Constituents From Brazilian Propolis Against Edwardsiella ictaluri and Flavobacterium covae, Two Bacteria Affecting Channel Catfish (Ictalurus punctatus).

Edwardsiella ictaluri and Flavobacterium covae are two bacteria species that cause diseases in farm-raised channel catfish (Ictalurus punctatus) that cause heavy economic damage to the aquaculture industry, particularly to the channel catfish farming. In search for environmentally benign antibacterial compounds active against E. ictaluri and F. covae, we investigated the constituents isolated from Brazilian red, brown and green propolis. We have also synthetically modified active constituents to see if lipophilicity plays a role in enhancing antibacterial activities. Vestitol, neovestitol and methylvestitol were found to be the active constituents with minimum inhibitory concentration (MIC) relative to drug control florfenicol (RDCF) values (MIC-RDCF) of 7.6, 7.6 and 7.9 mg/L, respectively, against F. covae. The activity against E. ictaluri was not significant.

The increasing volume of wastewater from fish farming poses a serious environmental threat. This study investigated a novel treatment method for butter catfish (Ompok bimaculatus) wastewater using a constructed wetland-microbial fuel cell (CW-MFC) integrated with the water fern Azolla microphylla. The system was effectiveness in removing pollutants like electrical conductivity (EC), total dissolved solids (TDS), ammonium, nitrate, nitrite, and phosphate was evaluated. Additionally, the electricity generation capabilities were measured. The CW-MFC system achieved significant removal rates: 67.65% for EC, 61.67% for TDS, 100% for ammonium, 75.00% for nitrate, 81.25% for nitrite, and 70.00% for phosphate. Furthermore, the system generated a maximum open-circuit voltage (OCV) of 690±90 mV, a current density (CD) of 7.29±0.43 mA/m³and a power density (PD) of 0.37±0.04 mW/m³. Analysis of the microbial community revealed a diverse root consortium dominated by bacterial genera including Phreatobacter, Emticicia and Rhodobacter, along with fungal genera such as Strelitziana, Ramularia, Cladosporium,Trichomerium, Cercospora, Erythrobasidium and Fusarium. These findings suggest that CW-MFC systems integrated with A. microphylla offer a promising approach for sustainable and efficient treatment of wastewater from catfish farming while simultaneously generating bioelectricity.

Innate and adaptive immunity gene expression profiles induced by virulent Aeromonas hydrophila infection in the immune-related organs of channel catfish

Aeromonas hydrophila causes motile Aeromonas septicemia (MAS) in freshwater fish. In recent years, MAS outbreaks due to virulent Aeromonas hydrophila (vAh) have been responsible for large-scale losses within commercial catfish farms in Mississippi and Alabama. The aim of this study was to evaluate immune gene expression in catfish immune-competent tissues during infection with vAh strain ML09-119. Specific pathogen-free catfish fingerlings were intraperitoneally infected with vAh strain ML09-119, and relative expression of thirteen immune-related genes was evaluated from head kidney, spleen, and liver. Our results revealed that vAh was detected 2 h post-infection (hpi) in the head kidney, liver, and spleen. The highest concentration of vAh was detected at 12 hpi, from which point concentrations decreased until clearance at 5 days post-infection (dpi). Gene expression analysis revealed upregulation of pro-inflammatory cytokines and innate immune response (TLR 4 and 5) in the first 24 hpi. Adaptive immune-related genes were upregulated at 7 dpi in the spleen and 14 dpi in the head kidney. Furthermore, immunoglobulin M showed significant upregulation at 14 dpi in the head kidney and 21 dpi in the spleen. In summary, vAh ML09-119 infection induced a strong inflammatory response involving multiple innate immunity genes, proinflammatory cytokines, and chemokines. Surviving catfish were able to clear the infection and produce antibodies and memory cells. Assessment of the immunological response to vAh infection is critical for understanding the pathogen's mechanisms of pathogenesis and developing means for MAS control, including vaccine development and improved treatments.

THE USE OF MOBILE PHONES BY CATFISH FARMERS AT UTEH FISH FARMING CLUSTER IN BENIN CITY, NIGERIA

It is important to understand how catfish farmers use mobile phones in their business activities to enhance the adoption and utilization of mobile phones in fish farming. The study assessed catfish farmers' use of mobile phones for business activities at Uteh fish farming cluster, Edo State, Nigeria. The study examined the business activities mobile phones are used for, the fish farmers' perceived competence, and the challenges faced in using their mobile phones. Data were collected from 71 catfish farmers at the Uteh fish farming cluster through convenience sampling, using a structured interview schedule. Frequency counts, Percentages, means, and correlation were used to analyze the data. The results show the average age of the farmers to be 44 years, farmers were mostly (71.8%) male, and about 90% of them were married. All (100%) of the fish farmers indicated that they used their mobile phones for basic business activities like receiving calls and sending SMS, using social media apps such as WhatsApp, contacting buyers, and taking pictures for business. The Catfish farmers were competent in the use of mobile phones except in obtaining loans (mean = 2.42), using aquaculture apps (mean = 2.62), and checking weather forecasts (mean = 3.62). However, the use of mobile phones by the catfish farmers was constrained by poor network coverage.

The effect of blood meal to induce aquaculture performance of striped catfish (Pangasionodon hypophthalmus Sauvage, 1878)

Abstract The high price of fish meal as feed is the main problem in cultivating striped catfish. The use of blood meal, waste from slaughterhouses, can be an alternative to improve aquaculture performance while reducing feed costs. This research aimed to determine the effect of using blood meal as a source of feed protein on the growth performance of striped catfish. The research design used was a Completely Randomized Design (CRD) consisting of five treatments and three replications. The treatments used were A (blood meal 0%, fish meal 100%) as control, B (blood meal 25%, fish meal 75%), C (blood meal 50%, fish meal 50%), D (blood meal 75%, fish meal 25%), and E (blood meal 100%, fish meal 0%). The results showed that the average body weight and specific growth in treatments B (8.25 ± 0.63b g, 3.51 ± 0.13b %/day) and C (8.26 ± 0.73b g, 3.52 ± 0.14b %/day) had the same performance as the control. It is concluded that blood meal can be substituted and combined with fish flour with a maximum composition of 50% to improve the performance of striped catfish aquaculture. Further research to increase the nutrition of blood meal must be conducted to improve the aquaculture performance of striped catfish.

Exploring the Effectiveness of Acyclovir against Ranaviral Thymidine Kinases: Molecular Docking and Experimental Validation in a Fish Cell Line.

The effectiveness of acyclovir, a selective anti-herpesvirus agent, was tested both in silico and in vitro against two ranaviruses, namely the European catfish virus (ECV) and Frog virus 3 (FV3). ECV can cause significant losses in catfish aquaculture, while FV3 poses a risk to vulnerable amphibian populations. The genome of ranaviruses encodes thymidine kinases (TKs) similar to those of herpesviruses. Molecular docking simulations demonstrated that the acyclovir molecule can bind to the active sites of both investigated viral TKs in an orientation conducive to phosphorylation. Subsequently, the antiviral effect of acyclovir was tested in vitro in Epithelioma Papulosum Cyprini (EPC) cells with endpoint titration and qPCR. Acyclovir was used at a concentration of 800 µM, which significantly reduced the viral loads and titers of the ranaviruses. A similar reduction rate was observed with Ictalurid herpesvirus 2, which was used as a positive control virus. These promising results indicate that acyclovir might have a wider range of uses; besides its effectiveness against herpesviruses, it could also be used against ranavirus infections.

Comparison of fish biological indicators of Clarias gariepinus hybrids grown in ras and pond farming conditions

To improve technologies in the field of commercial cultivation of aquaculture objects and further development of the warm-water aquaculture sector in Russia, we previously undertook breeding methods and approaches to obtain high-quality planting material for a promising commercial object — the African catfish Clarias gariepinus. This article presents, in a comparative aspect, the experience of growing hybrid offspring of African catfish, obtained from crossing two breeds — Mikhailovskaya and Tamanskaya, in a closed water supply system and in a pond farm in the Astrakhan region in the summer. It was shown that hybrid individuals of clariid catfish bred in a pond farm during the feeding period under consideration (from July to September) were characterized by a high specific growth rate and low feed ratio compared to hybrids grown in a recirculation system, respectively, 11.4% versus 9.87% and 0.96 versus 1. Also, based on the results of fishing, over two months of cultivation in a pond farm, hybrids of clariid catfish increased the total biomass by 13 times, while in a recirculating system it increased by 15 times, but the final biomass of fish turned out to be greater when reared in open reservoir (46.875 versus 10.87 kg). It was shown that the final individual mass of hybrid fish cultured in pond conditions was 11.0% higher than the final mass of individuals in the recirculation system. The conducted studies showed that in the climatic conditions of the Astrakhan region (VI fish-breeding zone), a promising direction for aquaculture of African catfish is the feeding cultivation of hybrid juveniles in pond farms. It should be taken into account that in order to obtain marketable fish products (i.e. individuals weighing over 1000 g), it is necessary to use fish seeding material with an average weight of at least 100 g.

The impact of shade net use on total nitrogen removal by duckweed (Lemna perpusilla) at different levels of catfish farming effluent

Duckweed (Lemna perpusilla) has been shown to reduce nutrient levels in aquaculture effluent, particularly total nitrogen, which can be caused by a variety of organic contaminants in water. Duckweed biomass is an important source of bioenergy and phytoremediation in aquaculture. This aspect makes it a viable solution for sustainable integrated aquaculture, although appropriate duckweed biomass development is critical to its success and long-term survival. Duckweed growth, as an autotroph, is controlled by two factors: nutrition and sunlight. The aquaculture production cycle changes nutrient content in medium culture based on feed, fish age, and density, while weather influences solar radiation. The study aims to investigate duckweed growth response and phytoremediation capacity by analyzing changes in catfish farming waste-water quality grouped by fish age (L1: 2 months, L2: 3 months, and L3: 4 months) and shade net treatment at 25 % sunlight blocking (N25), 50 % (N50), and no shade net (N0). The experiment was carried out in triplicate in a semi-outdoor growth system placed in a greenhouse. It comprised of three series of duckweed culture containers filled with catfish farming wastewater, each with a working volume of 50 L. A total of 48 duckweed culture containers were floated inside a series of Recirculating Aquaculture System (RAS) tanks. Biomass harvesting and water quality monitoring were done every three days for a period of 18 days. N25 had the highest biomass weight, productivity, and average TN elimination efficiency, with values of 225.21 ± 140.04 g, 50.05 ± 10.06 g/(m2.d), and 61.94 ± 8.01 %, respectively (P < 0.05). The N0 values were 190.80 ± 117.52 g, 42.40 ± 9.29 g/(m2.d), and 55.61 ± 6.85 % (P < 0.05). The lowest values observed in N50 were 72.27 ± 55.70 g, 16.06 ± 4.90 g/(m2.d), and 51.67 ± 4.10 % (P < 0.05). This study proved the optimal duckweed growth and TN removal effectiveness with N25 under varying light intensity, allowing for the long-term use of duckweed in waste management and integrated aquaculture.

Acceptance of farmed African catfish in Egypt: addressing consumer concerns and marketing challenges

African catfish farmers used animal waste as feed to reduce production costs, a practice that raised concerns among consumers, causing them to avoid it. Consequently, this study aimed to explore factors that influenced the acceptance of farmed African catfish. The data survey involving 2294 participants from Egypt was analyzed using descriptive statistics and the chi-square test. The results indicated that 67% of participants abstained from consuming it, while 2.30% consumed it regularly. The chi-square test revealed significant consumption pattern variations (p < 0.05) based on most demographic factors. Entirely, 43% were uninformed about the nutritional value, market availability, and the potential impact of using aquafeeds on pricing. About 55–57% lacked information on feeding practices, had quality concerns, viewed catfish consumption as a health risk, and were unaware of its prices. Additionally, 68% were worried about pollution, and 76% found the available information insufficient. The main reasons for this challenge lie in consumers’ health, religious, and psychological concerns. To address this, we propose a targeted marketing strategy focusing on improving safety and quality through safe and cost-effective aquafeeds. This involves requiring farmers to obtain quality certifications and adhere to best management practices, adding value to the product, and transparent communication with consumers to provide them with reliable information about cultivation practices and the nutritional value of African catfish. Effective collaboration among key stakeholders in implementation, efficient sector management, establishing an activity licensing system, and prohibiting current feeding practices will enhance sustainable demand and reverse the declining production trend of this promising species.

Diversity in clinical isolates of Ictalurid herpesvirus 1 (IcHV1) from U.S. farm-raised catfish and virulence assessment in channel and channel × blue catfish hybrids.

Ictalurid herpesvirus 1 (IcHV1) is the most significant viral agent in U.S. catfish aquaculture. Little is known regarding the genetic stability and antigenic variability of IcHV1. Herein, the genetic and antigenic diversity of IcHV1 field isolates was assessed by restriction fragment length polymorphism (RFLP) analysis and serum neutralization assays. RFLP analysis identified two distinct genotypes (IcHV1A and IcHV1B), both discrete from blue catfish alloherpesvirus (BCAHV). Neutralization assays with anti-IcHV1 monoclonal antibody Mab-95 indicate shared antigenic determinants for IcHV1A and IcHV1B that are absent from BCAHV, which Mab-95 did not neutralize. Virulence assessments with representative isolates demonstrate significant differences between isolates within RFLP groups and pooled RFLP group data suggest IcHV1B (pooled survival [mean ± SE]: 58.3% ± 2.6) may be more virulent than IcHV1A (survival: 68.6% ± 2.4). Rechallenges with representative IcHV1A and IcHV1B isolates indicate a cross-protective effect, with fish surviving initial exposure to IcHV1A or IcHV1B showing robust protection when subsequently re-exposed to IcHV1A or IcHV1B. This work demonstrated significant differences in virulence between case isolates, identifying two discrete IcHV1 lineages, distinct from BCAHV, with similar virulence in channel and channel × blue catfish hybrids and a cross-protective effect in catfish surviving exposure to either lineage.
