  • Humane Slaughter of Finfish Farmed Around the World
    HSA report February 2018 Humane slaughter of finfish farmed around the world Summary Approximately 360 species of finfish are farmed worldwide and it has been estimated that at least tens of billions of individual farmed fish might be slaughtered every year, which is a far greater number than all the individuals of any other type of farmed vertebrate animal. Finfish are considered capable of experiencing fear and pain and legislation exists in some parts of the world (e.g. the EU) to protect their welfare. Unfortunately, the most common methods of slaughtering finfish (e.g. asphyxia in air or hypothermia in ice slurry) are likely to cause considerable distress. A minority of species (e.g. Atlantic salmon, rainbow trout) in a small number of, mostly European, countries are routinely stunned using higher-welfare methods but there is no one-size-fits-all set of stunning parameters for all species of fish. Funds are required for scientific research and technological development to refine, and to develop new (e.g. SPUC), humane methods of slaughter and to determine humane stunning parameters for a greater range of species of finfish, to suit their various rearing environments and to minimise handling and movement prior to death which can cause stress and chemical and physical deterioration in product quality. Funds are limited, as is legislation requiring stunning of fish at slaughter, and sophisticated stunning equipment is typically expensive, so applying scientific research to improve fish welfare in-practice will likely be a slow process, partly also because the majority of finfish are farmed in countries where the concept of how improved animal welfare can benefit product quality is in its infancy, so finfish species must be prioritised in terms of the greatest outcome.

However, bacterial infections are causing severe mortality episodes. Therefore, there is an urgent need to find an effective management solution. Besides the supplying difficulty and high costs of veterinary drugs in French Polynesia, batfish aquaculture takes place close to the coral reef, where use of synthetic persistent drugs should be restricted. Medicinal plants and bioactive algae are emerging as a cheaper and more sustainable alternative to chemical drugs. We have studied the effect of local Polynesian plants and the local opportunistic algae Asparagopsis taxiformis on batfish when orally administered. Weight gain and expression of two immune-related genes (lysozyme g – Lys G and transforming growth factor beta - TGF-β1) were studied to analyze immunostimulant activity of plants on P.

    Morphometric comparisons of plant-mimetic juvenile fish associated with plant debris observed in the coastal subtropical waters around Kuchierabu-jima Island, southern Japan Alexya Cunha de Queiroz1, Yoichi Sakai2, Marcelo Vallinoto1,3 and Breno Barros1,2,4 1 Instituto de Estudos Costeiros, Laboratório de Evolucão,¸ Universidade Federal do Pará, Braganca,¸ Pará, Brazil 2 Graduate School of Biosphere Science, Laboratory of Aquatic Resources, Hiroshima University, Higashi-Hiroshima, Japan 3 Centro de Investigacão¸ em Biodiversidade e Recursos Genéticos, Universidade do Porto, Vairão, Portugal 4 Campus de Capanema, Universidade Federal Rural da Amazônia, Capanema, Pará, Brazil ABSTRACT The general morphological shape of plant-resembling fish and plant parts were com- pared using a geometric morphometrics approach. Three plant-mimetic fish species, Lobotes surinamensis (Lobotidae), Platax orbicularis (Ephippidae) and Canthidermis maculata (Balistidae), were compared during their early developmental stages with accompanying plant debris (i.e., leaves of several taxa) in the coastal subtropical waters around Kuchierabu-jima Island, closely facing the Kuroshio Current. The degree of similarity shared between the plant parts and co-occurring fish species was quantified, however fish remained morphologically distinct from their plant models. Such similarities were corroborated by analysis of covariance and linear discriminant analysis, in which relative body areas of fish were strongly related to plant models. Our results strengthen the paradigm that morphological clues can lead to ecological evidence to allow predictions of behavioural and habitat choice by mimetic fish, according to Submitted 22 January 2016 the degree of similarity shared with their respective models. The resemblance to plant Accepted 28 June 2016 Published 26 July 2016 parts detected in the three fish species may provide fitness advantages via convergent evolutionary effects.
