Research & Resources
We are currently conducting research to shape our future interventions. Below is an overview of our research, as well as selected reports and papers that we find particularly helpful. Also included are resources for those interested in learning more about fish welfare and advocacy.
We welcome questions and feedback. To do this, please contact us.
Shorter pieces can be found on our blog.
Aquaculture in Asian Countries
Fish production in Asia is growing fast and this adds a wide range of welfare problems. Tapping into a dynamic industry, now is an important time to explore high leverage opportunities for fish welfare work.
Fish Welfare Scoping Report: India
India is the second largest producer of finfish in the world. Combining FAO and industry data, as well as the findings from our farm visits, this report analyzes the current state and future potential for fish welfare in Indian aquaculture.
Fish Welfare Improvements in Aquaculture
Fish Welfare is a topic gaining global recognition. While fish are at the center of this, the value of improving fish welfare extends far beyond the fish themselves. This report can help equip all stakeholders in fish welfare with the relevant knowledge to best address fish welfare.
Different fish species have dramatically different welfare needs. This report proposes a prioritization process for identifying the species most promising to work with, and provides some tentative conclusions amongst species commonly farmed in Asia.
In this report we review various approaches an organization can take to improve welfare for farmed animals. For each, a summary is given, as well as a list of pros and cons, crucial considerations, and its long term promise.

SELECTED EXTERNAL RESEARCH
Farmed Fish Overview Reports
Briefing that covers health problems and disease, handling, stocking density, breeding methods, genetic selection and genetic engineering and farming of new fish species.
This report covers considerations relevant to determining appropriate indicators of farmed fish welfare. It also discusses potential reforms to improve the welfare of farmed fishes.
This report reviews the scientific data that allows us to interpret the effects of disease, handling, transport, food deprivation, and slaughter technique on fish welfare.
Aquaculture practices and production—including handling, grading, transport, genetic manipulation, aggression from conspecifics, predation, physiological stress, and inhumane slaughter—compromise the welfare of fish.
This report provides an overview of the extent to which fish welfare might be impacted within the aquaculture industry, by describing the main processes of fish farming and their associated welfare implications.
Wild-Caught Fish Overview Reports
This report looks at the welfare of fish in commercial fishing. Considerable suffering is caused to wild-caught fish during capture, landing, and subsequent processing.
Other Selected Research
Unnaturally high juvenile mortality and poor reporting in aquaculture hatcheries are among the main findings of Dyrevernalliansen and the Norwegian Veterinary Institute's project "Småfiskvel".
This paper aims to merge what is already known about positive welfare with the existing fish behavior literature to develop a plan of action for fish welfare research that will ultimately contribute to the development of positive welfare standards and assessment strategies for fish.
The effects of domestication on welfare of farmed fishes are complex to study because fish differ from livestock in genetics, physiology and behaviour, and experience different sensory worlds. The implementation of humane farming systems should integrate industry, science and ethics in an open dialogue in order to produce relevant results.
There is a growing body of scientific evidence demonstrating that fish are sentient animals – capable of effective states of pain, fear and psychological stress and examples of impressive cognitive abilities and complex social behaviours are widespread. We therefore have a moral obligation to protect their welfare
This report shines a spotlight on the environmental and social impacts of reduction fisheries, i.e. the use of wild-caught fish in fishmeal and fish oil (FMFO) to feed farmed fish.
Octopus farming is in an experimental phase and supported by various countries. This report argues that it is unethical because of concerns about animal welfare as well as environmental impacts.
This article is a part of a series of articles by Rethink Priorities about animals farmed for various purposes. The report addresses the welfare problems related to fish stocking.
