Presentation by Laurie Austen Toheroa PRESENTATION BY LAURIE AUSTEN “Imagination will often carry us to worlds that never were. But without it we go nowhere”. Carl Sagan Not your usual conservationist Not your usual conservationist INTRODUCTION TOHEROA – Paphies Ventricosa Māori History, which I am not an expert, I advise you seek expertise from local Kaumātua and Kuia. Recent History: I have sourced this through multiple written and verbal accounts; research and data I have read, complemented by information I have gathered personally. DEPLETION Theories: -Commercial harvesting -Forestry and Pingao -Locals ate ‘em -Birds -Vehicles and Buses -The Father In law Canning Factory and Recreational Harvest Forestry and Pingao The Locals Ate ‘Em/Birds Poachers are blamed Birds Vehicles and Buses Vehicles Buses Commercial Vehicles The Father In law Sam Sharp spent a majority of his life on the ocean as a seaman and a fisherman. His theory was that weather patterns had changed over his lifetime. “It is likely that the early onset of easterlies winds in 1938 caused the death of some 20 million Toheroa on 90 mile beach, and probably the whole west coast was affected. These mass mortalities have been quite common, the last occurring in 1971”. New Zealand Geographic – Number 9 January – March 1991 Article written by Glenys Stace Whether it is Weather?

We can not get the sand dune build from this type of weather pattern. Speculation “As you probably know New Zealand is currently receiving a sever blast of cold energy sweeping up from the Antarctic Region with temperatures at record lows. This is pure speculation on my part but after reading reports of your study I wonder if this should not have been expected at some time. With the concentration of polar winds and cold energy in the Antarctic region being constrained by warming of upper latitudes is it not logical that as Winter peaks and the warm retreats, this restrained focused cold energy would at some time be released. This would be very similar to Super Storms releasing and dissipating the heat energy built up in the Pacific Ocean during an El Nino Event. I suppose that if sufficient energy is released from the Antarctic it is possible that for a time the concentration effect will abate reducing winds allowing warming of the region and ice melt to resume”.

The modification of toheroa habitat by streams on Ripiro Beach A thesis submitted in partial fulfilment of the requirements for the degree of Master of Science (Research) in Environmental Science at The University of Waikato by JANE COPE 2018 ―We leave something of ourselves behind when we leave a place, we stay there, even though we go away. And there are things in us that we can find again only by going back there‖ – Pascal Mercier, Night train to London i Abstract Habitat modification and loss are key factors driving the global extinction and displacement of species. The scale and consequences of habitat loss are relatively well understood in terrestrial environments, but in marine ecosystems, and particularly soft sediment ecosystems, this is not the case. The characteristics which determine the suitability of soft sediment habitats are often subtle, due to the apparent homogeneity of sandy environments.

  • Contaminants in Shellfish Flesh an Investigation Into Microbiological and Trace Metal Contaminants in Shellfish from Selected Locations in the Wellington Region
    Contaminants in shellfish flesh An investigation into microbiological and trace metal contaminants in shellfish from selected locations in the Wellington region Prepared by: J R Milne Environmental Monitoring and Investigations Greater Wellington Regional Council Executive summary The Wellington region’s varied and extensive coastline is utilised for both traditional and recreational harvesting of a number of shellfish species. Greater Wellington Regional Council periodically monitors the safety of these shellfish for human consumption. This report presents the results of the 2006 investigation, focusing on microbiological and trace metal contaminants in tuatua, cockles and blue mussels from selected sites in the western Wellington region. Faecal coliform indicator bacteria were detected in eight out of a total of 58 shellfish samples. Four of the eight results above detection were recorded in cockle samples collected from Porirua Harbour. No samples had bacteria present at a concentration that exceeded the recommended microbiological guidelines for edible tissue. Cadmium, chromium, copper, lead, mercury, nickel and zinc were all present in the three species of shellfish examined. However, none of the metal concentrations exceeded the national food standards for edible tissue, where standards exist. The tuatua and cockle sample results showed little spatial variation in mean metal concentrations, with similar concentrations recorded between most sampling sites. However, there was some spatial variation in metal concentrations in the mussel samples from Wellington Harbour. Samples collected adjacent to Frank Kitts Park and the Thorndon Container Wharf in the inner harbour generally recorded the highest concentrations, while samples collected from Mahanga Bay, Shark Bay and Sunshine Bay consistently recorded the lowest concentrations.

  • Living Blue: Marine Reserves Marine Foodweb Game
    Living Blue: Marine Reserves Marine Foodweb Game I play this game after the marine reserves talk, which introduces the concept of food webs and the need to conserve whole ecosystems, not just individual species. The page with all the animals on it can also be printed off for the children to do in class as a follow-up activity. Minimum of 8 players Use cards in ordered numbers to make sure the game will work Laminated cards have been made up, with a string to put around the child’s neck. Take along a bunch of precut strings. Some kids will need more than one piece. The game is crazy at first, all kids running around and changing their minds and general chaos. This is how it should be! Give them a few minutes to get themselves into a knot, then stop them all and help them to do it methodically, starting with the sun and the others joining up one by one. Then once they are all joined up, choose one child to become “extinct” by sitting down. All the others that feel their string being pulled need to sit down too. The effect will ricochet until most of the kids are sitting down. This explains why each animal is an important part of the foodweb. 1.The sun 16.Moray eel 2.Seaweed 17.Manta ray 3.Phytoplankton 18.Barnacle 4.Mussels 19.Hawkfish 5.Paua 20.Tern 6.Kina 21.Shark 7.Snapper 22.Squid (eat mullet, eaten by albatross) 8.Starfish 23.Yellow-eyed mullet (eat zooplankton, eaten by squid) 9.Zooplankton 24.Albatross (eats squid) 10.Blenny 25.Blue penguin (eats fish, eaten by shark) 11.Mullet 26.Seahorse (eats zooplankton, no predators) 12.Seal 27.Limpets (eat seaweed, eaten by starfish and octopus) 13.Fin whale 28.Dolphin (eats squid, fish) 14.Orca 29.Crayfish 15.Octopus 30.Tuna (eats small fish, eaten by sharks) Marine food web.

  • Aquaculture Brochure Email.Indd
    AQUACULTURE IN NEW ZEALAND A DIVISION OF NEW ZEALAND TRADE AND ENTERPRISE New Zealand is one of the world’s fi nest locations for aquaculture. The New Zealand government, through Investment New Zealand, is committed to helping investors discover the opportunities that New Zealand offers aquaculturists and assisting inward investment to this growing sector. INTRODUCTION New Zealand has thousands of kilometres of pristine, unpolluted coastline situated in the vast South Pacifi c Ocean. Its isolated position, far removed from intensive human activity, and many sheltered harbours and bays, make New Zealand the perfect location for growing a diverse array of shellfi sh, fi nfi sh, seaweed and other aquatic and marine organisms. 01 New Zealand’s aquaculture sector has advanced at a rapid rate since the late 1980s, having grown at an average annual rate of 11.7% by volume over the 20 years to 2005, yet it remains in the early stages of its development. The industry is based on natural competitive advantages, supported by in-depth knowledge, excellent research capability and a spirit of innovation. Global demand for aquaculture products is rapidly rising. With wild fi sheries production static due to declining stocks, there is a continuing shift toward sustainable fi sheries practices including aquaculture. The aquaculture industry is of increasing social and economic importance in New Zealand. New Zealand has developed a structured system of aquaculture legislation to manage the competing demands for coastal marine space and to evaluate the impact of aquaculture on the values placed on the land and coast. There are many successful ventures in the New Zealand aquaculture industry.

  • 1 Country Note on National Fisheries Management
    COUNTRY NOTE ON NATIONAL FISHERIES MANAGEMENT SYSTEMS -- NEW ZEALAND Summary 1. This paper provides an overview of New Zealand’s management of commercial fisheries. It is New Zealand’s country note contribution to the OECD Fisheries Committee’s review of the use of management instruments/incentives in OECD countries. This review forms part of the Committee’s further examination of economic aspects relating to the transition to sustainable fisheries. 2. Part I of this paper briefly describes New Zealand’s commercial fisheries1. Part II describes the regime used to manage fisheries and information is provided on objectives, management instruments and institutional arrangements. This part outlines the Quota Management System (QMS), which is New Zealand’s preferred way of managing commercial fisheries and is used to manage most stocks in New Zealand fisheries waters. 3. Part III assesses the attributes of the property rights that are a component of the QMS. Quota shares are allocated to fishers when a stock becomes subject to the QMS. Each quota share is an ownership right in perpetuity and each year it generates an Annual Catching Entitlement (ACE). Quota shares are considered to demonstrate certain attributes of property rights – exclusivity, duration, quality of title, transferability, divisibility and flexibility. Opportunities exist for improving flexibility in use of the catching entitlements generated by quota shares. New Zealand is implementing an approach that enables quota share owners to act collectively and to propose legally recognised fisheries plans. This approach means quota share owners will be able to shape the management of the fishery, which should lead to more efficient use of resources and increases in fishery and quota share value.

INTRODUCTION Quantitative stock assessments are available for PAU 4, 5A, 5B, 5D and 7 and these are given separately. 1.1 Commercial fisheries Paua inhabit shallow waters (generally less than 6 m) off the coastline of New Zealand. The commercial fishery for paua dates from the mid-1940s, when shell was marketed and the meat generally discarded. Both meat and shell were sold from the late 1950s. Since the 198687 fishing season, the fishery has been managed with an individual transferable quota system and a total allowable commercial catch (TACC) for each of eight Quota Management Areas. Total reported landings of paua and TACCs are shown in Table 1, while Figure 1 shows the historical landings and TACC for the main PAU stocks. Fishers gather paua by hand while free diving (use of underwater breathing apparatus is not permitted). Most of the catch is from the Wairarapa coast southwards: the major fishing areas are in the South Island (PAU 7), Stewart Island (PAU 5) and the Chatham Islands (PAU 4).
