New blog post!

The Atlantic mackerel (Scomber scombrus) is a migratory species found in the temperate waters of the North Atlantic and parts of the Mediterranean Seas.

💡 It is one of the most important commercial fish species in the region - about 865,000 tonnes of this mackerel is caught annually, meaning nearly 2 billion individual fishes! It is mainly caught by purse seine fishing.

>> Would you like to know the main fish welfare concerns related to the capture of this mackerel by purse seining? Please, take a look at our new post about that at the blog ConsCIÊNCIA Animal here.

>> You may also access its WelfareCheck profile in the fair-fish database here.

New paper out!

Our team member Caroline M. Maia co-authored a review paper recently published in Fishes Journal. This study highlights the most pressing welfare concerns and challenges in the ornamental fish trade and discusses potential strategies to mitigate its negative impacts on fish welfare. 

💡The authors explore key topics like legislation, gaps in proper information, the welfare of fish in their final destinations and initiatives aiming to improve fish welfare in this trade. They also promote a shift in terminology from 'ornamental fish' to 'pet fish'. It is a small change that reflects a bigger movement toward recognizing these animals as sentient beings.

New Paper Out!

> New paper published!

We believe that solid scientific knowledge is fundamental to practically improving the welfare of fish and other farmed aquatic animals. High-quality publications in this field are the cornerstone of achieving this goal.

💡 In this context, our team member Caroline M Maia co-authored a paper recently published in Journal of Applied Animal Welfare Science. This study examines the preference responses of Nile tilapia for artificial water hyacinth as a structural enrichment, under different stocking densities.

> The authors showed that Nile tilapia expressed a strong preference for this easy-to-build and inexpensive enrichment —especially when kept in crowded tanks. This finding highlights that such artificial structure may be a useful option to improve this fish welfare in farms.

Crucian carp

The crucian carp (Carassius carassius) is a freshwater fish found in lakes, ponds, rivers, and reservoirs across Europe and Asia. Originally farmed in China and Japan, it’s now raised in many countries, often in ponds, pens, or rice fields. Providing plants and soft substrates could help improve its welfare in farms. 

>> If you would like to know more about Crucian carp, please take a look at our new post about this species at blog ConsCIÊNCIA Animal blog here.

>> If you are interested, you can also access its overview page and its WelfareCheck profile in the fair-fish database here and here.

New fish welfare guide published!

Good communication is fundamental to help improving the welfare of farmed fishes in a practical way. Thus, the publication of well-founded fish welfare guidelines are also part of our actions.

💡 Pablo Arechavala-Lopez from our team coordinated the preparation and publication of "A guide on fish welfare in Spanish aquaculture - Volume 4: Welfare of rainbow trout", making another important step toward practical improvements in fish welfare. This publication is the result of the dedicated efforts of a great working group involving several institutions and companies. 

> This work has been financed by APROMAR with co-funding from the Ministry of Agriculture, Fisheries and Food of the Spanish Government and the European Maritime and Fisheries Fund of the European Union.

> If you would like to access the new guideline in English or Spanish, you can access it here.

Participation in a Meeting!

Disseminating science-based knowledge is one of our key activities to help improve the welfare of farmed fishes and other aquatic animals in a practical way. Making presentations at scientific or industry events is also an important part of our efforts to spread the word and share knowledge about fish behaviour and welfare.

💡 As part of this mission, our team member Joao L. Saraiva attended the '25th meeting of the Scientific Network on Risk Assessment in Animal Health and Welfare', which was organized by the European Food Safety Authority (EFSA), in Parma, Italy. João participated online by giving a presentation on a survey of fish husbandry systems in the EU. 

> It was a successful and fruitful opportunity to share our ideas and exchange knowledge.

New Papers Coming Out!

We believe that solid scientific knowledge is fundamental to practically improving the welfare of fishes and other farmed aquatic animals. High-quality publications in this field are the cornerstone of achieving this goal.

💡 Recently, our team members María J. Cabrera-Álvarez and Joao L. Saraiva, along with our students Jose Carlos Campos Sanchez and Inês Cacela Rodrigues, have co-authored two new papers!

The first is a review paper that provides a comprehensive overview of the current findings on neuropeptides in fishes, discussing their potential implications for the physiological and emotional states of these aquatic animals, and therefore, their welfare. This review has been published in the Journal of Comparative Neurology.

The second is a research paper on the preferences of a client reef fish (Chaetodon auriga), demonstrating that it prefers a more blue-saturated cleaner fish (Labroides dimidiatus). This suggests that the blue colouration of cleaners may be a true signal of individual quality. It has been published in the Journal of Experimental Biology.

New podcast episode!

The Fish Mind is a programme of our podcast Fish Talk that is focused on the capacity of fishes to suffer, feel other affective states, and display great cognitive abilities. The idea is to present this important information in an informal dialogue of a few minutes.

💡 We have just released our first episode about positive affective states of fishes in this programme. Did you know that, like humans, fishes may have their own preferences? And these complex responses were already demonstrated to be expressed for several resources or characteristics. This podcast episode is focused on this topic, bringing relevant scientific evidence about fish preferences.

The fruits of our work are making headlines in the media!

Disseminating scientifically-based knowledge is one of our key activities aimed at improving the welfare of farmed fishes and other aquatic animals. So, media coverage of our work plays a crucial role in this.

💡A review paper published in Reviews in Aquaculture and co-authored by our team member Joao L. Saraiva has been showing up in the News. This study examines several crucial water quality parameters in aquaculture, as well as emerging concerns like microplastics and crude oil. By synthesizing the behavioral changes caused by the water quality parameters, this review provides valuable insights for future research, emphasizing the importance of maintaining good water quality for both fish welfare and aquaculture productivity.
