New Zealand's Genetic Diversity
1.13 NEW ZEALAND’S GENETIC DIVERSITY NEW ZEALAND’S GENETIC DIVERSITY Dennis P. Gordon National Institute of Water and Atmospheric Research, Private Bag 14901, Kilbirnie, Wellington 6022, New Zealand ABSTRACT: The known genetic diversity represented by the New Zealand biota is reviewed and summarised, largely based on a recently published New Zealand inventory of biodiversity. All kingdoms and eukaryote phyla are covered, updated to refl ect the latest phylogenetic view of Eukaryota. The total known biota comprises a nominal 57 406 species (c. 48 640 described). Subtraction of the 4889 naturalised-alien species gives a biota of 52 517 native species. A minimum (the status of a number of the unnamed species is uncertain) of 27 380 (52%) of these species are endemic (cf. 26% for Fungi, 38% for all marine species, 46% for marine Animalia, 68% for all Animalia, 78% for vascular plants and 91% for terrestrial Animalia). In passing, examples are given both of the roles of the major taxa in providing ecosystem services and of the use of genetic resources in the New Zealand economy. Key words: Animalia, Chromista, freshwater, Fungi, genetic diversity, marine, New Zealand, Prokaryota, Protozoa, terrestrial. INTRODUCTION Article 10b of the CBD calls for signatories to ‘Adopt The original brief for this chapter was to review New Zealand’s measures relating to the use of biological resources [i.e. genetic genetic resources.

Shellfish Diseases and Their Management in Commercial Recirculating Systems
Shellfish Diseases and Their Management in Commercial Recirculating Systems Ralph Elston AquaTechnics & Pacific Shellfish Institute PO Box 687 Carlsborg, WA 98324 Introduction Intensive culture of early life stages of bivalve shellfish culture has been practiced since at least the late 1950’s on an experimental basis. Production scale culture emerged in the 1970’s and today, hathcheries and nurseries produce large numbers of a variety of species of oysters, clams and scallops. The early life stage systems may be entirely or partially recirculating or static. Management of infectious diseases in these systems has been a challenge since their inception and effective health management is a requisite to successful culture. The diseases which affect early life stage shellfish in intensive production systems and the principles and practice of health management are the subject of this presentation. Shellfish Diseases and Management Diseases of bivalve shellfish affecting those reared or harvested from extensive culture primarily consist of parasitic infections and generally comprise the reportable or certifiable diseases. Due to the extensive nature of such culture, intervention options or disease control are limited. In contrast, infectious diseases known from early life stages in intensive culture systems tend to be opportunistic in nature and offer substantial opportunity for management due to the control that can be exerted at key points in the systems. In marine shellfish hatcheries, infectious organisms can enter the system from three sources: brood stock, seawater source and algal food source. Once an organism is established in the system, it may persist without further introduction. Bacterial infections are the most common opportunistic infection in shellfish hatcheries. -
Volume 19 Winter 2002 the Coral Hind, Lapu Lapu, Or Miniata
FREE ISSN 1045-3520 Volume 19 Winter 2002 Introducing a Zonal Based Natural Photo by Robert Fenner Filtration System for Reef Aquariums by Steve Tyree Quite a few natural based filtration systems have been devised by reef aquarists and scientists in the past twenty years. Some systems utilized algae to remove organic and inorganic pollutants from the reef aquarium; others utilized sediment beds. The natural filtration system that I have been researching and designing is drastically different from both of these types. No external algae are used. I believe that all the algae a functional reef requires are already growing in the reef, even if they are not apparent. They include micro-algae, turf algae, coralline algae, single-cell algae within photosynthetic corals, and cyanobacteria with photosynthetic capabilities. Most of the systems that I have set up to research this concept have not included sediment beds. All organic matter and pollutants are recycled and processed within the system by macro-organisms. Sediment beds have not been utilized to process excess Miniata Grouper, Cephalopholis miniata organic debris, but that does not prevent other aquarists from adding them. The main concept behind my system is the use of living sponges, sea squirts, and filter feeders for filtration. Sponges consume bacteria, can reach about twenty inches in length in the wild, and dissolved and colloidal organic material, micro-plankton, The Coral Hind, Lapu about half that in captivity. It is undoubtedly the most and fine particulate matter. Sea squirts consume large Lapu, or Miniata prized member of the genus for the aquarium trade. -

The LD50 for the tissue culture plants of C. willisii was at 25 Gy, which was considered as an appropriate dosage to induced mutations in this plant. About two thousand shoot-tip explants were irradiated at 25 Gy and variants from the M1, M2, M3 and M4 generations were screened for morphological differences. The shoots were th subcultured repeatedly until the 4 generation (M4) to ensure stability of mutants. Although initially many regenerants with different morphological traits were produced, only two mutants remained stable. The mutants obtained were dwarf plants (D1) and plants of taller stature with pigmented leaves (G1) in comparison to control cultures. This was verified from the significant F value from the ANOVA test, where P<0.05. The Inter-Retrotransposon Amplified Polymorphism (IRAP) markers were used to distinguish the D1 and G1 genomes from normal C. -

Smith, Professor, Biomedical Sciences and Pathobiology, Virginia-Maryland Regional College of Veterinary Medicine, Virginia Tech David Pasnik, Research Scientist, Agricultural Research Service, U.S. Department of Agriculture Fish Health and Disease Parasites Striped bass (Morone saxitilis) and hybrid striped bass Parasitic infestations are a common problem in striped (M. saxitilis x M. chrysops) are widely cultured for bass culture and may have harmful health consequences both food and sportfishing markets. Because these fish when fish are heavily parasitized (Smith and Noga 1992). are commonly raised in high densities under intensive aquaculture situations (e.g., cages, ponds, tanks), they Ichthyophthiriosis or “Ich” is caused by the ciliated are often exposed to suboptimal conditions. Healthy protozoan parasite Ichthyophthirius multifiliis in fresh- striped bass can generally resist many of the viral, water or Cryptocaryon irritans in saltwater. These bacterial, fungal, and parasitic pathogens, but the fish parasites cause raised, white lesions visible on the become increasingly susceptible to disease agents when skin and gill (commonly called “white spot disease”) immunocompromised as a result of stress. and can cause high mortalities in a population of fish. The parasite burrows into skin and gill tissue (figure A number of noninfectious problems are commonly 1), resulting in osmotic stress and allowing secondary encountered in striped bass and hybrid striped bass bacterial and fungal infections to become established culture facilities. Factors such as poor water quality, at the site of penetration. The life cycle of the parasite improper nutrition, and gas supersaturation can directly can be completed in a short time, so light infestations cause morbidity (clinical disease) and mortality. -
Vibrio Diseases of Marine Fish Populations
HELGOL~NDER MEERESUNTERSUCHUNGEN Helgolander Meeresunters. 37, 265-287 (1984) Vibrio diseases of marine fish populations R. R. Colwell & D. J. Grimes Department of Microbiology, University of Maryland; College Park, MD 20742 USA ABSTRACT: Several Vibrio spp. cause disease in marine fish populations, both wild and cultured. The most common disease, vibriosis, is caused by V. anguillarum. However, increase in the intensity of mariculture, combined with continuing improvements in bacterial systematics, expands the list of Vibrio spp. that cause fish disease. The bacterial pathogens, species of fish affected, virulence mechanisms, and disease treatment and prevention are included as topics of emphasis in this review, INTRODUCTION It is most appropriate that the introductory paper at this Symposium on Diseases of Marine Organisms should be about vibrios. The disease syndrome termed vibriosis was one of the first diseases of marine fish to be described (Sindermann, 1970; Home, 1982). Called "red sore", "red pest", "red spot" and "red disease" because of characteristic hemorrhagic skin lesions, this disease was recognized and described as early as 1718 in Italy, with numerous epizootics being documented throughout the 19th century (Crosa et al., 1977; Sindermann, 1970). Today, while "red sore" is, without doubt, the best understood of the marine bacterial fish diseases, new diseases have been added to the list of those caused by Vibrio spp. The more recently published work describing Vibrio disease, primarily that appear- ing in the literature since 1977, will be the focus of this paper. Bacterial pathogens, the species of fish affected, virulence mechanisms, and disease treatment and prevention are included as topics of emphasis. -
