Pallisade @Risk software used to optimise Integrated Multi Trophic Aquaculture (IMTA). Aquaculture is a high risk business. Land based aquaculture is no exception but it can lessen some risks compared to other forms of aquaculture. Some of the risks for aquaculture in NZ are:. The biology of most species is not well understood (compared to sheep, cattle and chickens). Disease risk, prevention and/or cure are poorly understood for most species. Long culture periods until harvest (1 5 years). Competition f...

Short finned eel - Anguilla australis). 10 YR NPV - 14% discount rate ($ millions). Freshwater eels (tuna) are found in many river systems and lakes throughout New Zealand. The two native species, the shortfinned and the endemic longfinned eel, are distinguished by the length of their dorsal fin. Shortfin males migrate at an average age of 14 years (38 58 centimetres), females at 22 years (50 100 centimetres). Short finned eel (Anguilla australis). The largest market for eels is Japan. The price of i...

Overview of Land Based Aquaculture » Land Based Aquaculture Assessment Framework
http://www.lbaaf.co.nz/land-based-aquaculture/overview
Aquaculture is the farming of any plant or animal that lives in water. This can be either in seawater, brackish water, or freshwater on land or in the oceans, lakes or rivers. Aquaculture is an agribusiness just as dairy farming or the arable crop farming of maize are. However, unlike the latter two, in general the former is a less developed business type. As such there can be big gaps in our knowledge. Aquaculture New Zealand Overview. Search Aquaculture Fact Sheets. Fisheries and Aquaculture Department.

Intensive land based aquaculture involves increasing stocking density beyond natural food web carrying systems. Raceways with gravity fed or pumped water for growing salmon. (NZ King Salmon). This requires the addition of food and the maintenance of adequate water quality (oxygen, ammonia, nitrate, carbon dioxide, suspended solids, dissolved organic matter and other factors).

Intensive Recirculating Aquaculture Systems (RAS). Recirculating Aquaculture Systems (RAS) reuse the water many times, passing the water through treatment processes to remove waste and to restore water quality. AKVA split loop RAS system. Generic Recirculation System Design. All modern RAS systems generally have the following components;. Solids collection systems (a rotating drum filter). A foam fractionation unit (also known as a protein skimmer or dissolved air floatation device). There are many ways ...

Rainbow trout - Oncorhynchus mykiss). 10 YR NPV - 14% discount rate ( $ millions. Brown trout (Salmo trutta) were introduced from Europe in the late 1860s and established themselves rapidly where they were released. They occur throughout the South Island and lower North Island and spread by going out to sea and swimming up other rivers. Farming trout in RAS units could overcome many of the issues raised since disease risks are reduced and outbreaks could be contained within the RAS should they occur....

Markets for NZ Seafood. Seafood is in great demand mainly because of its healthy image and in particular its luxury niche position amongst other protein sources such as chicken, lamb, beef and pork. Asian fish market (Tsukiji Japan) the world’s largest single fish market. For exports - the New Zealand brand (Pure NZ or similar). World food fish supply (consumption), TOTAL and Per Capita, 2009 (FAO 2012). Auckland fish market a relatively small affair in comparison to Asian fish markets. Top 10 NZ Species.
