Strategy of bioremediation in recirculating aquaculture systems using constructed microbial mats
(Journal of Chemical, Biological and Physical Sciences, 2014-11-30)
Due to strict international standards, every day there is greater interest in developing environmentally sound treatment systems in aquaculture facilities that can remove contaminants from effluent and allows for the reuse ...
Determinación del flujo de agua para la biorremediación en sistemas acuícolas recirculados utilizando tapetes microbianos construidos
(2015-09-01)
La cantidad de agua necesaria en los sistemas de producción aumenta con la Intensificación; se han establecido tasas económicas de uso. Esta situación ha obligado a los productores a diseñar sistemas que les permitan seguir ...
Spotted rose snapper (Lutjanus guttatus) aquaculture research and development as socio-economic alternative for Costa Rican fishing communities
(2010-06-01)
The spotted rose snapper (Lutjanus guttatus) is one of the main target coastal species, but landings are decreasing in quantity and size. Reports include a mean capture size of 50 cm with gill nets and 38 cm with bottom ...
Isolation and characterization of partial insulin-like androgenic gland hormone gene from distal terminal ampoules of three marine shrimp Penaeus species from the Eastern Pacific
(2018)
The expansion of the shrimp industry depends on scientific advances related to the understanding of reproductive endocrinology that allows the development of aquaculture programs based on biotechnology. An insulin ...

(Universidad Nacional (Costa Rica), 2019-01)
Se definieron las dosis más eficientes de aceite de eugenol Syzygium aromaticum para la sedación quirúrgica en juveniles de pargo manchado (Lutjanus guttatus) y se determinó el tiempo mínimo de exposición de no retorno, ...
Growth and fillet yield in recirculation systems of Lobotes pacificus (Perciformes: Lobotidae), a species with aquaculture potential
(Universidad Nacional (Costa Rica), 2019-07)
The genus Lobotes extends across tropical and subtropical areas of oceans such as the Atlantic and the Pacific; it is extracted in artisanal fisheries, and its aquaculture production technology is still under investigation. ...
Crecimiento de juveniles de la corvina aguada, Cynoscion squamipinnis (Perciformes: Sciaenidae) en cautiverio
(Universidad Nacional (Costa Rica), 2016-07-31)
Peces juveniles de corvina aguada, Cynoscion squamipinnis, obtenidos a partir de desoves espontáneos en cautiverio fueron engordados por 355 días en la Estación de Biología Marina Juan Bertoglia Richards ...
Determinación del flujo de agua para la biorremediación en sistemas recirculados acuaculturales utilizando tapetes microbianos construidos
(2015)
The effect of water flow rate was evaluated on the microbial mats efficiency to remove total ammonia nitrogen (TAN, NH4+-N+ NH3-N), nitrite (N-NO2-), nitrate (N-NO3-) and orthophosphate (P-PO4-3) in a pilot recirculation ...
Evaluation of Escherichia coli concentrations in Crassostrea gigas and seawater in two oyster growing areas in the Gulf of Nicoya, Costa Rica
(Universidad Nacional (Costa Rica), 2014-12)
Costa Rica does not have references on the health quality of Crassostrea gigas growing areas, which can pose a po tential public health risk. This study evaluated the temporal trends of Escherichia coli concentrations in ...
