A craca gigante dos Açores (Megabalanus azoricus) é uma espécie com elevado valor comercial no arquipélago, cujo potencial para produção em aquacultura tem sido avaliado nos últimos anos. Neste âmbito, o Aqualab realizou diversas experiências laboratoriais que levaram à definição de protocolos de cultivo larvar desde a sua postura até ao assentamen...
Article
Megabalanus azoricus giant barnacles are the most traditional seafood of the Azores archipelago (NE Atlantic). This valuable commercial species has been highly exploited in the past and it is considered one of the key species for the development of aquaculture in the region. Despite the importance for conservation and aquaculture there is still a l...

The production of cultured limpets is a recent research field contributing to aquaculture diversification, focusing on low trophic species while reducing the carbon footprint. Limpets are gastropods that colonize rocky substrates and are mostly present on tidal and subtidal shores. This animal group is in high commercial demand and is endangered in...

The limpet Patella aspera is an endemic species to the Macaronesian Islands. Its high economic value and vulnerability to exploitation has triggered the interest in the development of its aquaculture. Significant progress has been made in recent years, with the establishment of artificial fertilization and larval production protocols. However, ther...

Temperature shock induced spawning might increase reproduction performance in European abalone BACKGROUND: There are three main spawning induction methods used for abalone species: Thermal shock (Temp.), hydrogen peroxide (H2O2) and UV irradiation (UV). The aim of this study is to evaluate if there is any influence of the spawning method in the rep...

P. candei has great economic value in the Macaronesia region. The interest on developing a sustainable aquaculture production of this resource has grown in recent years, due to high demand and sensitivity to exploitation (Hawkins et al., 2000). Therefore, this study is focused on the performance of two different methods of obtaining P. candei larva...

This report describes the research work carried out at AquaLab between 2018 and 2019. The results presented here refer to the domestication process of Haliotis tuberculata coccinea, the optimization of production protocols for Ulva sp. and preliminary studies on the cultivation of sea cucumbers (Holoturia sp.). The first result of interest is the s...

Control over the production cycle of the animals is essential in order to be able to control and manage all stages of the life cycle of each species in captivity. This process is called domestication. In aquaculture, domestication is a process that, on a five-level scale, begins with simple feeding and growing of a wild species until complete manag...

The contribution of aquaculture to worldwide seafood production has seen a steady increase over the past decades, becoming a significant economic activity for many nations. In the Autonomous Region of the Azores characterised, as other outermost regions, by their remoteness, insularity, small size, difficult topography and climate, economic depende...

We assessed the dietary value of available seaweeds (Ulva lactuca, Ulva intestinalis and Sargassum vulgare) as food for juvenile abalone Haliotis tuberculata coccinea. During the 6 weeks that the experiment lasted, initial shell length and weight increased from 13.95 ± 0.32 mm to 15.30 ± 0.30 mm and from 0.39 ± 0.02 g to 0.47 ± 0.03 g. Ulva lactuca...

This report presents the work done and the preliminary results obtained during a demersal survey cruise that took place on board the R/V “Arquipélago” of the University of the Azores during the Spring/Summer of 2016 (between April 27th and July 16th). This cruise was intended to estimate relative abundance of demersal species in the Azores. A total...

A series of experiments were conducted to obtain an efficient larval rearing protocol for Megabalanus azoricus. The first part of this study investigates the effect of microalgae-based diets on survival and larval development. Mono and mixed-diets were tested at 20 AE 1°C, in a sequence of 11-day feeding experiments. The second part presents a prel...

Nine microsatellite loci were isolated and characterized in Megabalanus azoricus. Forty specimens from two sampling sites in Faial Island (Azores) were successfully genotyped and tested loci showed to be polymorphic. The total number of alleles sampled range from 6 to 12 and the overall allelic richness varied from 4.69 to 10.38. While the presence...

Aquaculture is an emergent industry which already supplies almost half of the seafood eaten worldwide (FAO 2010). Besides being a critical sector of food production, it can also be a necessary component of recreational and commercial fisheries and an efficient management tool for conservation programs (Diana 2009). Although aquaculture in the Azore...

In this study we examined the effect of: observer presence; observer speed; and the impact that multiple surveys had on the number of counted fish in a visual census survey in a typical Mediterranean rocky habitat. SCUBA observer presence had no influence on the number of fish per survey. An improvement in the methodology to estimate the number of...

We examined the social organization and reproductive pattern of a population of Sparisoma cretense L. at Lampedusa Island (Italy). During the breeding season (July to September) individuals occur either in territorial or in non-territorial groups, which quantitatively differ with respect to use of space, sex-ratio and sexual activity. Territorial g...
