The 'robust' capture-recapture design allows components of recruitment to be estimated The 'robust' capture-recapture design allows components of recruitment to be estimated
The 'robust' capture-recapture design (Pollock 1982) allows analyses which combine features of closed population model analyses (Otis et aI., 1978, White et aI., 1982) and open population model analyses (Pollock et aI., 1990). Estimators obtained under these analyses are more robust to unequal catch ability than traditional Jolly-Seber estimators (Pollock, 1982; Pollock et al., 1990...

Radiocarbon ages from two submerged strandline features in the western Gulf of Maine and a sea-level curve for the northeastern Massachusetts coastal region Radiocarbon ages from two submerged strandline features in the western Gulf of Maine and a sea-level curve for the northeastern Massachusetts coastal region
New radiocarbon dates provide ages for two submerged strandline features on the Massachusetts inner shelf. These ages provide limited control on a relative sea-level (RSL) curve for the late Wisconsinan and Holocene. The curve indicates a late Wisconsinan high stand of RSL of +33 m about 14,000 yr ago and a very short-lived relative low stand of about -43 m at about 12,000 yr ago...

An in vitro technique for surveying immunostimulants in fish An in vitro technique for surveying immunostimulants in fish
In vitro assays were developed to investigate the effects of immunostimulants on leukocytes in spleen sections of rainbow trout (Oncorhynchus mykiss). Fish spleens were divided, and individual sections were placed in 10 ml of tissue culture media and 0.1, 1, 10, or 100 μg/ml dilutions of Levamisole, QAC (quaternary ammonium compound), or ISK (a polypeptide). After 4 days of incubation...

Glucan injection or bath exposure given alone or in combination with a bacterin enhance the non-specific defence mechanisms in rainbow trout (Oncorhynchus mykiss) Glucan injection or bath exposure given alone or in combination with a bacterin enhance the non-specific defence mechanisms in rainbow trout (Oncorhynchus mykiss)
Elevations in the non-specific defence mechanisms were noted after trout were injected or bathed in glucan solutions or in solutions containing the glucan combined with a bacterin, Y. ruckeri O-antigen. Periodic non-lethal blood samples showed that neutrophil activity as evaluated by the ability of the cells to stick to glass and produce oxidative radicals as detected by the nitroblue...

Effects of dietary selenium and vitamin E on red blood cell peroxidation, glutathione peroxidase activity, and macrophage superoxide anion production in channel catfish Effects of dietary selenium and vitamin E on red blood cell peroxidation, glutathione peroxidase activity, and macrophage superoxide anion production in channel catfish
Fingerling channel catfish Ictalurus punctatus were fed purified diets either unsupplemented and deficient in both selenium and vitamin E, deficient in either selenium or vitamin E, adequate in both selenium (0.2 mg/kg) and vitamin E (60 mg/kg), or excessive in both nutrients (four times the recommended levels). After 115–120 d of feeding the experimental diets, the red blood cell...

Water Resources Data, New Jersey, Water Year 1992, Volume 1. Surface-Water Data Water Resources Data, New Jersey, Water Year 1992, Volume 1. Surface-Water Data
Water resources data for the 1992 water year for New Jersey consists of records of stage, discharge, and water quality of streams; stage, contents, and water quality of lakes and reservoirs; and water levels and water quality of ground water. This volume of the report contains discharge records for 99 gaging stations; tide summaries for 2 stations; stage and contents for 37 lakes and...

Effects of salinity on chloride cells and Na+ K+-ATPase activity in the teleost Gillchthys mirabilis Effects of salinity on chloride cells and Na+ K+-ATPase activity in the teleost Gillchthys mirabilis
1. Longjawed mudsuckers, Gillichthys mirabilis, in 30ppt seawater (SW) were transferred to 1.5, 30 and 60ppt SW. 2. In the first 1–3 days after transfer, plasma chloride level and plasma osmolarity rose in the 60ppt SW fish, and decreased in the 1.5ppt SW fish. 3. By day 21, however, plasma chloride and osmolarity were at or near the levels seen in the controls (30ppt). 4. Branchial and...

Effects of feeding a high level of D-glucose on liver function juvenile white sturgeon (Acipenser transmontanus) Effects of feeding a high level of D-glucose on liver function juvenile white sturgeon (Acipenser transmontanus)
Juvenile white sturgeon (Acipenser transmontanus) were fed three isonitrogenous and isoenergetic diets containing either 35% D-glucose (HC), a mixture of 20% dextrin and 10% cellulose (MC), or 23% cellulose (LC), to investigate the effects of dietary carbohydrate on liver function. After 8-week feeding, body weight gain of fish fed the HC diet was consistently higher than that of fish...

Fluorspar Fluorspar
The U.S. produced 50 kt of fluorspar in 1992 and imported nearly 409 kt. Almost all the fluorspar was imported from China. The U.S. consumption of 467 kt represents the lowest level since 1958. This is due to the continuing decrease in consumption by the steel and aluminum industries.
