- A Comprehensive Review of Fish Protein Hydrolysates Targeting Pet Food FormulationsPublication . Ribeiro, Tânia Isabel Bragança; Maia, Margarida R.G.; Fonseca, António J.M.; Marques, Bianca; Caleja, Cristina; Rosa, Ana; Martins, Rui; Almeida, André; Mota, Maria J.; Aires, Tiago; Rocha, Cristina M.R.; Teixeira, José António; Cabrita, Ana R.J.; Barros, Lillian; Pintado, ManuelaThe fish industry generates significant amounts of fish by- and co-products (FBCPs) annually, projected to reach 160.8 million tonnes by 2030. This growth highlights the urgent need for sustainable FBCP management and an opportunity to improve the sector’s environmental sustainability. Fish protein hydrolysates (FBCPHs) and bioactive peptides (BPs) derived from these FBCPs are gaining recognition in the pet food sector for their nutritional and bioactives benefits. FBCPHs, primarily sourced from category 3 by-products unsuitable for human consumption, could significantly enhance the economic viability of both industries. This review analyzes production processes, highlighting the benefits and challenges of enzymatic hydrolysis and reviewed emerging technologies such as subcritical water hydrolysis (SWH), which are promising sustainable alternatives by enhancing extraction efficiency and reducing energy consumption. The review explores FBCPHs’ applications in pet food, focusing on beneficial biological activities (e.g. antioxidant, prebiotic, neuroprotective). Findings show FBCPHs have significant potential in pet food formulations, providing palatability, hypoallergenic benefits, and addressing health concerns like gastrointestinal disorders and stress-related behaviors. However, further research is required to optimize production processes, scale industrial application, and ensure regulatory compliance. In conclusion, FBCPHs present a valuable solution for promoting sustainability, improving pet nutrition, and supporting the circular economy.
- Impacts of climate-induced drought on lake and reservoir biodiversity and ecosystem services: a reviewPublication . Sun, Xinyu; Armstrong, Margaret; Moradi, Amirmohammad; Bhattacharya, Ruchi; Geraldes, Ana Maria; Munthali, Elias; Grossart, Hans-Peter; Matsuzaki, Shin-Ichiro; Kangur, Külli; Dunalska, Julita; Stockwell, Jason; Borre, LisaIntensifying extreme droughts are altering lentic ecosystems and disrupting services provisioning. Unfortunately, drought research often lacks a holistic and intersectoral consideration of drought impacts, which can limit relevance of the insights for adaptive management. This literature review evaluated the current state of lake and reservoir extreme drought research in relation to biodiversity and three ecosystem services. The study findings demonstrated that few articles linked or discussed drought implications with one or more ecosystem services, instead focusing primarily on biodiversity. Drought effects on biodiversity varied among species and taxonomic groups. In the limited literature that included ecosystem service provisioning, droughts had a general negative effect. Drinking water supply can decrease and become more costly. Decreasing water flow and volume can reduce hydropower generation. Degraded water quality can also impact recreation. Future intersectoral collaborations and research on intensifying droughts should support adaptive management efforts in mitigating drought impacts.
- Invasive dynamics of the signal crayfish Pacifastacus leniusculus in a protected areaPublication . Carvalho, Francisco; Alves, Henrique; Pascoal, Cláudia; Castro, Paulo; Miranda, Fernando Jorge Veloso; Teixeira, Amílcar; Cássio, Fernanda; Sousa, RonaldoInvasive species have been drivers of biodiversity loss and functional changes in aquatic ecosystems, including in protected areas. Therefore, monitoring population invasion dynamics and biological traits is fundamental to better understand their ecological and economic impacts and for management actions development. We followed signal crayfish (Pacifastacus leniusculus) invasion in Rabaçal River upper reach at Montesinho Natural Park, Portugal. We collected information on the spread and biological traits (abundance, size, weight, physical condition, sex ratio, and aggressiveness) to assess differences between invasion core and front areas and among years. Signal crayfish population remained restricted since first reports in 2013 in the invasion core until 2017. After 2019, signal crayfish population has been spreading downstream, decreasing abundance at invasion core but increasing at invasion front. Significant higher number of crayfish with claw loss indicate potential higher signs of aggressiveness in the invasion front. Results also demonstrate a significant dominance of females although sex ratio is closer to 1:1 at the invasion front. Overall, results indicate signal crayfish is spreading and increasing their abundance at Rabaçal River highlighting the need for immediate management actions to hold dispersion and mitigate possible impacts.
- Old and new climate change adaptation strategies by Montesinho mountain pastoralists, PortugalPublication . Aleixo-Pais, Isa G.; Castro, José; Frazão-Moreira, Amélia; Castro, João Paulo; Castro, MarinaMountain pastoralists are among the communities most affected by climate change, rendering empowerment of mountain communities and supportive policies essential.
