In order to study the role of the kidney in fish osmoregulation, freshwater acclimatized juvenile spottedscat (Scatophagus argus L.) were subjected to four different salinities and observed for histomorphometricchanges of the kidney at 1, 2, 10 and 15 days post transfer time points. The overall morphological changesdisplayed by fish kidney included significant decrease in the density of collect...

Spotted scat ( Scatophagus argus ) is an important mariculture fish that of great economic significance in East and Southeast Asia. To date, there are no studies on ovary development regulation S. . Herein, the transcriptome profiles at different stages were constructed, genes pathways potentially involved secondary follicle growth identified. A total 25,426 detected by sequencing mRNAs from li...

Neuropeptide Y (Npy) is an intricate neuropeptide regulating numerous physiological processes. It a highly conserved peptide known to improve feed intake in many vertebrates, including fishes. To enlighten the mechanism of Npy spotted scat control, we cloned and identified cDNA sequence. We further examined its expression some tissues explored effects at different time frames (hours days). Here...

Marine fish are generally unable or have low ability for the biosynthesis of long-chain polyunsaturated fatty acids (LC-PUFA) from C18 PUFA precursors, with some notable exceptions including the herbivorous marine teleost Siganus canaliculatus in which such a capability was recently demonstrated. To determine whether this is a unique feature of S. canaliculatus or whether it is common to the he...

Organotin compounds have been found different application in industries, agricultures and pharmacological sciences via their various physical and biological specifications. One of the most important applications of these compounds, especially tributyltin TBT is in marine antifouling paints and coatings. Concern about the accumulation of tributyltin compounds on fish and shellfish and the advers...
