‘Aquafeed 3.0’: creating a more resilient aquaculture industry with a circular bioeconomy framework

Stefanie M. Colombo & Giovanni M. Turchini, Reviews in Aquaculture Fisheries & Aquaculture

As aquaculture continues to grow, so does the requirement for environmentally sustainable and cost‐effective aquafeed. With an expected increase in aquafeed demand, it is important (now more than ever) to investigate and utilize new aquafeed ingredients that do not deplete natural resources and, instead, may have positive impacts to help control climate change.

A case for seaweed aquaculture inclusion in U.S. nutrient pollution management

Racine, P. et al., Marine Policy Fisheries & Aquaculture

Seaweed aquaculture is capable of removing large quantities of nitrogen and phosphorus from coastal ecosystems, yet seaweed has gained little traction for its potential role in targeted nutrient assimilation.

A 20-year retrospective review of global aquaculture

Naylor, R.L. et al., Nature Fisheries & Aquaculture

The sustainability of aquaculture has been debated intensely since 2000, when a review on the net contribution of aquaculture to world fish supplies was published in Nature. This paper reviews the developments in global aquaculture from 1997 to 2017, incorporating all industry sub-sectors and highlighting the integration of aquaculture in the global food system.

Exploring the future of fishery conflict through narrative scenarios

Spijkers, J. et al., One Earth Fisheries & Aquaculture

Disruptive changes in our global ocean and fisheries have sparked warnings of an increase in fishery conflicts. However, such environmental changes have not yet been considered in tandem with other critical social, economic, and political trends for mapping out possible future trajectories for fishery conflict.

Red seaweed (Asparagopsis taxiformis) supplementation reduces enteric methane by over 80 percent in beef steers

Roque, BM et al., PLoS ONE Energy Solutions Fisheries & Aquaculture

Livestock production, particularly ruminants, contributes to anthropogenic greenhouse gas (GHG) emissions globally. These emissions are estimated to be 7.1 Gt carbon dioxide (CO2) equivalents annually which accounts for approximately 14.5% of the global anthropogenic GHG emissions. The majority of GHG emissions from livestock production is in the form of methane (CH4), which is produced largely through enteric fermentation and to a lesser extent manure decomposition.

The Outlaw Ocean: Business and Technology Solutions that Address Illegal Fishing and Labor Abuses in Seafood Supply Chains

Stanford Center for Ocean Solutions (COS) and the Stanford Law School (SLS) Fisheries & Aquaculture Shipping & Ports

Illegal, unreported and unregulated (IUU) fishing is a complex, systemic issue with impacts that resonate through global supply chains and can particularly harm those most vulnerable: the workers on fishing vessels. The millions of tons of fish stolen each year result in a huge loss to the economies of coastal nations and a threat to food security for the billion people who depend on fish for protein. Additionally, vessels that fish illegally often engage in labor abuses, including everything from substandard working conditions to modern slavery, prompting a human rights crisis.

Effects of depth-cycling on nutrient uptake and biomass production in the giant kelp Macrocystis pyrifera

Navarrete, I.A. et al., Renewable and Sustainable Energy Reviews Fisheries & Aquaculture

Seasonal or chronic nutrient limitations in the photic zone limit large-scale cultivation of seaweed (macroalgae) in much of the world's oceans, hindering the development of macroalgae as a biofuel feedstock. One possible solution is to supply nutrients using a diel depth-cycling approach, physically moving the macroalgae between deep nutrient-rich water at night and shallow depths within the photic zone during the day.
