fish larvae have a high requirement of amino acid (aa) for energy production and growth. this study was aimed to increase knowledge of aa profile during feral carp larval ontogeny and estimate larval aa requirements. larvae were collected randomly at 1, 3, 7, 11, 15, 19, 26 and 33 days post hatch for growth and aa analysis. the composition of total aa changed significantly during ontogeny. the ...

Sustainability and further development of aquaculture production are constantly challenged by outbreaks of fish diseases, which are difficult to prevent or control. Developing fish strains that are genetically resistant to a disease is a cost-effective and a sustainable solution to address this challenge. To do so, heritable genetic variation in disease resistance should be identified and combi...

Experimental studies of foot-and-mouth disease (FMD) in feral swine are limited, and data for clinical manifestations and disease transmissibility are lacking. In this report, feral and domestic swine were experimentally infected with FMDV (A24-Cruzeiro), and susceptibility and virus transmission were studied. Feral swine were proved to be highly susceptible to A-24 Cruzeiro FMD virus by intrad...

Invasive feral swine (Sus scrofa) cause extensive damage to agricultural and wildlife resources throughout the United States. Development of sodium nitrite as a new, orally delivered toxicant is underway to provide an additional tool to curtail growth and expansion of feral swine populations. A micro-encapsulation coating around sodium nitrite is used to minimize detection by feral swine and ma...

Feral pigs (Sus scrofa) are an exotic ungulate which have been widely introduced worldwide with multiple ecosystem and economic consequences. The author conducted a semi-comprehensive literature review directed at identifying the current state of knowledge related to the effects of feral pigs on island and mainland plant and animal communities. Also, the author describes the situation in Califo...

Feral swine (Sus scrofa) are present in 38 of the 50 United States, and their populations continue to expand. Domestic swine are widely regarded as vulnerable to diseases harbored by feral swine. Our objectives were to determine antibody prevalence for selected pathogens in Texas feral swine populations and identify contact events between feral and domestic swine. Overall prevalence of antibodi...

OBJECTIVE To compare seroprevalences of antibodies against Bartonella henselae and Toxoplasma gondii and fecal shedding of Cryptosporidium spp, Giardia spp, and Toxocara cati in feral and pet domestic cats. DESIGN Prospective cross-sectional serologic and coprologic survey. ANIMALS 100 feral cats and 76 pet domestic cats from Randolph County, NC. PROCEDURE Blood and fecal samples were col...

introduction:cats carry a lot of zoonotic parasites such as toxoplasma gondii which causes toxoplasmosis in warm-blooded animals. toxoplasmosis includes wide range of symptoms in its intermediate and definitive hosts but the worst symptoms have been seen in pregnant women and also on immunocompromised hosts. considering the importance of cats as the only definitive host that spread the t. gondi...

Feral cats are abundant in the Hawaiian Islands and pose a threat to native wildlife through predation and the spread of disease. A combination of factors including the submission of state bills and county resolutions has created the impression that a large segment of society supports the presence of feral cats in the islands and in-situ management techniques. The purpose of this research was t...
