Health screening and autogenous vaccination strategies for atypical Aeromonas salmonicida in farmed ballan wrasse (Labrus bergylta, Ascanius) See

Ballan wrasse (Labrus bergylta, A.) are deployed in Atlantic salmon (Salmo salar, L.) pens to control sea lice (Lepeophtheirus salmonis, K) infestations in the Northern hemisphere. Bacterial disease outbreaks related to atypical Aeromonas salmonicida (aAs), however, cause significant mortalities in ballan wrasse at hatcheries and cage sites. Although a multivalent autogenous vaccine, including aAs, was being used disease outbreaks still occurred. The aims of this project were initially to ide...

Individuals differ in how they cope with stressful situations along a behavioural continuum, being proactive and reactive at the extremes of this continuum. Proactive individuals are usually bold, highly active and take risks, while reactive organisms are generally shy, exhibit low activity and avoid risky situations. Definitions of stress coping styles state that proactive and reactive traits are consistent over time and across contexts. The present study evaluated the individual differences...

Individual stress coping style (reactive, intermediate and proactive) was determined in 3 groups of 120 pit tagged European seabass using the hypoxia avoidance test. The same three groups (no change in social composition) were then reared according to the standards recommended for this species. Then, 127 days later, individuals initially characterized as reactive, intermediate or proactive were submitted to an acute confinement stress for 30 min. Blood samples were taken to measure plasma cor...

Nor A, Gray TS, Caldwell GS & Stead SM (2019) A value chain analysis of Malaysia’s seaweed industry. Journal of Applied Phycology. https://doi.org/10.1007/s10811-019-02004-3 See

A global shortfall in protein supply from capture fisheries has motivated the Malaysian government to revise its aquaculture strategy, focusing on three commodities: seaweed, fish and marine shrimp. However, the performance of the Malaysian aquaculture sector, particularly seaweed production, is poorly documented. This is the first empirical study to undertake a value chain analysis (VCA) of the Malaysian seaweed sector using stakeholder perceptions and secondary data that encompass members o...

Oliveira CCV, McStay E, Cabrita E, Castanheira MF, Migaud H, Dinis MT & Davie A (2020) Investigating the kisspeptin system in the hermaphrodite teleost gilthead seabream (Sparus aurata). Comparative Biochemistry and Physiology Part A: Molecular and Integrative Physiology, 241, Art. No.: 110624. https://doi.org/10.1016/j.cbpa.2019.110624 See

The kisspeptin system, a known regulator of reproduction in fish, was investigated during two key phases within the gilthead seabream (Sparus aurata) life cycle: protandrous sex change and larval ontogeny. Seabream specific partial cDNA sequences were identified for two key targets, kissr4 and kiss2, which were subsequently cloned and qPCR assays developed. Thereafter, to examine association in expression with sex change, a group of adult seabream (2+ years old) undergoing sex change were sam...
