“…In the current study, Proteobacteria (>85% of the analysed sequences) and Firmicutes (5%–12%) were the most abundant phyla in the autochthonous intestinal microbiota of gilthead seabream. These results were in agreement to those reported by different authors in the same species (Cordero et al, ; Estruch et al, ; Piazzon et al, ), as well as in other temperate marine fish species (Cardá‐Dieguez, Mira & Fouz, ; Tapia‐Paniagua et al, ) and salmonids (Dehler, Secombes, & Martin, ; Merrifield, Burnard, Bradley, Davies, & Baker, ). In our study, this phylum never represented more than 1.5% of the sequences analysed, whereas other 22 phyla were found, but these were <1% of the total sequences.…”

The effect of spray‐dried porcine plasma (SDPP) on the intestinal histological organization and autochthonous microbiota composition was evaluated in Sparus aurata. Fish were fed a basal diet (51 g/kg protein, 17 g/kg fat, 20.6 MJ/kg gross energy) and a diet containing 3 g/kg SDPP for 95 days (initial body weight, BW = 9.5 ± 0.2g, mean ± SD). The inclusion of SDPP promoted growth (p < .05), being fish fed the SDPP diet 6.2% (BW = 88.2 ± 1.6 g) heavier than the control (BW = 82.7 ± 3.2 g). SDPP increased the density of intestinal goblet cells (p < .05), whereas no differences in villi height were found (p > .05) between both groups. Intestinal microbiota was dominated by Proteobacteria (>85%) and Firmicutes (5%–12%), whereas Bacteroidetes never represented more than 1.5%. γ‐Proteobacteria, and Bacilli and Clostridia were the predominant classes. The short administration of SDPP (20 days) resulted in changes in microbiota diversity and richness associated with an increase in the sequences of the genus Lactobacillus and to a decrease in the genus Vibrio, whereas these changes were reverted at 95 days. Intestinal goblet cell density was not correlated to microbiota diversity and richness changes rather than to the immunostimulatory effect of the SDPP.

“…However, a downregulation in IgM has also been reported recently in seabream fed with probiotics (Guzmán-Villanueva et al, 2014). Interestingly, a posterior study, also in Sparus aurata and using the same probiotic encapsulated with alginate, revealed an increase in IgM (Cordero et al, 2015). As mentioned previously, the importance of the dose given to the animal is reflected in these results; the protective effect of the probiotic lead to an increased response, probably due to the increase in the number of bacteria delivered safely to the intestine through encapsulation.…”

Mucosal surfaces are the main route of entry for pathogens in all living organisms. In the case of teleost fish, mucosal surfaces cover the vast majority of the animal. As these surfaces are in constant contact with the environment, fish are perpetually exposed to a vast number of pathogens. Despite the potential prevalence and variety of pathogens, mucosal surfaces are primarily populated by commensal non-pathogenic bacteria. Indeed, a fine balance between these two populations of microorganisms is crucial for animal survival. This equilibrium, controlled by the mucosal immune system, maintains homeostasis at mucosal tissues. Teleost fish possess a diffuse mucosa-associated immune system in the intestine, with B cells being one of the main responders. Immunoglobulins produced by these lymphocytes are a critical line of defense against pathogens and also prevent the entrance of commensal bacteria into the epithelium. In this review we will summarize recent literature regarding the role of B-lymphocytes and immunoglobulins in gut immunity in teleost fish, with specific focus on immunoglobulin isotypes and the microorganisms, pathogenic and non-pathogenic that interact with the immune system.

“…Marine fish larviculture has proven challenging, with high mortalities due to many complex and unknown causes; however, since the specific immune system is not completely mature during the early weeks after hatching, microorganisms may be an important cause of epizootic mortality [89][90][91]. Probiotic administration through incubation water can improve and stimulate the non-specific defense, as the epidermal mucus layer comprises the primary interface between larvae and the aquatic environment [29]. A significantly higher larval survival rate following the addition of the probiotic bacterium L. plantarum to the incubation water of Atlantic halibut (Hippoglossus hippoglossus L.) eggs and larvae was confirmed [91].…”

Over the last few decades, the contribution of aquaculture to animal protein production has increased enormously, and the sector now provides almost half of the fish and shellfish consumed worldwide, making it a major food producer. Nevertheless, many factors, including infections, pollution, and stress, may result in significant economic losses. The aquaculture industry will not be totally successful without the therapeutic and preventive means to control all these factors. Antibiotics (long used in aquaculture practice) have tended to aggravate the problem by increasing antibiotic resistance. Concomitantly, probiotics have widely been suggested as eco-friendly alternatives to antibiotics. However, the way in which probiotics are applied in aquaculture is a key factor in their favorable performance. The aim of this review was to examine the current state of probiotics administration through the water in finfish aquaculture. The review also attempts to cover the research gaps existing in our knowledge of this administration mode, and to suggest the issues that need to be investigated in greater depth.
