Survival of monosex grass carp in small ponds
Little information is available on the survival of grass carp (Ctenopharyngodon idella) in ponds &mdash especially on the survival of fry to large fingerling stage, during the time when the most mortality would be expected. Development of monosex (all female) grass carp at the Fish Farming Experimental Station by the technique of artificial gynogenesis (Stanley et al. 1975) enabled us to observe s

Renal excretion in channel catfish following injection of quinaldine sulphate or 3-trifluoromethyl-4-nitrophenol
Channel catfish, Ictalurus punctatus Rafinesque, injected intraperitoneally with 2-methyl-quinoline sulphate (QdSO4) or 3-trifluoromethyl-4-nitrophenol (TFM) eliminate most of the dose of these compounds by extra-renal routes. Patterns of renal excretion of Na+, K+, Ca2+, Mg2+, and Cl- (pEq kg-1 h-1) appeared to be associated with the 'stress' of the urine collection technique rather than with the

Effects of tide cycles on habitat selection and habitat partitioning by migrating shorebirds
We studied assemblages of feeding shorebirds in three intertidal habitats on the coast of New Jersey during August to document how species segregate spatially both among and within habitats and to determine the effects of tidal cycles on these patterns. The habitats were a sandy beach facing the ocean proper (outer beach), a sandy beach on the mainland side of a barrier island (inner beach), and a
