on the Hubble long-range (constraint) window with available telescope orbit resources. Since we don’t observing plan (LRP). Please explain the role of the LRP actually schedule the telescope, the task is—by definition—statistical in Hubble operations and the work that creating it entails. in nature. Like any good science project, the ‘fun’ part is dealing with the ILL: Well, it’s not clear we can describe what we do in less than ‘Hubble uncertainties in the system. In this case, this means predicting HST behavior BTime’, but we’ll try! and what the whole General Observer (GO) observing program will look like BILL & IAN: Primarily the Long Range Planning Group (LRPG) and the LRP for the cycle. exist to help the Institute and user community maximize the science output of the Hubble Space Telescope (HST). Observers see the LRP as a set of plan How do you know when you are done with the LRP? windows that represent times when a particular set of exposures are likely IAN: Well, the long range plan is never done! Perhaps the LRP logo should to be observed by the telescope, similar to scheduling observing runs at a be a yin-yang symbol? ground-based observatory. -

Newman Department of Fisheries 3rd floor SGIO Atrium 168-170 St George’s Terrace PERTH WA 6000 Telephone (08) 9482 7333 Facsimile (08) 9482 7389 Website: www.fish.wa.gov.au ABN: 55 689 794 771 Published by Department of Fisheries, Perth, Western Australia. Fisheries Occasional Publications No. 80, September 2010. ISSN: 1447 - 2058 ISBN: 1 921258 90 X Information about this guide he intention of the North Coast Fish Identification Guide is to provide a simple, Teasy to use manual to assist commercial, recreational, charter and customary fishers to identify the most commonly caught marine finfish species in the North Coast Bioregion. This guide is not intended to be a comprehensive taxonomic fish ID guide for all species. It is anticipated that this guide will assist fishers in providing a more comprehensive species level description of their catch and hence assist scientists and managers in understanding any variation in the species composition of catches over both spatial and temporal scales. Fish taxonomy is a dynamic and evolving field. Advances in molecular analytical techniques are resolving many of the relationships and inter-relationships among species, genera and families of fishes. In this guide, we have used and adopted the latest taxonomic nomenclature. Any changes to fish taxonomy will be updated and revised in subsequent editions. The North Coast Bioregion extends from the Ashburton River near Onslow to the Northern Territory border. Within this region there is a diverse range of habitats from mangrove creeks, rivers, offshore islands, coral reef systems to continental shelf and slope waters. -
