Aquaculture is the fastest growing animal food production industry, now producing 50% of all fish. However, aquaculture feeds remain dependent on fishmeal derived from capture fisheries, which must be reduced for continued sustainable growth. Purple phototrophic bacteria (PPB) efficiently yield biomass wastewater with high product homogeneity, a relatively protein fraction, and potential added value as an ingredient fish feeds. Here we test bulk replacement PPB microbial in diets Asian sea...
Abstract Aquaculture is playing an increasingly important role in global food security, especially for low-income and food-deficit countries. The majority of aquaculture production occurs freshwater earthen ponds tilapia has quickly become one the most widely adopted culture species these systems. Tilapia are now farmed over 140 countries facilitated by their ease production, adaptability to a wide range environmental conditions, fast growth, high nutritional value. Typically, have been...
Abstract Tilapia is an affordable protein source farmed in over 140 countries with the majority of production low‐ and middle‐income countries. Intensification tilapia farming has exacerbated losses caused by emerging re‐emerging infectious diseases. Disease diagnostics play a crucial role biosecurity health management to mitigate disease loss improve animal welfare aquaculture. Three continuous levels (I, II III) for aquatic species have been proposed Food Agriculture Organization United...
Early developmental stages of tilapia, including fertilized eggs were tested positive for TiLV in our previous study (Dong et al., 2017a). We, therefore, hypothesized that infected broodstock is able to pass the virus their reproductive organs and then eggs. In order prove this hypothesis, Nile tilapia (Oreochromis niloticus) experimentally with by intramuscular injection non-infected used as control group. At day 6 post infection, semen from each breeding pair aseptically collected vitro...
Egypt is the topmost aquaculture producer in Africa and third largest tilapia globally. Nile particular cornerstone of fish farming Egypt. Recently, farms have experienced unusual mortality during summer season, threatening further growth sector. In order to understand risk factors, a questionnaire based cross-sectional study was conducted using epidemiology health economics online survey tools. We surveyed 113 four governorates (Kafr El Sheikh, Beheira, Sharqia, Faiyum) one governorate with...
Abstract Antimicrobial resistance is a global public health crisis with attention focussed on food supply as part of the ‘One Health’ integration veterinary, environmental and health. Aquaculture has been fastest growing livestock sector in recent decades critical to nutritional security many low‐ middle‐income countries (LMIC). With ready access antibiotics limited availability veterinary support, disease control poorly informed, often unrecorded high where aquaculture growth fastest....
Irrational and inappropriate use of antibiotics in aquaculture can contribute to the development antibiotic resistance. In this study, we aimed assess usage inland coastal fish farms Bangladesh identify factors associated with practice. We conducted a cross-sectional study collect information from 672 farmers Bangladesh. The frequency use, types antibiotics, purpose usage, prescribing practices were estimated. Adjusted odds ratios (aOR) calculated measure association between related...
Abstract The emergence of antibiotic‐resistant bacteria (ARBs) and genes (ARGs) in aquaculture underscores the urgent need for alternative veterinary strategies to combat antimicrobial resistance (AMR). These measures are vital reduce likelihood entering a post‐antibiotic era. Identifying environmentally friendly biotechnological solutions prevent treat bacterial diseases is crucial sustainability minimizing use antimicrobials, especially antibiotics. development probiotics with...
The gene of RNA viruses, encoding RNA-directed polymerase (RdRp) is relatively conserved due to its crucial function in viral genome replication and transcription making it a useful target for genetic diversity study PCR detection. In this study, we investigated the 21 tilapia lake virus (TiLV) segment 1 sequences predictively coding RdRp subunit P1. Those were obtained from infected fish samples collected Ecuador, Israel, Peru, Thailand between 2011 2019 (nine 12 GenBank). Primers then...
Background Tilapia tilapinevirus , also known as tilapia lake virus (TiLV), is a significant that responsible for the die-off of farmed across globe. The detection and quantification using environmental RNA (eRNA) from pond water samples represents potentially non-invasive routine strategy monitoring pathogens early disease forecasting in aquaculture systems. Methods Here, we report simple iron flocculation method concentrating viruses water, together with newly-developed hydrolysis probe...
Bacterial diseases can pose a significant challenge to aquaculture in Kenya, leading economic losses. A fish farm Narok County, reported mass mortality among its reared which included Nile tilapia, catfish and ornamental fish. This study aimed characterize an Aeromonas isolate recovered from the assess potential role outbreak. Water samples (n=10) were collected randomly different points within ponds using sterile universal bottles transported bacteriology laboratory at Department of...
The growth of Zambia’s aquaculture sector has brought significant economic opportunities while also introducing challenges related to fish health management. This study investigated the prevalence and distribution Epizootic Ulcerative Syndrome (EUS), Lactococcosis, Tilapia Lake Virus (TiLV) across wild farmed populations in Zambia. A total 349 samples were collected from seven districts, encompassing eight species. EUS was detected six species, including rendalli (10.3%),...
Abstract Tilapia lake virus (TiLV) is an emerging pathogen in aquaculture, reportedly affecting farmed tilapia 16 countries across multiple continents. Following early warning 2017 that TiLV might be widespread, we executed a surveillance programme on grow‐out farms and hatcheries from 10 districts of Bangladesh 2019. Among experiencing unusual mortality, eight out 11 tested positive for 2017, two seven Investigation asymptomatic broodstock collected revealed six TiLV. Representative samples...
Streptococcus agalactiae (group B [GBS]) causes disease in a wide range of animals. The serotype Ib lineage is highly adapted to aquatic hosts, exhibiting substantial genome reduction compared with terrestrial conspecifics. Here, we sequence genomes from 40 GBS isolates, including 25 isolates wild fish and captive stingrays Australia, six local veterinary or human clinical nine farmed tilapia Honduras, them 42 public databases. Phylogenetic analysis based on nonrecombinant core-genome single...
Yersinia ruckeri is a salmonid pathogen with widespread distribution in cool-temperate waters including Australia and New Zealand, two isolated environments recently developed farming industries. Phylogenetic comparison of 58 isolates from Australia, USA, Chile, Finland China based on non-recombinant core genome SNPs revealed multiple deep-branching lineages, most recent common ancestor estimated at 18 500 years BP (12 355–24 757 95% HPD) evidence Australasian endemism. Evolution within the...
The role of aquatic animals in global food and nutrition security is increasingly recognised. demand for fish increasing, leading to a need significantly increase its supply. Securing future supplies through sustainable production challenge as major resources such fresh water land are becoming limited worldwide. Aquaculture capture fisheries face various threats from both human-mediated natural environmental change, including climate change. systems practices vulnerable changes. Moreover,...
Antigen presentation is a critical step bridging innate immune recognition and specific memory. In mammals, the process orchestrated by dendritic cells (DCs) in lymphatic system, which initiate clonal proliferation of antigen-specific lymphocytes. However, fish lack classical system there are currently no cellular markers for DCs fish, thus antigen-presentation poorly understood. Recently, antigen-presenting similar structure function to mammalian were identified various including rainbow...
Abstract In recent years, Egyptian tilapia aquaculture has experienced mortality episodes during the summer months. The causative agents responsible for such mortalities have not been clearly identified. A total of 400 fish specimens were collected from affected farms within five governorates. 344 bacterial isolates identified examined specimens. Bacterial grouped into seven genera based on API 20E results. most prevalent pathogens Aeromonas spp. (42%), Vibrio (21%), and Streptococcus...
