Special Issue Information

Dear Colleagues,

The increase in global aquaculture production is having a negative impact on the environment. These negative effects include dependence on the use of fishmeal and fish oil to feed carnivorous species, pollution of the aquatic environment with wastewater effluents, and the use of antibiotics for the treatment of infectious diseases, which affects the environmental microbiota and generates resistant pathogens that can cause public health risks.

As a solution to these effects, there is the possibility of using probiotic microorganisms. These microorganisms can positively affect aquaculture in several ways: they facilitate feed digestibility and provide essential nutrients that can reduce the need for fishmeal and fish oil; they can break down organic debris, thus enabling effluent purification; and their activity as immunostimulants and pathogen antagonists reduces the need for antibiotics and other chemotherapeutics.

Thus, the aim of this Special Issue is to expand knowledge on the wide range of applications of probiotics to improve sustainability in aquaculture.

Effect of the Potential Probiotic Vibrio proteolyticus DCF12.2 on the Immune System of Solea senegalensis and Protection against Photobacterium damselae subsp. piscicida and Vibrio harveyi

Abstract

Some of the characteristics of probiotics used in aquaculture are the antagonistic activity against pathogens and the activation of the immune response. Moreover, some probiotics with common antigens to pathogens can produce antibodies that react with these pathogens. One of those potential probiotics is Vibrio proteolyticus DCF12.2, a strain with the capacity to produce antibodies in soles (Solea senegalensis) that react with Photobacterium damselae subsp. piscicida and Vibrio harveyi antigens. Therefore, the objective of the work was to determine the capacity of DCF12.2 to activate the immune response in the sole, providing protection against both pathogens. For this purpose, DCF12.2 was administered to cultured soles by intraperitoneal injection, bath, and diet. The DCF12.2 strain activated the gene expression related to the fish immune response and increased the antibody production with cross-reaction to P. damselae subsp. piscicida and V. harveyi cells. Challenges with P. damselae subsp. piscicida resulted in a 30–40% relative percent survival (RPS) through DCF12.2 treatments. After challenge with V. harveyi, only intraperitoneal treatment protected the fish (67% RPS). In conclusion, the DCF12.2 strain showed great potential to be used to prevent diseases caused by both pathogens, and indicates a way to use probiotics as live vaccines. Full article

Effect of Bacillus Probiotics on the Immunological Responses of Nile Tilapia (Oreochromis niloticus): A Review

by Vicent Michael Shija, Kwaku Amoah and Jia Cai

Abstract

The use of antibiotics and therapeutics for Nile tilapia has increased along with its increased production and intensification. Probiotics have been studied as an alternative to the excessive use of antibiotics in fish diets. Studies have demonstrated that dietary Bacillus probiotic inclusion promotes faster growth and disease resistance in farmed fish species. Despite advances in research, there is still uncertainty about the mechanisms controlling the immune response of fish. In this review, we summarize and discuss recent research on the immune responses of Nile tilapia to Bacillus probiotics. Through the use of immunological information including phagocytosis, lysozyme activity, respiratory activity, antioxidant proteins, complement activity, and immune-related gene expression, researchers hope to develop effective strategies for successfully using Bacillus probiotics in Oreochromis niloticus farming.
