Potential effects of mussel farming on New Zealand"s marine mammals and seabirds by Lloyd, Brian Download PDF EPUB FB2

Potential effects of mussel farming on New Zealand’s marine mammals and seabirds: a discussion paper. Bryde’s whale (Balaenoptera edeni) found dead after entanglement in a mussel spat catching farm, Great Barrier Island, August A spat catching line is caught around the whale’s jaw and body.

The only reported adverse effects of mussel cultivation on marine mammals or seabirds in New Zealand are the exclusion of dusky dolphins from mussel farms (Markowitz et al.

in press), and the entanglement and deaths of two Bryde’s whales in mussel spat-catching lines. Title: Potential effects of mussel farming on New Zealand’s marine mammals and seabirds: a discussion paper Author: B.D.

Lloyd Subject: SIN The effects of marine farming on marine mammals and seabirds are not fully understood although there have been many reports and evidence presented.

Potentially marine farms could adversely affect such species if they reduce or block access to food sources, limit the space available for hunting, or interfere with normal behaviour such as migratory routes. Advice was also taken from the document “Poten tial Effects of Mussel Farming on New Zealand’s Marine Mammals and Seabirds”,DOC.

Marine mammals buffer Environment Bay of Plenty contracted a marine mammal expert to prepare a report for council called “The sensitivity of marine mammals found in the Bay of Plenty to aquaculture activities”. This. range of potential species suitable for marine culture could include sponges, seaweeds, crustaceans and fish.

Marine farming can only occur within Aquaculture Management Areas (AMA) identified in a Regional Coastal Plan. There is. Conversely, they can negatively affect seabirds through entanglement, disturbance and loss of habitat.

However, the footprint of fish farms on seabird habitat would be very small, so any effects are likely to be minor. Fish farms can affect marine mammals through entanglement, habitat exclusion, and disturbance by vessel strikes and underwater. farm appear to provide for the avoidance or minimisation of these potential adverse effects.

Any adverse effects on seabirds are likely to be less than minor and there is the potential for mild positive effects in terms of roosting sites and for piscivorous seabirds. Adverse effects on marine mammals are unlikely and the potential for entanglement.

Marine mammals, seabirds, and shorebirds are indicator species for the state of our marine environment. New Zealand has a marine area of more than 4 million km 2.

Reporting on the different environments within our marine waters helps us understand the overall state of the marine domain.

This industry produces overtonnes annually and in was valued in excess of NZ$ million. The aquaculture of the New Zealand greenshell mussel relies heavily on the production of mussel seed, or spat, by wild mussel : Mytilidae.

Using a risk-based approach, the ecological significance of each of these issues was evaluated in aquaculture, and especially mussel farming. Aquaculture is the general term given to the cultivation of any fresh or salt water plant or animal.

Protecting seabirds and marine mammals New Zealand is seabird central. More species of seabirds – notably albatross, petrel, penguin and shag species –breed in New Zealand than anywhere else in the world.

That is why it is beholden on the fishing industry to minimise its impact on creatures we all value. fisheries and marine mammals in New Zealand waters.

Department of Conservation, The only reported adverse effects of mussel cultivation on marine mammals or seabirds in New Zealand are the exclusion of dusky dolphins from mussel farms (Markowitz et al.

Marine Mammals and Noise: A Sound Approach EXECUTIVE SUMMARY Human activities are increasing the level of sound in the oceans, causing widespread concern about potential effects on marine mammals and marine ecosystems.

In addition, a National Oceanic and Atmospheric Administration workshop (Moore and Wieting, ) explored broader interactions between mariculture and marine mammals and marine turtles, and a discussion paper on the potential effects of mussel farming on marine mammals and seabirds was produced by the New Zealand Department of Conservation.

Protected species include almost all New Zealand seabirds, all marine mammals, some marine reptiles, black and some red corals, black-spotted groper, and white pointer sharks.

Fishing has the potential to affect all of these groups through incidental capture or damage, habitat modification, competition effects, or other indirect effects. The New Zealand green-lipped mussel, (also known as Perna canaliculus, the New Zealand mussel, the greenshell mussel, kuku, and kutai) is a bivalve mollusc in the family Mytilidae.

P. canaliculus has great importance as a cultivated species for New Zealand.Seabirds (also known as marine birds) are birds that are adapted to life within the marine environment. While seabirds vary greatly in lifestyle, behaviour and physiology, they often exhibit striking convergent evolution, as the same environmental problems and feeding niches have resulted in similar adaptations.
