Analysis and occurrence of disinfection by-products in fresh and salt water
… DBPs in saltwater and seawater based marine park aquaria. A new rapid and sensitive method was developed for simultaneous analysis of ten brominated and/or iodinated acetic acids, bromate, iodate, bromide, and iodide using ion chromatography-inductively couple plasma-mass spectrometry (IC-ICP-MS). …

Phylogenetic Systematics of Snubnose Darters (Percidae, Etheostoma), With Discussion of Reproductive Behavior, Sexual Selection, and the Evolution of Male Breeding Color
… were significantly longer for pairs spawning in aquaria than for pairs spawning in the field. Egg deposition behavior was similar in streams and aquaria, differing only in the occasional use of substrates not available in natural environments (e.g., fine gravel or aquarium hardware) as egg …

Selection of benthic habitat by yellow-phase American eels (Anguilla rostrata)
… During nine, 4-day trials replicated with three aquaria, American eels were given a choice to burrow into five equally available benthic substrates: cobble (90--256 mm), gravel (4--16 mm), sand (0.125--1 mm), silt/clay (< 0.0625 mm), and leaf pack. Five American eels were used per aquaria for …

Canine scent detection: A new approach to detect invasive freshwater fish
… of its handler and assessed water samples from aquaria containing either no fish scent (non-target, n = 3), goldfish (Carassius auratus) scent (non-target, n = 5) or carp (target, n = 9) scent. The goldfish samples and six of the target samples were presented to the dog at a standard fish …

Spawning and parental care in the pink convict variety of Cichlasoma nigrofasciatum (Gunther)
… study was conducted in two parts.In Part 1 three aquaria were set up, each containing a pair of sexually mature pink convicts. Twelve different pairs were observed over a period of 120 days. Pre-spawning and post-spawning activities were noted. These were recorded in a pictograph form developed by …

CBK Bacteriophage Genome Annotation and Organization
… been isolated from local ponds, streams and the aquaria of fish stores. About three-fourths of these phages belonged to the B3 morphotype with phage CbK being the best studied. As no B3 phage genome sequences are currently available in the Genbank, we decided to determine the nucleotide sequence …

Growth and Metamorphosis of the Ringed Salamander
… Cannibalism was observed in the field and aquaria, but was not seen in dissected specimens. Major food items consisted of copepods, cladocerans and dipteran larvae. Adult coloration was completed within two months after transformation.

Field and laboratory studies suggest that recruitment of the invasive common carp is controlled by native fish in Stable Lakes of the Upper Mississippi Basin.
… placed on artificial vegetation in 70 liter aquaria that contained a bluegill sunfish or no fish, and counted twice daily until hatching. We found that the survival to hatching of carp eggs in aquaria decreased from 74% to 15% in the presence of bluegill sunfish (p-value < 0.001). In our …

The importance of bluegill feeding behavior within an automated biological monitoring system for industrial wastes
… decreased over time. A complete redesign of the aquaria was accomplished (Westlake et al. unpublished) to provide a means of long term automated feeding. An approximate maintenance ration level was determined (0.5% body wt). The response to food was a flurry of activity at the time of feeding, …
