The southern scallop (Austrochlamys natans) and the Patagonian scallop (Zygochlamys patagonica) are vital species in the fisheries of Chilean Patagonia. However, overfishing has led to stock depletion, necessitating research for stock restoration and commercial production. This study aimed to evaluate the growth and survival of these scallops in su...
The sub-Antarctic Magellan Ecoregion is a unique biogeographic area located at the southern tip of South America, which has exceptional marine flora and high endemism. Along the coastline, the ochrophytes Macrocystis pyrifera and Lessonia flavicans form vital underwater forests that serve as critical habitats, providing shelter, food and breeding g...
The Antarctic toothfish ( Dissostichus mawsoni ) is the largest notothenioid species in the Southern Ocean, playing a keystone role in the trophic web as a food source for marine mammals and a top predator in deep-sea ecosystems. Most ecological knowledge on this species relies on samples from areas where direct fishing is allowed, whereas in areas...
Bioeconomic and Financial Risks of Commercial Tilapia Cage Culture in Neotropical Reservoir for Aquaculture Investors.
Financial and bioeconomic risks were evaluated for four large commercial Nile tilapia (Oreochromis niloticus) cage projects with production water volume (m 3 ) of 10 to 50 thousand m 3 (Small Volume, SV), 51 to 150 thousand m 3 (Me...
The aim of this study was to analyze the financial and economic risks of tilapia cage culture across different production water volumes (m³). The production water volumes evaluated were 10 to 50 thousand m³ (Small Volume, SV), 51 to 150 thousand m³ (Medium Volume, MV), 151 to 300 thousand m³ (Large Volume, LV), and >301 thousand m³ (Extra-Large Vol...
The sub-Antarctic Magellan Ecoregion is a unique biogeographic area located in the southern end of South America with notable marine flora and high endemism. Brown macroalgae, particularly Macrocystis pyrifera , dominate the coastlines and are considered critical ecosystem engineers, providing shelter, food, and reproduction sites for various speci...
The European aquaculture industry began to undertake Atlantic halibut (Hippoglossus hippoglossus) aquaculture in the 1980s due to the favorable growth rate and high market value of this cold-water marine fish. Atlantic halibut cultivation began in Chile in 1996 in the Magallanes region (53˚S). Chilean aquaculture facilities were finally equipped to...
El estudio de microalgas de diferentes sistemas acuáticos es fundamental para evaluar el potencial biotecnológico que pueden presentar algunos de estos microorganismos, especialmente aquellos capaces de colonizar ambientes extremos en variables como temperatura, pH, salinidad, iluminación, e incluso limitados en nutrientes, ya que estas algas prese...
The main bottleneck for the development of technology for Atlantic halibut culture in Chile, as in the rest of the world, is the supply of juveniles. This the high mortalities of early life stages observed during incubation and larval rearing, seems to be related to a high variability in egg quality, measured in terms of quantity, quality and brood...
The Patagonian toothfish Dissostichus eleginoides is one of the most important fisheries from the Southern Ocean. The biology of this species is relatively well studied and some nutritionals issues have also been reported; however there is no information about the composition of the bacterial community of the gastrointestinal tract, which is essent...
The Patagonian toothfish or Chilean sea bass (Dissostichus eleginoides), found in the Southern Ocean surrounding Antarctica, is an important fishery species for Chile. This high-value species is regarded as overfished, making it an attractive target for aquaculture. When developing a reproduction program for any aquaculture species, it is important...
Invasive species have become widespread in aquatic environments throughout the world, yet there are few studies that have examined genomic variation of multiple introduced species in newly colonized environments. In this study we contrast genomic variation in two salmonid species (anadromous Chinook Salmon, Oncorhynchus tshawytscha, 11,579 SNPs and...
Los peces marinos de aguas frías se han convertido en una importante fuente alimenticia para el consumo humano, principalmente porque poseen altos contenidos de ácidos grasos de cadena larga, omega 3 y 6, reconocidos como saludables para los seres humanos. Esto ha provocado una fuerte demanda y presión de pesca, que para el caso del bacalao de prof...

Historically in Chile the aquaculture has been salmon and mussel farming, but the Chilean government, encouraged the diversification of aquaculture through the introduction of several flatfish such as Turbot (Psetta maxima), Hirame (Paralichthys olivaceus) and Atlantic Halibut (Hippoglossus hippoglossus), the latter was introduced in the Chilean Pa...
One of the main problems facing Atlantic halibut hatcheries is the high mortality in the early stages of larval development. Several factors could be involved, for example: water quality, diseases or abnormalities, such as deformities occurring in the yolk sac larvae prior to exogenous feeding. The aim of this study was to identify differences in b...

Increased atmospheric CO2 emissions are inducing changes in seawater carbon chemistry, lowering its pH, decreasing carbonate ion availability and reducing calcium carbonate saturation state. This phenomenon, known as ocean acidification, is happening at a faster rate in cold regions, i.e., polar and sub-polar waters. The larval development of Arbac...
