Summary
Capture-based aquaculture (CBA) involves wild-caught fish, not genetically adapted to intensive farming. This review assesses fish welfare in CBA, examining key indicators across all farming stages.
Area of Science:
- Aquaculture
- Animal Welfare
- Marine Biology
Background:
- Capture-based aquaculture (CBA) farms wild-caught fish like tuna, eel, and cod.
- Unlike domesticated species, CBA fish lack genetic adaptation to intensive farming conditions.
- This can lead to compromised welfare in CBA systems.
Purpose of the Study:
- To provide an overview of the current state of CBA.
- To focus on assessing fish welfare within CBA systems.
- To discuss commonly used fish welfare indicators in relation to CBA stages.
Main Methods:
- Literature review of existing research on CBA.
- Analysis of fish welfare indicators relevant to CBA.
- Examination of different stages within the CBA process.
Main Results:
- CBA fish welfare is a significant concern due to their wild origin.
- Specific welfare challenges exist at different stages: capture, recovery, and rearing.
- Standard welfare indicators need careful application in the CBA context.
Conclusions:
- Fish welfare in CBA requires dedicated assessment and management strategies.
- Understanding species-specific needs is crucial for wild-caught fish in farming.
- Further research is needed to optimize welfare standards in CBA.
