Effects of lead on hepatocyte ultrastructure in Carassius carassius (L.) var. auratus
Tissue and Cell, 1991Subcellular modifications in hepatocytes of Carassius carassius var. auratus subjected to 24 hr and 48 hr sublethal acute lead (5mg.1-1) exposure were studied by electron microscopy. Cytological alterations were observed after 24 hr of treatment and became more evident after 48 hr.

A family of highly repetitive DNAs (Hi-a) in the genome from a population of the crucian carp, tentatively identified as the ginbuna (Carassius auratus langsdorfi), was isolated from the HindIII digests and characterized. The Hi-a monomer (268 or 269 bp) was AT-rich (64.9%) with internal repetitive oligomers.

Auditory stream segregation in goldfish (Carassius auratus)
Hearing Research, 1998Goldfish were classically conditioned to a mixture of two pulse trains differing in both repetition rate and the spectral profile of the pulses. Animals were then tested for generalization to single pulse trains having one or the other spectral profile presented at a variety of repetition rates.

Exploratory behaviour of goldfish Carassius auratus
Animal Behaviour, 1974Abstract The exploratory locomotor behaviour of twenty-one naive goldfish in a homogeneous open field during 20-hr periods was monitored and analysed into spatial and temporal characteristics. The fish did not randomly explore the entire field. Locomotion is organized spatially and temporally.

Mitochondria of Goldfish, Carassius auratus
Nature, 1960THE metabolism of mitochondria of poikilotherms acclimatized at different temperatures has not been studied, though such studies have been made on rats1,2. The mechanisms of adaptation to cold and warm temperatures in a poikilotherm may be different from those of a homoitherm due to the presence of a temperature-regulating centre in the latter.

Intestinal peroxisomes in the goldfish (Carassius auratus)
Comparative Biochemistry and Physiology Part A: Physiology, 19731. 1. Homogenates made from the intestinal mucosa of the goldfish (Carassius auratus) were centrifuged through linear sucrose gradients in a zonal rotor. 2. 2. The distribution of subcellular markers after rate zonal centrifugation showed the presence of distinct, slowly sedimenting particles containing catalase. 3. 3.

Avoidance of fenitrothion by goldfish (Carassius auratus)
Bulletin of Environmental Contamination and Toxicology, 1975Goldfish (Carassius auratus) avoided water containing the pesticide fenitrothion. The response was graded over the tested concentration range of 5 orders of magnitude, with a threshold around 10 mug/1, equivalent to 3.5 times 10-minus 8 M.

SDS-electrophoresis data on protein patterns of tissues of the goldfish Carassius auratus netted in winter, spring and summer and kept at different temperatures are presented. It has been ascertained that after keeping ??winter?? fish at 5??C for 2 weeks quantities of the protein 205 kD in red muscles and heart and the protein 172 kD in liver are ...
