(2014). Habitats and areas of particular significance for coastal finfish fisheries management in New Zealand: A review of concepts and life history knowledge, and suggestions for future research. New Zealand Aquatic Environment and Biodiversity Report No. 125. 202 p. Most fished coastal marine teleost finfish have life histories that can be divided up into spawning/reproduction, eggs and larval periods, a juvenile phase, and an adult phase, when reproductive maturity is reached. Elasmobranches vary slightly from this, with some species being live-bearers, while others produce egg capsules that are laid on the seafloor, which eventually hatch as fully formed juveniles. Hurst et al. (2000a) undertook a review of “Areas of importance for spawning, pupping, or egg-laying, and juveniles of New Zealand coastal fish”. This current review follows on from that document, updating our understanding with information generated over the following 12 years, as well as looking at adult migrations and movements in more detail. Thirty eight species which have some component of their life cycle in coastal waters (defined as less than 200 m water depth) are examined, in terms of spawning, oceanographic transport, nursery habitats, adult habitats, adult migrations and movements, and population connectivity and stock

The objective of the monitoring was to describe the reef fish communities and to establish whether populations within the marine reserve were demonstrating any changes in abundance or size that could be attributable to the removal of fishing pressure. The underwater visual census method was used to survey the four lo- cations (marine reserve and three non-reserve locations). It was found that all four locations were characterised by moderate densities of spot- ties, scarlet wrasse and reef-associated planktivores such as blue maomao, sweep and butterfly perch.

FRY University of Toronto THE OSMOREGULATORY METABOLISM OF THE STARRY FLOUNDER, PLATICHTYS STELLATUS ABSTRACT Energy demands for osmotic regulation and the possible osmoregulatory role of the thyroid gland were investigated in the euryhaline starry flounder, Platichthys stellatus. Using a melt• ing-point technique, it was established that flounder could regulate body fluid concentration independent of widely divergent environ• mental salinities. Small flounder experienced more rapid disturb• ances of body fluid concentration than large flounder after abrupt salinity alterations. The standard metabolic rate of flounder adapted to fresh water was consistently and significantly less than that of marine flounder. In supernormal salinities standard metabolic rate was significantly greater than in normal sea water.

  • A Checklist of Fishes of the Aldermen Islands, North-Eastern New Zealand, with Additions to the Fishes of Red Mercury Island
    13 A CHECKLIST OF FISHES OF THE ALDERMEN ISLANDS, NORTH-EASTERN NEW ZEALAND, WITH ADDITIONS TO THE FISHES OF RED MERCURY ISLAND by Roger V. Grace* SUMMARY Sixty-five species of marine fishes are listed for the Aldermen Islands, and additions made to an earlier list for Red Mercury Island (Grace, 1972), 35 km to the north. Warm water affinities of the faunas are briefly discussed. INTRODUCTION During recent years, and particularly the last four years, over 30 species of fishes have been added to the New Zealand fish fauna through observation by divers, mainly at the Poor Knights Islands (Russell, 1971; Stephenson, 1970, 1971; Doak, 1972; Whitley, 1968). A high proportion of the fishes of northern New Zealand have strong sub-tropical affinities (Moreland, 1958), and there is considerable evidence (Doak, 1972) to suggest that many of the recently discovered species are new arrivals from tropical and subtropical areas. These fishes probably arrive as eggs or larvae, carried by favourable ocean currents, and find suitable habitats for their development at the Poor Knights Islands, where the warm currents that transported the young fish or eggs maintain a water temperature higher than that on the adjacent coast, or islands to the south. Unless these fishes are able to establish breeding populations in New Zealand waters, they are likely to be merely transient. If they become established, they may begin to spread and colonise other off-shore islands and the coast. In order to monitor any spreading of new arrivals, or die-off due to inability to breed, it is desirable to compile a series of fish lists, as complete as possible, for the off-shore islands of the north-east coast of New Zealand.

  • Catch and Effort Data
    Chapter 11: The Inland Waters River Fishery Information System CHAPTER 11: INLAND WATERS RIVER FISHERY INFORMATION SYSTEM 11.1 Background The Inland Waters River fishery is a multi-species, multi-gear fishery encompassing the South Australian sector of the River Murray and its backwaters (Map 11.1). Historically, the fishery was based on harvesting Murray cod (Maccullochella peelii peelii), golden perch (Macquaria ambigua), and bony bream (Nematalosa erebi). The fishery was restructured in July 2003 to a non-native dominate fishery and the commercial fishing for significant native species is now prohibited. The fishery is now based predominantly on the taking European carp (Cyprinus carpio) and redfin perch (Perca fluviatilis). There are a total of 6 licence holders who operate within the fishery. Prior to the restructure 30 license holders fished the river, each with a designated reach. Up to December 2007 SARDI production tables hold in excess of 270,000 daily records. Data is held from 1984/85 to current and is continually being updated. Refer to Figure 11.3 for an entity relationship diagram of the inland waters system that encompasses the River Fishery.
