Is the Plant Bolboschoenus maritimus an Adequate Biomonitor for Trace Metal Con...

Santos, Márcia S. S.; Pedro, Carmen A.; Ferreira, Susana M. F.; Gonçalves, Sílvia C.

Monitoring the negative impacts of trace metals is crucial to assess the health and stability of ecosystems. In salt marshes, halophyte plants were reported as possible bioaccumulators of these elements. The aim of this work was to explore the bioaccumulation potential of Bolboschoenus maritimus as a tool for monitoring the presence of metals in coastal environments. Bolboschoenus maritimus were collected from ...

Principais Patógenos que Afetam Peixes Cultivados em Portugal

Pires, Damiana; Vaz, Mariana; Pires, Pedro; Passos, Ricardo; Carmo, Beatriz; Santos, Paulo; Tomás, Mafalda; Ferreira, Susana M. F.; Baptista, Teresa

A mortalidade de peixes que ocorre nas explorações aquícolas, devida à ação de agentes patogénicos, constitui ainda um dos maiores entraves ao desenvolvimento económico do sector. Tendo em conta a sua origem, as doenças podem subdividir-se em não infeciosas e infeciosas, sendo estas últimas as de maior importância e a principal causa de perdas económicas elevadas. As doenças infeciosas agrupam-se em três catego...

Somatic growth and gonadal development of Paracentrotus lividus (Lamarck, 1816)...

Lourenço, Sílvia; Cunha, Beatriz; Raposo, Andreia; Neves, Marta; Santos, Pedro M.; Gomes, Ana S.; Tecelão, Carla; Ferreira, Susana M. F.

Sea urchins’ gonads are a delicacy highly appreciated worldwide. In Europe, Paracentrotus lividus is one of the most valuable edible sea urchin species and a desired target for aquaculture. One of the challenges of echinoculture is to increase the sea urchins’ growth rate during the on-growing phase and reducing the production cycle required to obtain sea urchins of commercial size (test diameter ≈ 50 mm). The ...

Effects of single and mixed-diatom diets on growth, condition, and survival of ...

Gomes, Ana; Lourenço, Sílvia; Santos, Pedro M.; Raposo, Andreia; Mendes, Susana; Gonçalves, Sílvia C.; Ferreira, Susana M. F.; Pombo, Ana

The development of rearing protocols promoting the larval development, pre and postmetamorphosis are key for echinoculture. Mixed diets combining diatom with other microalgae have been used with success and Rhodomonas sp. (Rho)-based diets showed promising results in larval survival. This study was aimed to evaluate the rearing success of Paracentrotus lividus larvae fed with mixed diets combining Rho with two ...

The effect of temperature on somatic and gonadal development of the sea urchin ...

Santos, Pedro M.; Albano, Pedro; Raposo, Andreia; Ferreira, Susana M. F.; Costa, José L.; Pombo, Ana

The common sea urchin Paracentrotus lividus (Lamarck, 1816) is the most consumed echinoid in Europe. It is considered a seafood delicacy, given its high-valued gonads. In sea urchins, temperature probably represents the most important abiotic factor affecting several physiological processes and it is essential to better establish optimal reference conditions for aquaculture. In this study, four rearing temperat...

Insight into aquaculture’s potential of marine annelid worms and ecological con...

Pombo, Ana; Baptista, Teresa; Granada, Luana; Ferreira, Susana M. F.; Gonçalves, Sílvia C.; Anjos, Catarina; Sá, Erica; Chainho, Paula

Polychaetes are marine annelid worms that can contribute to aquaculture diversification. Its culture has been viable, and commercially attempted, but intensive production has progressed only in few countries around the world. In the countries with no production, marine polychaetes are imported or harvested. A strong and sustained research investment provided to a better understanding of the nutritional requirem...

Optimization of feeding quantity and frequency to rear the cyprinid fish Garra ...

Catarino, Mafalda M. R. S.; Gomes, Mónica R. S.; Ferreira, Susana M. F.; Gonçalves, Sílvia C.

Garra rufa has a high commercial value, but their rearing methods are still unknown. Aspects like an adequate daily dose and feeding frequency need to be investigated. This work aimed to establish the optimal feed dose per day to obtain satiation and the optimal frequency of feeding to rear a specific size class of G. rufa. A total of 60 fish were distributed by six aquaria containing 10 fish. First, the fish w...

Can artificial diets be a feasible alternative for the gonadal growth and matur...

Santos, Pedro M.; Ferreira, Susana M. F.; Albano, Pedro; Raposo, Andreia; Costa, José L.; Pombo, Ana

Paracentrotus lividus (Lamarck 1816) has high-value reddishorange gonads that are regarded as a delicacy. In this study, three jellified diets have been tested for 90 days to assess the effect of different diets on P. lividus somatic and gonadal growth, gonad color, and reproductive state. All diets contained agar as a gelling agent and consisted of: maize and spinach (A); maize, spinach, and macroalga Laminari...

Homegreens - Aquaponics System as an Educational Tool towards a Sustainable Future

Carreira, Rute; Diz, Francisco; Pessanha, Luis; Bernardino, Raul; Franco, Inês M.; Mota, Alexandra; Faustino, Emanuel; Silva, Orlando R.

Aquaponics is an integrated production practice that emerges from the combi-nation of two farming techniques: hydroponics and aquaculture. It consists in a simulation of a natural ecosystem that grows plants without soil substrate in the nutrient enriched waters recirculated from aquaculture systems. This type of production offers several advantages, namely economic and ecological ones. Homegreens is a project ...
