Growth, morphometrics, and nutrient content of farmed eastern oysters, (Gmelin), in New Hampshire, USA.

Aquac Res 2017 Apr;48(4):1525-1537

United States Environmental Protection Agency, Office of Research and Development, National Human and Environmental Effects Research Lab, Atlantic Ecology Division, Narragansett, RI 02882 USA.

When harvested, oysters represent a removal from the ecosystem of nutrients such as nitrogen (N) and carbon (C). A number of factors potentially affect nutrient content, but a quantitative understanding across the geographic range of the eastern oysters is lacking. The present study was designed to quantify the relationships among various metrics of farmed eastern oysters near its northern geographic range focusing on nutrient content. Read More

Vitrification of Sperm from Marine Fishes: Effect on Motility and Membrane Integrity.

Aquac Res 2015 Jun;46(7):1770-1784

Aquaculture Research Station, Louisiana Agricultural Experiment Station, Louisiana State University Agricultural Center, Baton Rouge, LA 70803, USA.

Our goal was to develop a standardized approach for sperm vitrification of marine fishes that can be applied generally in aquatic species. The objectives were to: 1) estimate acute toxicity of cryoprotectants over a range of concentrations; 2) evaluate the properties of vitrification solutions (VS); 3) evaluate different thawing solutions, and 4) evaluate sperm quality after thawing by examination of motility and membrane integrity. Sperm were collected from red snapper (), spotted seatrout (), and red drum (). Read More

Simulation modeling of high-throughput cryopreservation of aquatic germplasm: a case study of blue catfish sperm processing.

Aquac Res 2015 Feb;46(2):432-445

Aquaculture Research Station, Louisiana Agricultural Experiment Station, Louisiana State University Agriculture Center, Baton Rouge, LA 70803.

Emerging commercial-level technology for aquatic sperm cryopreservation has not been modeled by computer simulation. Commercially available software (ARENA, Rockwell Automation, Inc. Milwaukee, WI) was applied to simulate high-throughput sperm cryopreservation of blue catfish () based on existing processing capabilities. Read More

Environmental effects of a marine fish farm of gilthead seabream () in the NW Mediterranean Sea on water column and sediment.

Aquac Res 2015 Jan 11;46(1):59-74. Epub 2013 Mar 11.

Institutd'Investigació per a la GestióIntegrada de Zones Costaneres (IGIC). Universitat Politècnica de València Grau de Gandia València Spain.

This study examined the effects of organic enrichment on water column, sediments and macrofauna caused by a fish farm in the Mediterranean Sea. Samples were collected on four sampling campaigns over a one-year cycle. Significant differences were found in the water column in dissolved oxygen, dissolved inorganic nitrogen, phosphate and total phosphorus concentrations between the fish farm and the control.

Gene expression kinetics of the yellow head virus in experimentally infected .

Aquac Res 2010 Sep 21;41(10):1432-1443. Epub 2009 Dec 21.

Marine Biotechnology, CIAD, Hermosillo, Son, México.

The yellow head virus (YHV) has been reported to be one of most pathogenic viruses for cultivated shrimp; however, serious problems have only been reported in farms in south and southeastern Asian. Recently, a YHV strain was detected in cultivated in Mexican farms that lacked virus-associated mortalities or epizooties, and the animals were apparently healthy. The identity of the virus was confirmed by sequencing replicative and structural protein-encoding regions and comparing with homologous virus sequences. Read More

Yellow head-like viruses affecting the penaeid aquaculture industry: a review.

Aquac Res 2007 Jun 5;38(9):893-908. Epub 2007 Jun 5.

Microbiology and Immunology, James Cook University, Townsville, Qld, Australia.

This review focuses on relevant scientific information regarding the current knowledge of the yellow head complex viruses, yellow head virus and gill-associated virus. The yellow head complex viruses have been problematic within the aquaculture industry for over 10 years and still retain their research topicality. Presently, there are numerous research papers from different journals covering the identification, disease expression and spread, pathogenesis, detection, morphology, genomic sequence and protein profiles of the yellow head complex viruses.
