All emerging challenges or diseases.

- programmes that communicate the importance of trout (fish) welfare to different stkeholders

enrichment

Welfare assessment protocols and implementation of surveillance programs for fish welfare in EU

Density, transport and oficial control

Gene expression to stress events

Welfare practical indicators to use in farms

Fish welfare indicators, welfare considerations in context with pre-existing intensive aquaculture in concrete ponds, welfare in context with economic challenges

the possibilities for environmental enrichment with rainbow trouts

Fry/juvenile bacterial infections

I am interested by welfare indicators in farmed fish in general, not only in trout.
Thank you

I am a researcher working with trout in RAS

Opercula shortening and its effect on the fish but specifically the functioning of the gills

Aggression and territory

Fins condition, heart condition

Preventing fin erosion and other injuries. Enviroental enrichment

Vertebral deformities, fin erosion, heart condition

behavior, stress, biochemical and hematological parameters affected by stress

Are there any indicators reflecting positive emotions ?

Assessing stun efficacy

Possibilities for enrichment
Development of contingency plans to protect animal welfare
Welfare requirements for different life stages

Winterfeeding, securing enough space in final growth weeks

stocking density, fin damage, need for structure

The most difficult thing is to identify welware of the fish.

Fin lesions

How to activate fish and give them positive experiences = how to make fish happy?

testosterone use, enrichment- natural behavioural needs, slaughter, milting

- What are best practices for producers (sample size, frequency of different indicators)
- What are the best tools for producers to use to monitor welfare indicators and keep track of them over time?

Fish density in farming (kg/m3) regarding welfare, enrichments in farming

How to asses trout welfare in real life? What kind of tools we should have? Underwater cameras etc.

Biting of fins.

I´m interested in knowing how, as an official veterinarian, I can most easily assess the welfare of rainbow trout in an off shore mesh cage during an inspection. Diving in isn´t really an option. Are there any good cameras that can easily be lowered into the cage to watch how the fish are doing and behaving or is it unlikely that one would get a good view considering water turbulence and visibility? Removing random fish from the cage for inspection? That is in itself a great stress for the individual fish that get caught for inspection.

Easy welfare indicators suitable to various farming methods.

Welfare indicators for pain and suffering in trout

Main issues in fish welfare.
Welfare indicators.
Welfare during slaughter.

Effective stunning systems
Environmental enrichment

fin-biting, exophthalmia, spacing

Animal densities, welfare on slaughter, welfare indicators

Animal transport. Slaughter methods: Animal welfare indicators on farm.

How to carry out welfare inspection on farm, how to observe fish, and if individual fishes are evalueted how should that be done. Scoring of the fin, skin etc.

To find practical (operational) -easy to use- welfare indicators suitable for rainbow trout in diffrent farming environments.

Seeking general information on the welfare assessment in trout.
