Comparison of Growth and Production of Green and Red Salanova Lettuce (Lactuca sativa) and Basil (Ocimum basilicum) When Grown in Either Floating Rafts or Media Beds in a Coupled Aquaponic System with Nile Tilapia (Oreochromis niloticus)

Joshua C. Dusci, Zoe Babb, Benjamin H. Beck, Carl D. Webster

This study compared floating raft and media bed aquaponic systems, assessing fish growth, plant growth, and system performance between common system designs. The study consisted of two trials utilizing six replicated aquaponic systems. In each trial, three of the systems were floating …

Temporal transcriptomic profiling of channel catfish (Ictalurus punctatus) gills after acute copper exposure reveals suppressed immune gene responsiveness to Flavobacterium covae infection

Jason W. Abernathy, Yesutor K. Soku, Nithin Muliya Sankappa, Miles D. Lange et autres

Copper sulfate pentahydrate (CuSO 4 ·5H 2 O) is widely used as a chemical prophylactic in aquaculture, yet its immunomodulatory effects in fish remain poorly understood. Here, we investigated how the timing of CuSO 4 exposure shapes early immune responses and survival …

Single-cell transcriptome characterization of channel catfish (Ictalurus punctatus) B lymphocyte cell lines

Johanna E. Aldersey, Miles D. Lange, Benjamin H. Beck, Jason Abernathy

In channel catfish ( Ictalurus punctatus ), immortalized cell lines that represent different lymphoid cell types have previously been developed and used to study teleost immune function. The 3B11 and 1G8 B cell lines were developed through mitogen stimulation and were the …

The Effects of Peracetic Acid on Post‐Larvae and Juvenile Pacific White Shrimp ( Litopenaeus vannamei ) and Seven Vibrio Species Isolates at Two Salinities

James T. Tuttle, Timothy J. Bruce, Luke A. Roy, Hisham A. Abdelrahman et autres

ABSTRACT Pacific white shrimp ( Litopenaeus vannamei ) are among the most important aquaculture species but are highly susceptible to Vibrio infections. Novel disease management strategies are necessary. Previous studies have reported that peracetic acid (PAA) is an effective disinfectant, but its …

Efficacy of an Inactivated Bacterin Vaccine Against Emerging Streptococcus dysgalactiae in Channel Catfish ( Ictalurus punctatus )

Brent M. Vuglar, Krishna P. Singha, Craig A. Shoemaker, Benjamin H. Beck et autres

Lancefield Group C Streptococcus dysgalactiae recently emerged as a catfish pathogen in the US. Reports from hatcheries suggest S. dysgalactiae causes substantial broodfish loss. We aimed to develop a challenge model and evaluate vaccine efficacy against S. dysgalactiae in juvenile channel catfish …

Passive immunization with anti-virulent Aeromonas hydrophila whole serum protects Channel Catfish against motile Aeromonas septicemia

Allison L. Wise, Benjamin H. Beck, Troy J. Bader, Benjamin R. LaFrentz et autres

OBJECTIVE: Recently, we demonstrated the efficacy of oral bacterin virulent Aeromonas hydrophila (vAh) vaccines (S14-452 and ML09-119) in Channel Catfish Ictalurus punctatus, but gaps in knowledge exist with respect to protective immunity induced by vAh bacterins. Specific antibodies were proposed as a …

Long‐Term Effects of a Dietary Humic Substance–Butyrate Blend, and Yeast Cell Wall on Growth Performance, Immune Status and Gut Microbiota of Juvenile Channel Catfish Ictalurus punctatus

Abdulmalik A. Oladipupo, Anita M. Kelly, D. Allen Davis, Benjamin H. Beck et autres

ABSTRACT This study evaluated the long‐term effects of a dietary humic substance and butyrate blend (HSB) alone or with yeast cell wall (Beta‐MOS) in channel catfish. Around 1440 fish (31.31 ± 0.24 g) were distributed among 12 outdoor tanks in a pond‐supplied …

Genome sequencing and hybrid assembly of novel Streptococcus dysgalactiae isolates recovered from both juvenile and broodstock channel catfish

Jason Abernathy, Craig A. Shoemaker, John D. Konvalina, Julio C. García et autres

is an emerging pathogen in fish, causing septicemia, tissue damage, and production losses. We sequenced, assembled, and annotated genomes from multiple isolates recovered from a commercial catfish farm. These genomic data advance our understanding of streptococcosis in fish and support the development …

Situation of aquatic animal diseases in Thailand (January-June 2024)

Sanpoom Boonyarat

Aquaculture in Thailand has a long history due to the country's abundant resources, which are well-suited for raising both freshwater and marine species. The main aquatic species farmed in Thailand are shrimp and fish. For shrimp, common species include Pacific white shrimp …

Susceptibility of Ictavirus acipenseridallo2 , White Sturgeon iridovirus, and ranaviruses to buffered povidone iodine complex, chlorine, and Virkon Aquatic

Esteban Soto, Susan Yun, Kuttichantran Subramaniam, Amber E Johnston et autres

Abstract Objectives Ictavirus acipenseridallo2 (AciHV-2), White Sturgeon iridovirus (WSIV), Ranavirus rana1 (RR1), and Ranavirus alytes1 (RA1) are important viral pathogens of cultured sturgeon. The purpose of this study was to identify the virucidal efficacy of household bleach (free chlorine), a buffered povidone …
