Two Ca current components of the receptor current in the electroreceptors of the marine catfish Plotosus
In the isolated sensory epithelium of the Plotosus electroreceptor, the receptor current has been dissected into inward Ca current, ICa, and superimposed outward transient of Ca-gated K current, IK(Ca). In control saline (170 mM/liter Na), with IK(Ca) abolished by K blockers, ICa declined in two successive exponential phases with voltage-dependent time constants. Double-pulse experiments reveal...
متن کاملReceptor Ca current and Ca-gated K current in tonic electroreceptors of the marine catfish Plotosus
The tonic electroreceptors of the marine catfish Plotosus consist of a cluster of ampullae of sensory epithelia, each of which is an isolated receptor unit that is attached to the distant skin with only a long duct. The single-cell layered sensory epithelium has pear-shaped receptor cells interspersed with thin processes of supporting cells. The apical border of the receptor cells is joined to ...
متن کاملOsteology and myology of the cephalic region and pectoral girdle of Plotosus lineatus, with comments on Plotosidae (Teleostei: Siluriformes) autapomorphies
From comparisons of the cephalic and pectoral girdle structures of Plotosus lineatus with those of other plotosid as well as non-plotosid siluriforms, plotosid catfishes can be defined by at least six autapomorphies. These are: (1) the absence of the ventral division of the muscle arrector dorsalis; (2) the double articulation between the neurocranium and the anterior part of the suspensorium; ...
متن کاملGrowth performance and some haematological parameters of ornamental striped catfish (Pangasianodon hypophthalmus) fed on dietary nucleotide
The effects of dietary nucleotide (NT) on growth performance and some haematological parameters of striped catfish (Pangasianodon hypophthalmus) were investigated. Different levels of the NT (0, 0.25, 0.5, 0.75, 1%) in the diet were used for 10 weeks starting on the fish weighted (1.52 ± 0.11 g). The results showed that NT supplementations did not improve final weight, weight gain, food conserv...
متن کاملExploring the climate change concerns of striped catfish producers in the Mekong Delta, Vietnam
This study investigated the perceptions on and adaptations to climate change impacts of 235 pangasius farmers in the Mekong Delta, Vietnam. Data were collected using semi-structured household surveys in six provinces, from three regions along the Mekong river branches. A Chi-Square test was used to determine the association between variables, and a logit regression model was employed to identif...
