An adequate daily intake of minerals is essential for the prevention of chronic nutrition-related and degenerative diseases, including cancer, cardiovascular disease, and obesity. Seaweeds are marine aquatic vegetable that are rich in nutrients. They also have a natural and sustainable origin and clean and renewable sources when they come from mari...

Omega-3 long-chain polyunsaturated fatty acids (n-3 LC PUFAs) and vitamin D3 are essential components of human nutrition. A regular human diet is highly deficient in n-3 LC PUFAs. Fish like salmon are highly recommended in the human diet as they are a major source of high-value n-3 LC PUFAs and vitamin D3. The levels of these nutrients have been de...

Pharmacotherapy has long been used to control viral diseases. However, its success is questionable because its use can negatively impact environmental and human health. An alternative solution is the use of functional foods and diets containing natural products, which tend to be more biodegradable than synthetic molecules and are less likely to gen...

Aquaculture in Chile has been practiced since the 1920s; however, it was not until the 1990s that aquaculture became an important sector here. Important species in Chilean aquaculture include salmonids, algae, mollusks, and turbot. Salmonids are the dominant species in Chilean aquaculture for both harvest volume and export value, their production r...

Red macroalgae (Phylum Rhodophyta) are considered to be an important source of biologically active metabolites; their use as functional feed ingredients in fish diets can increase disease resistance and animal growth. Furthermore, red macroalgae can be cultured in a sustainable and environmentally friendly manner. We evaluate the potential antivira...

Sustainably farmed Atlantic salmon could drive global food system solutions by contributing essential nutrients to the human diet while delivering high-quality protein. One of the biggest obstacles to sustainable salmon aquaculture in Chile is the prevalence of piscirickettsiosis disease caused by the Gram-negative bacteria Piscirickettsia salmonis...

The parr-smolt transformation in salmonids involves a critical period characterized by systemic changes associated with the fish's immune response. In this context, as a dietary ingredient in functional diets, microalgae offer an alternative due to their nutritional and bioactive compounds that could strengthen the immune status. This study evaluat...

The exponential growth of aquaculture over the past 30 years has been accompanied by a parallel increase in the use of antimicrobials. This widespread use has had negative effects on animal, human and environmental health and affected the biodiversity of the environments where aquaculture takes place. Results showing these harmful effects have been...

Sustainability in aquaculture is a necessity of the future, not only as the most promising means of supplying the protein that the world will require to feed its growing population but to offer needed conservation of the world’s ocean resources. The use of wild fish inputs in farm-raised fish outputs has been a primary concern of sustainability in...

Aquaculture is seen as an ambition for food security and nutrition. Fish such as salmonids are a primary source of protein and essential nutrients. They provide income for communities across the world and have a smaller carbon footprint than other terrestrial animal-production systems. However, in terms of production, fish diseases are a constant t...

La sustentabilidad en la acuicultura es una necesidad del futuro, no solo como el medio más prometedor de suministrar la proteína que el mundo necesitará para alimentar a su creciente población, sino también para ofrecer la conservación necesaria de los recursos oceánicos. El uso de insumos de peces silvestres en la producción de peces criados en g...

La contaminación por micotoxinas afecta la producción mundial de cultivos. La micotoxicosis en la acuicultura ha aumentado con el reemplazo de las materias primas de origen vegetal. La calidad de los productos usados para la acuicultura es un factor limitante debido a que estos alimentos son sustratos de crecimiento de hongos, que favorecen la sínt...

Caligus rogercresseyi commonly called sea louse is an endemic copepod ectoparasite, which parasites farmed Salmo salar. This parasitism generates great economic losses, predisposition to secondary infections and welfare issues. Understanding the biology behind the mechanisms involved in the immune response of the host is important for selecting ind...

Abstract Currently, Caligus rogercresseyi represents a big challenge for the Chilean salmon farming industry. Diverse efforts have been applied to control and prevent the infestation of Salmo salar with this parasite including different studies and preventive public health policies, however the results have not being satisfactory. Our study aims to...

Functional diets that include bioactive ingredients have been shown to increase disease resistance and growth in fish. Among the dietary options is the use of seaweed, which offers both essential nutrients and biologically active metabolites. In a study, Atlantic salmon fed diets with red seaweed had significantly higher levels of anti- viral activ...

Haliotis sp. is a very expensive delicatessen food product, usually given as a high quality present in the Asiatic culture. The price of this commercially valuable shellfish is directly related with the quality in terms of size, texture, color, flavor and appearance. Natural and artificial diet, post-harvest handling and process are the main import...
