-sustainable cities and communities
-quality education
-peace justic and strong intsitutions
- decent works and economic growth
-reduced in eualities
industry, innovaton and infrastrucuture
-climate action
-affordabel and clean energy
what did the resaerch council of norway require concerning faculties of natural science?
- that sustainability aspects will be included in learning goals of all subjects and study programs
what are the main conclusions of the SAFEA report?
- ) the increase of marine food production requires harevsting and production on lower trophic levels of the marine food chain
- )mariculture has and will continue to move prodcution down in the food chain (=potential increase in production )
- ) fisheries will likely not increase as much as mariculture (too conservitiv)
what is SAFEA?
organisation of marine academies
what are the key challenges for sustainable growth of mariculture?
- with the ambition to become as important as agriculture?
-proper environmental management
+ direct influen on marine ecosystem
+influence on remote ecosystem (feed resources)
- stable and attractive working places
- comprehensive knowledge on organisms, farming technology
- economically sustainable companies
- helath and welfare managemnet
- production technology and managemnet for offshore cultivation
what is industyr 4.0?
= subset of the fourth industrial revolution, that concerns industry
introducing:
cyber physical system, smart technologie, internet of things
true or false:
mariculture is among the fastest to integrate industry 4.0 .
true
what does industry 4.0 affects in mariculture?
- farming technologies
- provision of feed resources
- ICT and biotechnology
what are problems we need to face when wanting to make seafood production as important as that from agriculture?
- trophic level challenge of seafood production –> at the moment very inefficient
- fed resource
- cultural heritage
- valuing ecosystem services
- minimising the use of primary procution
where does the trend goes concerning the amount of plant production on land and plant production in the sea
–> they are getting equal
what is THE major challenge for increasing mariculture production ?
primary production in the sea is high, but the yields harvestedt seafood at the end i low!
- low of thermodynamics
- -> so much energy gets lost when going down in the food chain
- —–»»> low efficiency
mariculture: how much of the energy is left at the human trophic level ?
1 percent
99% is lost
why does it not make a big difference, when you fertilize and increase the primary production of mariculture?
because of to the long food chain 99 % gets lost –> doesnt really make difference
how could humans reduce the looses in the marine primary production ?
- culture and consume more seafood from low trophic levels
seaweed base food, mussels, crabs, oyster etc.
what are possible new resources for fish feed?
- single cell biomass (microalgae, bacteria/yeast)
- farmed seaweed (low in fatty acids)
- genetic modified high plants with DHA
