57 Question/s: Status of reduction fisheries: - If these fisheries are seen as sustainable what criteria are used - Evidence of ecosystem damage/stress from these fisheries Depends upon definition of sustainability and criteria employed, and who is evaluating the fishery: government, FAO, ICES, NGO (MSC), Industry etc. For example, according to the report of. University of Newcastle/Poseidon Aquatic Resource Management Ltd (2004). The fishmeal & fish oil industry: its role in the common fisheries policy: Management and sustainability of the industrial fisheries `In EU waters most of the targeted feed fish stocks, for which data are available, are considered to be within safe biological limits

58 Question/s: Status of reduction fisheries: - If these fisheries are seen as sustainable what criteria are used - Evidence of ecosystem damage/stress from these fisheries Different views: Huntington, Frid, Banks, Scott & Paramor (2004) Assessment of the Sustainability of Industrial Fisheries Producing Fish Meal and Fish Oil executive summary: `most feed fisheries. are in reasonable condition when considered from the traditional single stock perspective. However there is still only a weak understanding of the relationship between these fisheries and the wider ecosystem, both in terms of 1) their impact on non-target species and the trophic interactions resulting from fishing mortality and 2) the relative importance of climate/oceanography in determining population dynamics

59 Question/s: Status of reduction fisheries: - If these fisheries are seen as sustainable what criteria are used - Evidence of ecosystem damage/stress from these fisheries Different views: Huntington (2004) Feeding of Fish: Sustainable Fish Feed and Scottish Aquaculture synthesis: using a modified MSC-based principles and criteria for sustainable fishing, sustainability. assessment undertaken `preliminary analysis demonstrates that the sustainability of feed fish stocks is still far from certain..concerning the Peruvian anchovy `it is therefore impossible to conclude whether this fishery is sustainable or not

60 Is theremarine sufficient Aquaculture research Task onforce the sustainability Meeting of Jan reduction 19-21, 2006 fisheries to certify Issue: them? Feeds & Nutrition Aquafeeds & Reduction Fisheries As mentioned previously, this depends upon the definition of sustainability employed and criteria and indicators used. As mentioned in the SEAFEEDS (2003) report concerning the sustainability of feed grade fisheries: `There is a lack of agreed criteria and integrated reporting systems for the broader dimensions of sustainability relating to effects. on other fisheries and wider ecosystem and socio-economic impacts... we currently lack the information to make broader assessments of sustainability taking account of wider socio-economic and ecosystem impacts There is an urgent need to develop appropriate internationally agreed sustainability standards and criteria for feed-based fisheries at present these exist for `Sustainable Fishing (MSC) and `Indicators for Sustainable Development of Marine Capture Fisheries (FAO, 1999).

61 Question/s: Potential for use of fishery byproducts for minimizing demand on reduction fisheries - Are the `by-product product fisheries sustainable and does focusing more pressure on them create incentives for more bycatch, or pressure on the sustainability of the target fisheries? Industry estimates that there were 5.6 million tonnes of trimmings and rejects from food fish in 2002 (FIN, 2004).. For example, within the European Union (EU) it is estimated that in 2002 about 33% of the fishmeal produced in the EU-15 was manufactured from trimmings from food fish processing, including Spain 100% trimmings, France 100%, Germany 100%, Italy 100%, UK 84%, Ireland 60%, Sweden 25%, and Denmark 10% (Huntington et al. 2004). As mentioned previously, no information is currently available from FAO concerning the total global production of fishmeals and oils produced from fishery and aquaculture trimmings and offal. Clearly this deficiency needs to be rectified.

64 Question/s: Potential for use of fishery byproducts for minimizing demand on reduction fisheries - Are the `by-product product fisheries sustainable and does focusing more pressure on them create incentives for more bycatch, or pressure on the sustainability of the target fisheries? Report: SCAHAW (2003): The use of fish by-products in aquaculture. Report of the Scientific Committee on Animal Health & Animal Welfare; Adopted 26 February 2003 In most European countries the fishmeal Industry is the major receiver of by-products from traditional fisheries, followed in importance by the ensiling of by-products.. With regard to aquaculture, by-products also arise from the slaughter and processing of fish for human consumption, including farmed salmon.

65 Question/s: Potential for use of fishery byproducts for minimizing demand on reduction fisheries - Are the `by-product product fisheries sustainable and does focusing more pressure on them create incentives for more bycatch, or pressure on the sustainability of the target fisheries? As stated previously, there is a need for the aquafeed industry to utilize the largely untapped existing waste streams within the fisheries sector, including fisheries bycatch and discards (Alverson et al. 1994:. recently estimated at over 7 million tonnes) and fishery processing wastes (Bechtel, 2003; Li et al. 2004; Rathbone et al. 2001); Moreover, as stated in the FAO Code of Conducted for Responsible Fisheries (FAO, 1995) `States should encourage the use of fish for human consumption and promote consumption of fish whenever appropriate, and discourage the use of food-fish fit for human consumption for animal feeding;

66 Question/s: Potential for use of fishery byproducts for minimizing demand on reduction fisheries - Are the `by-product product fisheries sustainable and does focusing more pressure on them create incentives for more bycatch, or pressure on the sustainability of the target fisheries? There is no simple answer to the above question: Fristly, we do not have a full grasp on. the exact size of the by-product fisheries and sustainability of these food fishing operations; Secondly, feed manufacturers require consistency in the quality of their feed ingredient sources, and the quality and freshness of fishery byproducts can be highly variable depending upon fishing/processing method employed, season, target species composition and nature of the product (heads, guts, skin, frames, spoiled fish etc.) processed.

75 Status of fisheries & ecosystem impacts from fishmeal and oil use -Key questions that have yet to be resolved Need to develop internationally agreed standards, principles and criteria for sustainable feed-based fisheries. In line with the FAO Code of Conduct for Responsible Fisheries, the special needs of Developing Countries need to be taken into consideration when developing these standards and criteria; On the basis of the above agreed standards, principles and criteria for FAO/MSC or appropriate NGO to then ascertain the sustainability of the major reduction fisheries; Need to estimate total global production of fishmeal and fish oil from fishery by-products and trimmings, including species composition; Need to develop models concerning energy consumption within the different major reduction fisheries, including fishing, meal/oil manufacture

76 Question: : Status of the development and use of dietary fishmeal and oil substitutes for marine species Like humans, fish have a specific dietary requirement for 40 or so essential dietary nutrients and do not have a specific dietary requirement for a particular ingredient such as fishmeal or fish oil. For example, in their natural environment, the diet of salmonids consists of a mixture of crustaceans, molluscs and to a lesser extent fish; Not withstanding the above, fishmeal and fish oil has a nutritional profile which approximates closest to the known dietary requirements of fish, and as such usually has a high biological value and digestibility for farmed fish if prepared from fresh fish and processed adequately

77 Question: : Status of the development and use of dietary fishmeal and oil substitutes for marine species Current issues and obstacles to FM/FO usage are mainly ECONOMIC and MARKET DRIVEN: - Limited fish stocks & increasing fishing controls (biological limit) - Increasing proportion used for direct human consumption - Increasing competition for finite static resource - Increasing fishmeal & fish oil prices - Decreasing farmed fish prices due to increased production - Increasing farm production costs & overseas competition - Increasing demand by consumers for cleaner & greener foodstuffs

78 Constraints to using fishmeal and fish oil within aquafeeds: Mainly economic & market driven: - Limited fish stocks & increasing fishing controls (biological limit) - Increasing proportion used for direct human consumption - Increasing competition for finite static resource - Increasing fishmeal & fish oil prices - Decreasing farmed fish prices due to increased production - Increasing farm production costs & overseas competition - Increasing demand by consumers Solution: ON-GOING FOR ALL FEED MANUFACTURERS - Reduction of levels of usage on purely economic grounds - Increased use of alternative dietary proteins & lipids - Development of Improved feed & food safety controls - Development of greener feeds & farming systems

99 Animal by-product meals (ca million tonnes/annum, dry basis) exceed that of fishmeal and fish oils (6-8 million tonnes/annum, dry basis) by a factor of two to three and represent the largest source of animal proteins and lipids currently available in the market place for animal feed industry, including the salmon aquafeed sector. Action required: - Consumer education regarding the safety of using adequately processed rendered animal products within aquafeeds, including salmon feeds. - Change of EU legislation allowing the use of rendered protein and lipid sources within aquafeeds - The increased use of rendered products within aquafeeds is typified by the lower levels of fishmeal currently used in salmon feeds in Canada - Aquaculture, and in particular MARINE FISH FISHING, should be viewed as the recycler of feed-grade rendered animal by-products into

116 Summary-techniques for reducing POPs The selective use of marine oils with natural lower level of organic pollutants will reduce the level of dioxins in farmed fish, however, to a lesser extend the level of dioxin like PCB s and even less on PBDE. The use of vegetable oils will effectively reduce the level of all three mentioned organic pollutants, however, will also affect nutrients (n-3 HUFA) normally rich in marine fish. The use of cleaning techniques might be a promising approach in reducing the level of organic pollutants and maintaining the high nutritional value of seafood.

117 The substitution of marine feed ingredients with alternative ingredients might introduce new threats for food safety For GM, substitution of fish meal with plant meal had no apparent negative effect on fish health or forms a risk for the consumer In developing novel feeds for the production of a safe and healthy seafood a combination of both reduction of undesirables components and maintenance of health benefit nutrients has to be achieved.

129 Key questions Question/s: that have yet Public to be health researched? issues related to feed - Assessment of environmental contaminant levels within the reduction fisheries stocks of the North, Central & South Pacific - Comparative global assessment of environmental contaminant levels within wild marine food fish stocks, including salmon, tuna, sword fish, cod, haddock - Publication of research findings on contaminant levels within fish stocks, including relevant feeding/spot-check analytical studies with farmed salmonids, within high profile peer reviewed non-aquaculture journals, including key medical and environmental science journals - Need to promote the nutritional health merits of farmed salmon (and seafood in general), not only as a source of omega-3 fatty acids, but also as a source of high quality animal protein and essential minerals and vitamins: we have a serious global food/obesity problem and have a solution in our hands

130 /s: Need to publish in aquaculture journal & non-aquaculture peer reviewed journals Question/s:

131 /s: Feed/feeding and ecosystem Question/s: Does feeding potentially contribute to additional contaminant loading around net cages? -Of course the answer is yes, and this may include additional contaminant loading from uneaten feed, fish faeces and excreta. -The potential impact (negative or positive) of these contaminants around the cages will depend upon the environmental carrying capacity of the coastal zone/area where the cages are geographically located and the water depth/water current under the cages. -Whilst in the past these contaminants have been considered in a negative sense, these so called contaminants are really `nutrients and as such could be harnessed for the co-culture of associated filter feeding species (ie. mussels) and aquatic plants (ie. seaweeds) rather than just released into the open sea.

137 There is no doubt that the third millennium will herald marked changes in ALL our global food production systems, including: Aquaculture

138 The over-riding riding reason for these changes is the stark realization (after years of environmental abuse) that our PLANET has it s LIMITS, both in terms of it s s available natural resources (land, water, energy, nutrients, biota), and through earth s ability and capacity to RECYCLE these resources and sustain LIFE as we currently know it.

139 Through the activities of our societies, food production sectors & industries we are now negatively impacting the land that we live on, the food that we eat, the water that we drink, the air that we breath, to the weather & climate of our planet and the well-being & health of ALL living things

140 The upshot of this is that AQUACULTURE, like all other food production systems, will have to become increasingly more ENVIRONMENTALLY & ECOLOGICALLY RESPONSIBLE if it is be truly sustainable in the long run and be socially accepted as an economically viable means of producing much needed high quality food for an ever increasing & hungry population

141 MALNUTRITION is still the number one killer & cause of suffering on earth; causing more deaths than HIV/AIDS, warfare, genocide, terrorism, or any other ailment

142 Every minute of every day, especially within developing countries, 23 children die of malnutrition and preventable diseases. Even when it doesn't kill, chronic malnutrition can cause blindness, birth deformities and brain damage. By the end of my 60 minute presentation 1,380 children will have died

143 It is estimated that about one-fifth of the world s s population is currently living in extreme economic poverty; ; defined as living on less than US$ 1 per day

144 The above tragedy is a particular travesty bearing in mind MALNUTRITION: the over-supply and imbalance of nutrients and consequent global epidemic of obesity which is occurring, especially within industrialized countries: resulting in decreased productivity and increased risk of heart disease, hypertension, stress, diabetes and certain cancers.
