Mejora de las competencias gracias a la implantación de aprendizaje basado en proyectos en acuicultura - [Improve of competences through project-based learning in aquaculture]

Innovaciones docentes en tiempos de pandemia. (2021)

David S. Peñaranda Ignacio Jauralde-García Ana Tomás‐Vidal Miguel Jover‐Cerdá Silvia Martínez‐Llorens

En el presente trabajo se muestra la experiencia de la aplicación del Aprendizaje Basada en proyectos (ABP) en la asignatura “Diseño y Gestión de instalaciones Piscícolas” de la titulación del Máster interuniversitario de Acuicultura de la Universitat Politécnica de València. El ABP consistió en el desarrollo de un proyecto de una piscifactoría, en el cual los alumnos debían integrar los conocimientos adquiridos en las asignaturas previas, permitiendo una visión más multidisciplinar de la asignatura y mejor adquisición de las competencias. Tanto desde el punto de vista del alumnado como del profesor, la implantación del ABP permitió un mayor desarrollo de las competencias, siendo la metodología docente valorada positivamente. Además, se mejoró la participación del alumnado en las actividades propuestas, dando como resultado una mejor calificando académica final. No obstante, se deben de mejorar algunos aspectos como es la planificación del tiempo y consolidar relaciones de integración o la interacción entre diferentes disciplinas/asignaturas de manera que tengan una mejor integración en el proyecto.

Growth, Survival, and Intestinal Health Alterations in Mediterranean Yellowtail (Seriola dumerili) Due to Alternatives to Fishmeal and Fish Oil

Current Issues in Molecular Biology (2024)

María Consolación Milián-Sorribes Silvia Martínez‐Llorens David S. Peñaranda Ignacio Jauralde Miguel Jover‐Cerdá

Fishmeal and fish oil substitution in aquafeeds might have adverse effects on fish growth and health, mainly in carnivorous species, such as Mediterranean yellowtail (Seriola dumerili). Mediterranean yellowtail shows great potential as an alternative aquaculture species due to its fast growth and high price on the market, but the need for high-quality protein and fatty acid content in its diets is limiting its production. In order to improve the sustainability of its production, this study was conducted with 360 fish of 35 g to evaluate the effects on fish growth and health. Six diets were used: one control diet without replacement, three with FM replacement (FM66, FM33, and FM0) (33%, 66%, and 100% FM replacement), and two with FO replacement (FO50 and FO0) (50% and 100% FO replacement). The substitution of FM was with vegetable (VM) (corn gluten) and animal (AM) (krill and meat meal) meals. The reductions in FM and FO of up to 33 and 0%, respectively, did not affect the growth and survival of S. dumerili at the intestinal morphology level, except for the anterior intestine regarding the lower villi length and width and the posterior intestine regarding the lower width of the lamina propria. On the other hand, the substitution of fish ingredients in the diet affects liver morphology, indicating alterations in the major diameter of hepatocytes or their nuclei. Finally, diet did not affect the gut microbiota with respect to the control, but significant differences were found in alpha and beta diversity when FO and FM microbiota were compared. A 66% FM replacement and total FO replacement would be possible without causing major alterations in the fish.

Successful Inclusion of High Vegetable Protein Sources in Feed for Rainbow Trout without Decrement in Intestinal Health

Animals (2021)

Glenda Vélez‐Calabria David S. Peñaranda Miguel Jover‐Cerdá Silvia Martínez‐Llorens Ana Tomás‐Vidal

The aquaculture of carnivorous fish is in continuous expansion, which leads to the need to reduce the dependence on fishmeal (FM). Plant proteins (PP) represent a suitable protein alternative to FM and are increasingly used in fish feed. However, PP may lead to stunted growth and enteritis. In the current study, the effect of high FM substitution by PP sources on the growth, mortality and intestinal health of rainbow trout (Oncorhynchus mykiss) was evaluated in terms of the histological intestine parameters and expression of genes related to inflammation (IL-1β, IL-8 and TGF-β) and immune responses (Transferrin, IgT and IFN-γ). The results show that a total substitution registered lower growth and survival rates, probably due to a disruption to the animal's health. Confirming this hypothesis, fish fed FM0 showed histological changes in the intestine and gene changes related to inflammatory responses, which in the long-term could have triggered an immunosuppression. The FM10 diet presented not only a similar expression to FM20 (control diet), but also similar growth and survival. Therefore, 90% of FM substitution was demonstrated as being feasible in this species using a PP blend of wheat gluten (WG) and soybean meal (SBM) as a protein source.

Replacement of fish oil with vegetable oil blends in feeds for greater amberjack (Seriola dumerili) juveniles: Effect on growth performance, feed efficiency, tissue fatty acid composition and flesh nutritional value

Aquaculture Nutrition (2017)

Raquel Monge‐Ortiz Ana Tomás‐Vidal Deiene Rodríguez‐Barreto Silvia Martínez‐Llorens José A. Pérez

This study was undertaken to assess the effects of fish oil (FO) substitution by a mixture of alternative vegetable oils (VO) on Seriola dumerili culture performance. A 154-day feeding experiment was conducted using juveniles (39.2 ± 1.6 g average weight). Three isolipidic and isoenergetic meal-based diets were formulated varying their lipid component. The control diet contained 100% FO (FO100), whereas diets VO50 and VO100 included 1/2 of oil blend and all the oil from blend of palm oil (PO) and linseed oil (LO) as substitute for FO, respectively. Dietary regime did not significantly affect growth performance, biometric indices, feed efficiency, plasma chemistry and liver and muscle lipid contents. Nonetheless, dietary VO inclusion impacted on the fatty acid profile of target tissues, especially in the liver. Fatty acid profiles of the fillets reflected those of the dietary oils except that there was apparent selective utilization of palmitic acid (C16:0) and oleic acid (C18:1n-9) and apparent selective retention of long-chain polyunsaturated fatty acids, especially eicosapentaenoic acid (EPA, C20:5n-3) and docosahexaenoic acid (DHA, C22:6n-3). The nutritional value and the potential ability to prevent the development of coronary heart diseases of the flesh lipid fraction decreased with gradual FO substitution.

An Approach to the Spanish Consumer’s Perception of the Sensory Quality of Environmentally Friendly Seabass

Foods (2021)

Juan Calanche Ana Tomás‐Vidal Edilson Ronny Cusiyunca-Phoco Silvia Martínez‐Llorens Pedro Marquina

Seabass is one of the leading aquaculture species in Europe. Sensory analysis is essential for new product development. This research focused on establishing and differentiating the opinion of consumers about seabass quality obtained with organic feeding. Fish were fed for 196 days with four treatments (a control diet with 30% fishmeal and three diets with different levels of fishmeal supplemented with organic vegetable ingredients: 25%, 30% and 35%). Experimental diets were compared with commercial samples from the retail industry that were considered as "adequate quality for fish". Two sensory analyses were carried out, check-all-that-apply (CATA) to obtain feedback on consumers' characterization towards a different type of fish evaluated and projective mapping (PM) to measure the similarity among a set of products and establish a comparison between results provided by both methods. According to the CATA results, white color, softness, meaty taste and juicy texture were considered relevant attributes, also showing a good relationship with an adequate cooked fish description. A penalty analysis confirmed that the previous characteristics were considered essential while fibrous was an undesirable attribute. The projective mapping showed a similar sensory configuration to the CATA, corroborating these findings that showed that commercial fish were placed in a position away from the rest of the treatments, and the organic diet with a higher level of fishmeal (35%) was the most distant from the control diet.

Cumulative climatic stressors strangles marine aquaculture: Ancillary effects of COVID 19 on Spanish mariculture

Aquaculture (2021)

Pablo Sánchez-Jérez José M. F. Babarro X. A. Padín Angeles Longa Portabales Silvia Martínez‐Llorens

Marine aquaculture takes advantage of marine ecosystem services to produce goods that can be relevant from a food security point of view. However, this activity is subject to multiple stressors as the ones exerted by global climate change. Local stressed conditions due to environmental drivers may be exacerbated by the COVID19 pandemic crisis. In this paper we analyze the pre-COVID-19 situation in two Spanish regions with the highest aquaculture production, Galicia and the Valencian Community. The incidence of storms, heat waves and mussel farming closure were analyzed, and surveys were used to define the perception of producers in terms of economic problems derived from COVID-19 and synergistic environmental concerns. Also the temporal trend of mussel production was analyzed. Spanish marine aquaculture has been intensively subjected to climatic stressors that made it more vulnerable to COVID-19, showing some weakness in terms of production as can be seen in mussel production and fresh consumption. Anyway, extensive aquaculture and aquaculture developed by Integrated Multi-Trophic Aquaculture (IMTA) was reported as somewhat more resilient to the impact of COVID-19. In order to ensure the environmental and economic sustainability of marine aquaculture - under a future uncertain pandemic scenario – our outcomes underline the need for more resilient adaptation programs and recovery plans taking into account the climate change effects.
