In this module, we learned that the ocean plays a vital role in ensuring food security, and moreover that fisheries and aquaculture need to be better managed if we want the ocean to continue being…

This chapter deals with economic solutions to the global over-fishing problem. The fundamental problem of marine fisheries from an economic point of view is that there is a price for fish on land, so…

This lecture is about marine aquaculture, the fastest growing food sector in the world. You will learn in this lecture that eating tuna is actually like eating a wolf-eater, if it was an equivalent…

Learning about marine food webs is essential to understand how the ocean provides us with seafood. Enjoy the whiteboard animation before watching Chapter 4.2 "Dance of the Plankton." This…

This live Q&A session took place on May 14, 2020, and answered questions related to the UN Decade of Ocean Science, ocean governance, ocean literacy, and the impact of COVID-19 on the ocean. …

This lecture looks at human interaction with oceans and aquaculture, and the adverse effect it has had on marine ecosystems and well as fisheries. This video is not available under a Creative…

This chapter discusses aquaculture for nutrition security, which raises questions such as, do we need fish? Can we supply sufficient seafood for future populations? Can we do so in a responsible…

Biodiversity is an important planetary boundary because, without the living species, we would not have biomass, carbon sequestration, rainfall, or the regulation of the flow of fresh water, carbon,…

Terrestrial ecosystems have very close connections with inland freshwater ecosystems in terms of both flora and fauna; to protect a fishery, protect a flooded forest. Forests that occur alongside…

This chapter discusses why ocean circulation is changing, the variabilities in monsoon systems, and the El Niño phenomena. Ocean circulation responds to the amount of sunlight on the ocean…

In the period from 1950 to the late 1980s, global catches in fishers have increased from less than 20 million tons per year to about 80 million tons per year. They have not increased anymore, which…

In this chapter Martin Quaas gives some arguments for an economic solution to the global overfishing problem. The fundamental problem is that there is a price for fish on land once it is harvested,…

Most of marine aquaculture is not sustainable and is actually taking away protein from the human population. Around 1990, the wild capture fisheries leveled off at 95 million metric tons per year…
