Why Fish Welfare Matters
Of the estimated 165 billion farmed vertebrate animals alive at any given point globally, 125 billion are farmed fishes. Unfortunately, like other farmed animals, fish are often treated cruelly in the industry. [1]
For the first time, aquaculture—the world’s fastest-growing food industry—has surpassed wild capture as humanity's main source of fishes.
Seafood production: wild fish catch vs. aquaculture, World Aquaculture is the farming of aquatic organisms including fish, molluscs, crustaceans and aquatic plants. Capture fishery production is the volume of wild fish catches landed for all commercial, industrial, recreational and subsistence purposes. 1960 2021 1970 1980 1990 2000 2010 0 t 20 million t 40 million t 60 million t 80 million t 100 million t 120 million t Aquaculture Capture fisheries Data source: Multiple sources compiled by World Bank (2024) OurWorldinData.org/fish-and-overfishing | CC BY
As aquaculture grows, fish welfare must grow, too.
Causes of Suffering
While Welfare Issues Vary In Type And Severity From Farm To Farm, The Broad Causes Of Suffering Farmed Fishes Face Include
Overcrowding
Poor water quality
Ineffective and absent pre-slaughter stunning
Diseases and parasites
Inability to express their natural behaviors
Given salmons’ natural migratory and predatory drives, keeping these animals in sea cages may be fundamentally unsuitable for their welfare. As seen above, salmons may exhibit behaviors such as leaping from the water as they try to remove parasitic sea lice from their bodies. Learn more. Ed Shephard / We Animals
Fish Welfare Improvements
Farmed fishes face a variety of welfare challenges, but some of these
challenges are solvable.

Benefits of Improving Welfare
The welfare of fishes impacts biodiversity, human health, and business sustainability. Improved welfare is the right thing for industry, the environment, and the fishes.

About Us
How FWI Helps Fishes
We research and execute collaborative animal welfare interventions in high-priority contexts. We select these contexts based on the scale of the problem, expected tractability, and other relevant factors.

Our Impact
We work to improve the lives of farmed fishes in two main ways:
Programs
We directly improve the welfare of farmed fishes with our programs. We estimate that we've helped over 5 million fishes so far.
Our Projects
Our Impact
Research and Development
We research new interventions to reduce the suffering of some of the largest and most neglected groups of farmed fishes.

Why We No Longer Count Stocking Density Reductions Towards Our Impact
We have decided to stop counting fishes from eligible stocking density reductions in the ARA as part of our impact. This post explains our decision and why we still keep stocking density limits as part of the program.
