Developmental plasticity of cardiorespiratory physiology in response to chronic hypoxia is poorly understood in larval fishes, especially larval air-breathing fishes, which eventually in their development can at least partially "escape" hypoxia through air breathing. Whether the development air breathing makes these larval fishes less or more developmentally plastic than strictly water breathin...

Healthy specimens of Colisa fasciatus exposed to sub lethal concentration of hexavalent chromium (4.8 mg/L) for 15 days revealed no significant alterations in any testicular architecture during its different phases. However, 30 days exposure revealed distarded shape of lobule and lobular wall, scattered interstitial leydig cells during preparatory phase of testicular cycle where as during spawn...

We evaluated attraction of cerambycid beetle species to blends of known cerambycid pheromones to determine whether such blends could be used as effective trap lures for detecting and monitoring multiple species simultaneously. Pheromone-baited traps captured 1,358 cerambycid beetles of which 1,101 (81.1%) belonged to three species in the subfamily Cerambycinae: Neoclytus acuminatus (F.), Neocly...

Pethiyagoda et al. (2012) made available the genus-group name Dravidia (type species Cirrhinus fasciatus Jerdon, 1849: 305) for the ‘Puntius fasciatus’ group of fishes endemic to the peninsula of India. We were unaware at the time this paper was written (2010) that this name had shortly before been preoccupied by Dravidia Lehrer, 2010, in Diptera: Sarcophagidae. As such, a replacement name for ...

Segmentation in long germband insects such as Drosophila occurs essentially simultaneously across the entire body. A cascade of segmentation genes patterns the embryo along its anterior-posterior axis via subdivision of the blastoderm. This is in contrast to short and intermediate germband modes of segmentation where the anterior segments are formed during the blastoderm stage and the remaining...

Trichopodus, the genus of dwarf gourami fish, is oldest in Osphronemidae family, with six valid species, three which are found Sumatra. In this study, status, distribution, and morphometrics Trichopodus leerii, T. pectoralis, trichopterus from Sumatra were observed analyzed. Although these species can be distinguished based on phenotypic characteristics, it still possible to misidentify them sm...

Aeromonas spp infections are probably the most common bacterial disease diagnosed in cultured warm water fish. In the present study, six strains of Aeromonas spp bacteria were isolated from the gourami (Colisa lalia) by 16S rDNA sequencing analyses that are pathogenic to freshwater fish. Among them, three were under Aeromonas veronii species, two were Aeromonas sp ATCC and one was Aeromonas hyd...
