A Checklist of Fishes from Cuvier Island, North-Eastern New Zealand, By TANE 27, 1981 A CHECKLIST OF FISHES FROM CUVIER ISLAND, NORTH-EASTERN NEW ZEALAND G.D. Housley, D.J. Riddell, and R.V. Grace* Department of Zoology, University of Auckland, Private Bag, Auckland *274a Birkdale Road, Birkenhead, Auckland 10 SUMMARY Over a period of five days of scuba diving, 51 species of fish belonging to 28 families were identified around Cuvier Island. INTRODUCTION Cuvier Island is situated approximately 40 km east of the Coromandel Peninsula, north-eastern New Zealand. Influenced by the East Auckland Current, we would expect the fish fauna to be similar to that described from other islands off north-eastern New Zealand. The underwater topography in the study area varied from moderately sheltered shallow coves with low relief, to steep drop-offs with complex topography and depths exceeding 45 metres, thus providing a wide range of habitats. METHODS Nine areas were surveyed around the island, in areas sheltered from the westerly winds that prevailed over the five days from 21 to 25 May 1980 (Fig. 1). Four divers performed a total of 20 scuba dives of varying duration and depth, to a maximum of 45 metres. The fish species seen on all dives were combined from all areas for this checklist. Habitat notes were also made for each dive site. RESULTS 51 species of fish from 28 families were identified and are listed below. Nomenclature generally follows that of Thompson (1981). In addition to the fish listed, a hybrid labrid (Ayling 1980) was noted which has not been further identified.

SITE NOTES Three areas are discussed to relate general habitat to the fish fauna. Observations of special interest are also noted. LANDING BAY. Dives 1,2,8 & 9 Landing Bay is a mobile boulder beach which rises steeply above low water level but has a relatively gently sloping subtidal topography. The broken reef and boulder floor with kelpbeds of moderate density extends outwards for 200 metres. The brown algae Carpophyllum maschalocarpum and C. angustifolium in the shallows are gradually replaced by Ecklonia radiata in deeper water. At 15 metres depth, sand patches occur amongst the rocky areas. In the centre of the bay the topography is flatter with the hard rock substrate supporting little or no Ecklonia radiata, but a high density 39 of the urchin Evechinus chloroticus. Red pigfish (Bodianus oxycephalies) reach their highest density here. Very large schools of demoiselles (Chromis dispilus) and blue maomao (Scorpis violaceus) tend to be more common in the boulder areas with associated kelp closer to shore, where other labrids and red moki (Cheilodactylus spectabilis) are also common. 500 metres out from Landing Bay and to the west (see dive 8, Fig. 1), a surface reef runs out which drops steeply to 33 metres. Slopes around the reef are covered with Ecklonia radiata. Large hydroids and sponges, including the bright yellow Iophon sp., occur in the deeper water, with feather-stars (Comanthus novaezelandiae) being extremely common in places. The rare fanworm Protula bispiralis is found occasionally attached to rock near the sand at 30 metres. In this area two yellow morays (Gymnothorax prasinus) were seen to capture a red crayfish (Jasus edwardsii) under the abdomen and drag it into the crevice they occupied. FAIRCHILD BAY. Dives 5 & 7 Fairchild Bay is a mobile boulder beach similar to Landing Bay but partly sheltered by a large rock known as Scott's Monument. Juvenile black angelfish {Parma alboscapularis) were common in the shelter of boulder heaps in 2 metres of water. In this area juvenile trevally (Caranx georgianus) approximately 50 mm in length were seen to act as cleaners. When approached by an adult black angelfish, the trevally removed parasites from its flank. TOWER HILL POINT. Dives 4 & 6 At this site the rocky bottom dropped steeply into deep water (45 metres). Macroalgae typical of heavy wave-exposure (Carpophylium angustifolium and Lessonia variegata) were present in shallow water, with Ecklonia radiata appearing in deeper water. Near the surface, school fish such as koheru (Decapterus koheru) and kahawai (Arripis trutta) were common, replaced by abundant butterfly perch (Caesioperca lepidoptera) in deep water. DISCUSSION By reducing the number of species to a comparative list by the method outlined by Willan et al (1979), the list represents 49 species from 26 families for Cuvier Island. The number is very high considering the small number of dives undertaken and the somewhat compressed study boundaries due to bad weather. If comparison is made with the cumulative species sighting versus dive number curve of Nicholson (1979) for the Cavalli Islands, the 49 species recorded for Cuvier Island in twenty dives compares well with the 42 species in the first twenty dives at the Cavalli Islands. This could reflect an overall fish diversity greater at Cuvier Island than that of the Cavalli Islands 40 Group. Such a comparison, however, is valid only if diving effort was spread evenly through successive dives across all habitats represented. Direct comparison of the Cuvier list with standardised data from various sources throughout northern New Zealand, presented by Nicholson (1979), suggests that Cuvier Island (49 species from 26 families) ranks along with White Island (also 49 species from 26 families). Without "rate of discovery" information, however, comparison between areas is difficult because of the relationship between search time, habitats investigated, and the number of species seen - a difficulty pointed out by Nicholson (1979). It is clear, however, that the presence of certain species at Cuvier Island suggests a fairly strong influence from the oceanic subtropical East Auckland Current, as at many of the offshore islands of north• eastern New Zealand. Of particular note in this respect are Gymnothorax ramosus (mosaic moray), Chromis hypsilepis (single- spot demoiselle), Pseudolabrus inscriptis (green wrasse), P. luculentus (orange wrasse), Suezichthys sp. (crimson cleanerfish), and Forsterygion sp. 5 (blue-dot blenny). ACKNOWLEDGEMENTS The authors wish to thank Dr J.H. Choat for his helpful criticism of this paper, and Glenn White for his participation in the diving. REFERENCES Ayling, A.M. 1980: Hybridisation in the genus Pseudolabrus (Labridae).

  • A COMPARATIVE ACCOUNT of the SMALL PELAGIC FISHERIES in the APFIC REGION by M
    A COMPARATIVE ACCOUNT OF THE SMALL PELAGIC FISHERIES IN THE APFIC REGION by M. Devaraj and E. Vivekanandan Central Marine Fisheries Research Institute Cocbin-682014, India Abstract The production of the small pe/agics in the APFIC region was 1.2 mt/sq. km during 1995. Among the four areas in the region, the small pe/agics have registered (i) the maximum annual fluctuations in the western Indian Ocean; (ii) the highest increase duri'}i the past two decades along the west coast of Thailand in the eastern Indian Ocean; and (iii) the consistent decline in the landings during the past one decade along the Japanese coast in the northwest Pacific Ocean. The short rnackerels emerged as the largest fishery in the APFlC region, fom'ing 19.5% of the landings of the small pelagics in 1995. The group consisting afthe sardines and the anchovies has shown clear signs of decline during the past one decade in almost the entire region. Most of the small pelagics have unique biological characteristics such as fast growth, short longevity, late maturity, high nalllral mortality, shoaling behaviour, high fecundity and severe recruitment fluctuations. As many species of the small pelagics undertake migration, collaborative research programmes and close coordination are required among the APFle countries for the stock assessment of all the major species. The management measures under implementation in these countries have been reviewed, with suggestions for regional cooperation for the management of the stocks of the small pelagics. INTRODUCTION The Asia-Pacific Fishery Commission covers four oceanic areas, which have been classified by the FAO as the western Indian Ocean (FAO Statistical Area 51), eastern Indian Ocean (Area 57) , northwest Pacific Ocean (Area 61) and western central Pacific Ocean (Area 71).

  • Approaching the Prehistory of Norfolk Island
    © Copyright Australian Museum, 2001 Records of the Australian Museum, Supplement 27 (2001): 1–9. ISBN 0 7347 2305 9 Approaching the Prehistory of Norfolk Island ATHOLL ANDERSON1 AND PETER WHITE2 1 Department of Archaeology & Natural History, Research School of Pacific and Asian Studies, Australian National University, Canberra ACT 0200, Australia [email protected] 2 Archaeology, University of Sydney, Sydney NSW 2006, Australia [email protected] ABSTRACT. Norfolk Island, on the northeast edge of the Tasman Sea, is of volcanic origin and moderate height. A humid, forested subtropical landmass, it had a diverse range of natural resources, including some food plants such as Cyathea, forest birds such as pigeon and parrot species and substantial colonies of seabirds, notably boobies and procellariids. Its shoreline had few shellfish, but the coastal waters were rich in fish, of which Lethrinids were especially abundant. The island had no inhabitants when discovered by Europeans in A.D. 1774. It was settled by them in A.D. 1788. From the eighteenth century discovery of feral bananas and then of stone adzes, knowledge of the prehistory of Norfolk Island has developed over a very long period. Collections of stone tools seemed predominantly East Polynesian in orientation, but Melanesian sources could not be ruled out. Research on fossil bone deposits established the antiquity of the human commensal Rattus exulans as about 800 B.P. but no prehistoric settlement site was known until one was discovered in 1995 at Emily Bay during the Norfolk Island Prehistory Project.

EDITOR: Mrs Ajetomobi School of Agricultural Sciences Lagos State Polytechnic Ikorodu, Lagos 2 BIO 313 COURSE GUIDE Introduction Animal Ecology (313) is a first semester course. It is a two credit unit elective course which all students offering Bachelor of Science (BSc) in Biology can take. Animal ecology is an important area of study for scientists. It is the study of animals and how they related to each other as well as their environment. It can also be defined as the scientific study of interactions that determine the distribution and abundance of organisms. Since this is a course in animal ecology, we will focus on animals, which we will define fairly generally as organisms that can move around during some stages of their life and that must feed on other organisms or their products. There are various forms of animal ecology. This includes: • Behavioral ecology, the study of the behavior of the animals with relation to their environment and others • Population ecology, the study of the effects on the population of these animals • Marine ecology is the scientific study of marine-life habitat, populations, and interactions among organisms and the surrounding environment including their abiotic (non-living physical and chemical factors that affect the ability of organisms to survive and reproduce) and biotic factors (living things or the materials that directly or indirectly affect an organism in its environment).
