Parasitic diseases are harmful and limiting factors in breeding and rearing ornamental fish industry. In this study, 400 apparently healthy ornamental fishes from five species (each species 80 specimens) including: Goldfish (Carassius auratus), guppy (Poecilia reticulate), angelfish (Pterophyllum scalare), discus (Symphsodon discus) and sailfin molli...

Dopamine release can regulate striatal acetylcholine efflux in vivo through at least two receptor mechanisms: (1) direct inhibition by dopamine D2 receptors on the cholinergic neurons, and (2) excitation initiated by dopamine D1 receptors. The neuroanatomical locus of the latter population of D1 receptors and the pathway(s) involved in the expression of their influence are controversial issues....

The paiche, Arapaima gigas represents a socio-economically important species in the Peruvian Amazon, and actually an intensive production for human consumption has emerged during the last years. Therefore, more studies are required in fish farming development, especially concerning populations of parasites that affect fish production yields. Eighty specimens of paiche collected between Septembe...

Previous reports from this laboratory have described an ability of iontophoretically applied dopamine to attenuate the inhibitory effects of iontophoresed GABA on neurons of the substantia nigra pars reticulata. This finding raised the question of whether endogenous dopamine, released from dendrites of neighboring pars compacta dopamine neurons, might act as a neuromodulator which diminishes th...

Alicodoxa rasnitsynigen. et sp. n. (Dictyopharinae: Orthopagini) is described based on a nymph from Rovno amber; it also occurs in Baltic amber. A small additional wax plate dorsal to the large wax plate of abdominal tergites VI-VIII is first reported in this and other genera of Dictyopharidae. A lectotype is designated for Pseudophana reticulata Germar & Berendt, 1856 transferred to Protepipte...

Although habitat loss and fragmentation threaten species throughout the world and are a major threat to biodiversity, it is apparent that some species are at greater risk of extinction in fragmented landscapes than others. Identification of these species and the characteristics that make them sensitive to habitat fragmentation has important implications for conservation management. Here, we pre...

This study evaluated the sensitivity of male and female guppies (Poecilia reticulata) to ammonia. LC50-96h for males, females combined sexes P. reticulata was 37.33, 48.34, 42.45 mg/L total ammonia or 1.03, 1.34, 1.17 un-ionized The mortality at concentration 40 differed between with higher in males. These results have implications production systems, since recommendations toxicity reference va...

Camellia reticulata, which is native to Southwest China, is famous for its ornamental flowers and high-quality seed oil. However, the lack of genomic information for this species has largely hampered our understanding of its key pathways related to oil production, photoperiodic flowering process and pigment biosynthesis. Here, we first sequenced and characterized the transcriptome of a diploid ...

The purpose of present review is to enlighten the present and future prospective on importance of medicinal plants on fish diseases. Now a day, the parasitic outbreak acts as an important limiting factor for fish culture. The infection of Trichodina parasites and Aeromonas hydrophila bacterium has lead to great economic loss for fish culture business. These fast antibiotics from plants are freq...
