Evaluation on the use of e-learning tools to support teaching and learning in aquaculture and aquatic sciences education

The study aimed to capture a snapshot of the status of educational means used in teaching and learning in the area of aquaculture, fisheries and aquatic resources management at European level, with specific consideration on the use of Information and Communication Technologies and e-learning tools. To achieve this goal, an online survey was compiled and made available to teachers and students across Europe. In total, teachers from 31 institutions and students from 40 institutions participated in this survey. This paper presents the findings, considers trends and poses further questions for sector stakeholders to help in the development of future programmes and support. In summary it can be concluded that few teachers have a comprehensive knowledge of the wide range of ICT tools available and can make use of e-learning tools with complete confidence. There is therefore a real and urgent need to "train the trainers" to use ICT in their teaching environments. From the students' end, there is a strong desire to learn more about the application of e-learning tools and to use them in their learning process.Output from the Aqua-tnet project (EC ERASMUS Thematic Network in Aquaculture, Fisheries and Aquatic Resources Management

Evaluation of larval quality of viviparous scorpionfish Sebastiscus marmoratus

The aim of this study was to develop an acute test for larval quality in the viviparous scorpionfish Sebastiscus marmoratus. Rearing experiments until day 13 post parturition were conducted to investigate the survival of larvae for 13 different batches, and tolerance to starvation of larvae was examined and expressed by the survival activity index (SAI). The morphological characters, enzyme activity, and swimming behavior of larvae on day 0 and 1 were also observed, followed by the correlation analysis between SAI. Larvae with high SAI (?26) showed significantly higher survival on day 13 than larvae with low SAI, which confirmed that SAI is a reliable index that can be used to evaluate larval quality, similar to the former findings. The esterase activity (r = -0.713, P < 0.01), swim frequency (r = -0.735, P < 0.01) and swimming speed (r = -0.588, P < 0.05) of larvae on day 0 were significantly and negatively correlated with SAI. It was concluded that enzyme activity and behavioral characters of larvae just after parturition can be a real-time index for evaluating the larval quality of this species
