First estimates of metabolic rate in Atlantic bluefin tuna larvae.
2020
Atlantic bluefin tuna is an iconic scombrid species with a high commercial and ecological value. Despite their importance, many physiological aspects, especially during the larval stages, are still unknown. Metabolic rates are one of the understudied aspects in scombrid larvae, likely due to challenges associated to larval handling before and during respirometry trials. Gaining reliable estimates of metabolic rates is essential to understand how larvae balance their high growth needs and activity and other physiological functions, which can be very useful for fisheries ecology and aquaculture. This is the first study to (a) estimate the relationship between routine metabolic rate (RMR) and …

Immune-Endocrine Interactions in the Fish Gonad during Infection: An Open Door to Vertical Transmission
2018
The interaction between the immune and endocrine systems has long been recognized in vertebrates. In fish, it is known that the prevalence and intensity of such infections are higher in males than in females and probably related to sex steroid hormone levels. In addition, the immune response in the fish gonad tissues is specifically regulated to prevent infertility. This condition is used by some pathogens to colonize the fish gonad, evade the systemic immune response, and so spread to the progeny. This review brings up to date our knowledge concerning fish gonad immunity and its regulation, immune-endocrine interactions, and how some pathogens use this tissue to spread to the progeny throu…

Effects of the gill parasite Zeuxapta seriolae (Monogenea: Heteraxinidae) on the amberjack Seriola dumerili Risso (Teleostei: Carangidae)
2004
Zeuxapta seriolae (Monogenea: Heteraxinidae) infection was associated with important mortalities of amberjacks (Seriola dumerili) reared in tanks in the experimental facilities of the Spanish Institute of Oceanography (Western Mediterranean) during the period 1998–2000. Fish infested by this parasite presented characteristics similar to those described for Seriola quinqueradiata parasitized by Heteraxine heterocerca in Japan. All dead amberjacks had high parasite abundance (mean abundance±S.D.=686.7±125.4) and egg strings entangled in gills. The parasitological analysis of 17 live amberjacks collected from the infested tanks showed that 41.2% of fish harboured Z. seriolae with intensities r…
Metazoan parasites in meagre and gilthead seabream aquaculture: monogeneans, from biology to infection management
2021
Pathologies represent a relevant bottleneck for aquaculture development and must be taken into account in the selection of potential species for diversification. Determining pathogens affecting new and traditional cultured species as well as their potential impacts on fish health becomes essential for optimising the development and viability of fish productions. Among pathogens, monoxenous metazoans, such as platyhelminth monogeneans, have a marked influence on fish health, especially in aquaculture where they cause significant economic losses in the main fish-farming industries. Population dynamics in host-parasite systems are modulated by environmental conditions. Therefore, effective man…
Desarrollo de un modelo matemático para la evaluación del proceso de crecimiento y engorde en los cultivos comerciales de dorada (Sparus aurata)
2012
En las últimas décadas la acuicultura se ha desarrollado más que la mayoría de las tecnologías agroalimentarias y se ha mostrado como un instrumento capaz de aumentar la cantidad de proteína animal de alta calidad en todos los países en especial en los que están en vías de desarrollo. En el área mediterránea la piscicultura marina se ha dirigido a especies de elevado valor comercial y al que se le puede obtener un valor añadido en aras de la calidad. Especies como la dorada o la lubina, ya no se presentan en los mercados como fruto de las pesquerías sino mayoritariamente como productos de la acuicultura, lo que ha permitido su presencia en los mercados independientemente de la época del año…
