Two neuronal chromoproteins (red-haemoprotein and yellow-carotenoprotein) initiate changes in ciliary activity on the gill of Mytilus. Photic, electrical and chemical stimulation of these chromoproteins correlate with fluctuations in ionic (calcium and iron) deposits in gill bulk tissue samples. Microspectrophotometric measurements of chromoprotein spectral band patterns reveal two or three abs...

The objectives of the study were to determine the physiological and toxicological effects of chronic cadmium exposure on juvenile rainbow trout in soft water. Particular attention focused on acclimation, on comparison to an earlier hard water study, and on whether a gill surface binding model, originally developed in dilute soft water, could be applied in this water quality to fish chronically ...

Background: Fish have been at high risk of atrazine toxicity. Comparative atrazine toxicity on the tissues of Clarias gariepinus is scanty. Therefore, acute and chronic effects of atrazine on some biochemical parameters in Clarias gariepinus were investigated in this study. Methods: Atrazine toxicity was determined by assessing the responses of glucose, protein, alanine aminotransferase (ALT...

Personal care products (PCPs) are among the most commonly detected compounds in surface water. PCPs have used large amount of metal and metal oxide nanoparticles (NPs). In the present study an attempt was made to study the bioaccumulation and biochemical constituents changes in gill tissues of a freshwater fish labeo rohita exposed to metal and metal oxide nanoparticles in domestic wastewater c...

The fresh water fish Rasbora daniconius were exposed to two sublethal concentration of sugar factory effluent for 4 weeks studied. The concentration were record 1/5(2.2%) and 1/10(1.1%) of the 96 hrs LC 5O values of sugar factory effluent. The gills of R. daniconius showed the curling and degeneration and breaking of epithelium cells of the secondary gill lamellae, destruction of blood cells, b...

The gill withdrawal reflex of the marine mollusk, Ap&u californica, shows habituation and sensitization, two simple forms of learning. In order to extend the cellular studies on synaptic plasticity underlying the changes in the reflex behavior, and to explore further the development of synaptic plasticity during synapse formation, we have sought to establish the neural circuit of the gill withd...

Microhabitat preference of the monogenean Discocotyle sagittata (Leuckart, 1842) was determined in late spring and late autumn in rainbow trout, Oncorhynchus mykiss (Walbaum), reared in the Isle of Man, U.K. Discocotyle sagittata exhibits a preference for attachment to anterior gill arches: 29% of all worms occurred on gill arch I, 28% on II, 25% on III and 18% on IV. This distribution pattern ...
