Epidemiology of Salmonid Rickettsial Septicemia (SRS) in Farmed Salmon: The Role of Sea Lice Infestations in Mortality Risk. [PDF]

J Fish Dis
ABSTRACT Piscirickettsia salmonis, the causal agent of salmonid rickettsial septicemia (SRS), is the main pathogen affecting farmed salmonids in Chile. Outbreaks of SRS lead to substantial economic losses for producers. Many determinants related to SRS outcomes are still poorly understood.

Opportunistic Feeding and Parasite Assemblages in Sei Whales (<i>Balaenoptera borealis</i>) From Southern Chile Revealed by DNA Metabarcoding. [PDF]

Ecol Evol
This study represents the first metabarcoding‐based description of prey composition and parasite‐associated taxa in stranded sei whales from southern South America. ABSTRACT Balaenopterid whales are major consumers in pelagic ecosystems and play a fundamental role in marine food webs.

Temperature and Ultraviolet Radiation Influence the Skin Microbiome of Humpback Whales. [PDF]

Mol Ecol
ABSTRACT The skin microbiome of humpback whales harbours diverse microbial communities that play a crucial role in host skin protection and environmental interaction. However, studies on cetacean skin microbiomes in the Southern Hemisphere focus on feeding grounds, with limited information on microbiome dynamics at breeding grounds and during migration

El biofloc en la acuicultura

Revista Centro Azúcar, 2021
Con una población creciente en la Tierra, la demanda de alimentos acuáticos sigue aumentando y, por lo tanto, se requiere la expansión e intensificación de la producción acuícola. El interés en los sistemas basados en biofloc ha aumentado en los últimos veinte años porque estos sistemas pueden proporcionar bioseguridad, son financieramente sostenibles ...

Cryptobenthic reef fishes may not be safe from invasive lionfish (Pterois spp. Oken, 1817). [PDF]

J Fish Biol
Abstract Lionfish (Pterois spp.) are hypothesized to negatively influence cryptobenthic reef fish assemblages through predation. We evaluated these potential effects on Caribbean reefs in Costa Rica and tropical reefs in Brazil. Brazil provided a reference condition for cryptobenthic assemblages prior to lionfish invasion, while the Costa Rica sites ...

Admixture and Selection Driven by El Niño-Southern Oscillation Events Shape the Genetic Structure of <i>Octopus mimus</i>-<i>O. hubbsorum</i> Complex Across the Humboldt and South Equatorial Current Transition Zone. [PDF]

Ecol Evol
Whole‐genome sequencing of the Octopus mimus–O. hubbsorum complex in the eastern Pacific identified two main genetic clades—northern warm‐water and southern cold‐water lineages—with a broad admixture zone during ENSO years where admixed individuals reflect both their genomic makeup and local environments.

Marine Heatwaves Overwhelm the Buffering Benefits of Marine Protected Areas: Two Decades of Collapse in a Mediterranean Gorgonian. [PDF]

Glob Chang Biol
Two decades of monitoring across the north‐western Mediterranean reveal a 45% regional biomass loss of the foundation gorgonian Paramuricea clavata, driven by increasingly frequent marine heatwaves. Protection sustained higher biomass but could not halt decline, underscoring the urgent need to pair conservation with climate action to preserve red ...

Purification of luteinizing hormone (LH) in the sea bass (Dicentrarchus labrax) and development of a specific immunoassay

Ciencias Marinas, 2006
 The luteinizing hormone (LH) is a key regulator of the processes of gonad maturation, ovulation/spermiation and spawning in vertebrates. The present study describes the purification of LH from pituitaries of a teleost fish, the European sea bass ...
