The pharmacokinetics, bioavailability, and disposition of oxolinic acid (OA), a quinolone antibacterial drug, were examined in a warmwater (channel catfish (Ictalurus punctatus)) and coldwater fish species (rainbow trout (Oncorhynchus mykiss)). Studies were performed at 24 and 14 °C for catfish and at 14 °C for trout to compare temperature- and species-related differences. Analysis of OA pharmacokinetics when determined by HPLC provided elimination half-life [Formula: see text], volume of distribution (Vss), and clearance (Clb) estimates for 24 °C catfish, 14 °C catfish, and 14 °C trout of 40.9, 69.3, and 81.3 h, 939, 880, and 1817 mL/kg, and 16.3, 8.9, and 16.9 mL∙kg∙h−1, respectively. Following oral administration, OA plasma concentrations peaked between 8 and 24 h for all treatments; however, 14 °C trout and 14 °C catfish sustained peak concentrations for a longer duration than 24 °C catfish. Oral OA bioavailabilities were 56.0, 91.8, and 90.7% for 24 °C catfish, 14 °C catfish, and 14 °C trout, respectively. OA distribution data for muscle of 14 °C catfish demonstrated an inordinately high peak concentration and delayed time to peak relative to other treatments. Elimination half-lives of OA in muscle were 33.1, 54.3, and 141 h for 24 °C catfish, 14 °C catfish, and 14 °C trout, respectively.

Aquacultured rainbow trout (Oncorhynchus mykiss) and channel catfish (Ictalurus punctatus) fillets were inoculated with the psychrotrophic pathogens Listeria monocytogenes and Aeromonas hydrophila: cell populations were monitored during refrigerated storage at 2 to 4°C. Fillets of both species were placed individually in sterile plastic bags and inoculated with cell suspensions (104.7 CFU/100 g of fish) of either A. hydrophila or L. monocytogenes or of both A. hydrophila and L. monocytogenes, for a total of three treatments for each species of fish. Each inoculum and fillet were mixed to ensure uniform distribution and then stored at 2 to 4°C. A. hydrophila, L. monocytogenes, and aerobio cell populations were determined on days 1, 3, 6, 8, 10, 13, and 15. Individually inoculated A. hydrophila and L. monocytogenes grew on catfish and trout fillets during the 15-day study. There was no inhibition of either pathogen by the natural flora on the fillets. Both psychrotrophic pathogens grew equally well in catfish and trout fillets inoculated with a combination of A. hydrophila and L. monocytogenes. In all three treatments, the counts of the psychrotrophic pathogens were lower than the aerobic plate counts. The growth of the psychrotrophic pathogens L. monocytogenes and/or A. hydrophila during refrigerated storage on aquacultured fish fillets could increase the food hazard risk, particularly where there is a possibility of cross-contamination with ready-to-eat food products.

<em>Abstract.-</em>The Arkansas Game and Fish Commission’s Family and Community Fishing Program was developed in 2002, and catchable channel catfish <em>Ictalurus punctatus</em>, hybrid striped bass <em>Morone saxatilis </em>x <em>M. chrysops</em>, and rainbow trout <em>Oncorhynchus mykiss </em>have been stocked into ponds and streams seasonally each subsequent year. One of the goals of the program has been to provide families and children with a convenient and excellent chance to catch fish. A toll-free stocking hotline (1-866-540-FISH) was initiated in January 2006 to inform anglers when and where fish had been stocked, so they could plan their fishing trips to program destinations accordingly. Hotline information was provided for 22 ponds during catfish season (April through November) and 17 ponds plus one stream during trout season (December through March). The hotline was generally updated within two hours after stocking, and consisted of information regarding immediate past stocking events as well as general fishing tips. Anglers placed 11,822 calls and spent 15,394 min of call-time on the hotline between January 2006 and May 2007. The number of calls peaked during catfish stocking season in June and was lowest during the September stocking off-season. On average, the hotline cost approximately $40 per month to operate and was four to six times less expensive than paying Commission personnel to answer stocking questions on the telephone. More than 36% of the hotline calls were placed outside of Commission business hours (0800-1630 hours), indicating that anglers were taking advantage of the 24-h information line. A toll-free hotline is a popular, inexpensive, and cost-effective means of supplying stocking information, allowing anglers to make informed decisions when choosing a day and location to fish at program locations.

Abstract A method was validated to simultaneously determine and confirm melamine and cyanuric acid in fish kidneys by LC/MS/MS. This method is capable of detecting both compounds in a single procedure, whether present as free compounds or bound together as the melamine–cyanurate complex in both channel catfish (Ictalurus punctatus) and rainbow trout (Oncorhynchus mykiss) kidneys. Residues are extracted with no additional cleanup and analyzed by LC/MS/MS using external standard calibration. The method is capable of quantifying residues over a range of 0.4 to 50 μg/g. For both compounds and species of fish tested, the LOD is estimated to be 0.1 μg/g and the LOQ 0.4 μg/g. Recoveries and RSDs are 83 to 101% and 2 to 8%, respectively. In catfish, matrix effects are higher for melamine than cyanuric acid. In rainbow trout, similar matrix effects are found for both compounds.
