“…Chemical inactivation is the process of rendering pathogenic bacteria dormant by destroying their nucleic acids or proteins with chemical chemicals. Physical inactivation is complex, costly, limiting and unstable, while in contrast, chemical inactivation is simple, low cost and reliable, and is the most commonly used method of inactivation ( 124 , 125 ). In 1942, Duff first applied an inactivated vaccine against A. salmonicida on trout to give them immune protection, which became a precedent for fish vaccine application.…”

Diseases are a significant impediment to aquaculture’s sustainable and healthy growth. The aquaculture industry is suffering significant financial losses as a result of the worsening water quality and increasing frequency of aquatic disease outbreaks caused by the expansion of aquaculture. Drug control, immunoprophylaxis, ecologically integrated control, etc. are the principal control strategies for fish infections. For a long time, the prevention and control of aquatic diseases have mainly relied on the use of various antibiotics and chemical drugs. However, long-term use of chemical inputs not only increases pathogenic bacteria resistance but also damages the fish and aquaculture environments, resulting in drug residues in aquatic products, severely impeding the development of the aquaculture industry. The development and use of aquatic vaccines are the safest and most effective ways to prevent aquatic animal diseases and preserve the health and sustainability of aquaculture. To give references for the development and implementation of aquatic vaccines, this study reviews the development history, types, inoculation techniques, mechanisms of action, development prospects, and challenges encountered with aquatic vaccines.

“…Recent biotechnological research has aided in the clarification and control of the pathogenic processes in fish, aiming to diagnose the main diseases, identify virulence factors, characterize isolated and develop vaccines. Although many pathogens already have specific vaccines, such as Streptococcus iniae (Klesius et al, 2000;Locke et al, 2008;Jeong et al, 2016), and Aeromonas salmonicida (Tatner, 1987), there are still several important diseases, mainly of viral and parasitic origin, for which there is no prophylactic treatment (Heppell & Davis, 2000;Ringø et al, 2014).…”

Opportunities and challenges for fish culture in Brazilian reservoirs: a review

2018

Aim Aquaculture plays an important role in the world and in Brazil. Artificial construction of water bodies, such as ponds and reservoirs, has allowed for fish culture in cages in those environments, generating conflicts over the use of these public waters. The producers are seeking to increase production, and the ecosystem is susceptible to the impacts caused by production activity. The aim of this review was to identify questions about these conflicts (productivity × environment) and to indicate possible solutions to the main problems related to fish farming in reservoirs. Methods A bibliographical survey was carried out on the main aspects of cage fish farming in Brazilian reservoirs. Studies from 1977 to 2018 (scientific journals, books, and thesis) were revised using seven databases, the CAPES periodicals portal and Google Scholar websites. The main keywords used were “aquaculture”, “reservoir”, “cage”, “eutrophication”, “carrying capacity”, “impacts”, “oligotrophic”, “escapes”, “hybrids”, and “pollution”. Results We accessed approximately 330 and cited 151 documents. Conclusions The negative aspects associated with cage fish farming, as escapes of cultivated fish, and the possible solutions of this and others negative impacts were addressed, identifying mechanisms for reducing conflicts between environmental impacts and aquaculture production. Potential solutions include the use of native fish species or sterile species, implementation of monitoring systems of the surrounding area, adoption of measures to reduce the accidental escape of fish, use of multitrophic culture systems, use of highly digestible diets with appropriate food management, and use of computer programs that incorporate current and historical environmental data to calculate carrying capacity and choose the most appropriate location for production.

“…A variety of interdisciplinary studies entailing selective breeding for improvement of growth [4,5], feed [6][7][8], and vaccine development [9][10][11][12][13] have been carried out to develop flounder as a national strategic breed. The government has been promoting the use of formulated feeds since 2004 in order to develop a sustainable aquaculture industry.…”

The objective of this study was to conduct field experiments comparing formulated (extruded pellets (E.P)) and raw-fish (moist pellets (M.P)) feeds at two flounder aquaculture farms for six months to obtain the basic data necessary for improving aquafarmers’ awareness of feed-quality issues and firmly establish and expand the use of formulated feed. According to the results, the M.P group was higher in weight gain, feed efficiency ratio, protein efficiency ratio, and specific growth rate and lower in mortality rate than the E.P group. All cases of mortality were caused by six kinds of disease, four of which (Vibrio sp., Edwardsiella sp., Streptococcus sp., and Scuticociliates) were common to the two groups, whereas Lymphocystis arose only in the M.P group and abdominal inflation only in the E.P group at both farms. As for mortality in the present experiment, the numbers were 1047 at Da-Hae farm and 1167 at Global farm, with more fish dying in the E.P tanks than in the M.P tanks. By multiplying the number of deaths by selling price, the economic losses were $9650 and $10,756, respectively. Therefore, it should be considered an urgent priority to develop flounder-exclusive formulated feed for improved digestion and absorption rate and also to establish a water-quality-improvement management plan.
