The mechanism of sound reception and the hearing abilities of the prawn (Palaemon serratus) have been studied using a combination of anatomical, electron microscopic and electrophysiological approaches, revealing that P. serratus is responsive to sounds ranging in frequency from 100 to 3000 Hz. It is the first time that the Auditory Brainstem Response (ABR) recording technique has been used on ...

IT has been suggested (Huxley, 1927; Shaw, 1928) that in various animals, such as some Crustacea which show disharmonic growth, there exist growth centres correlated with the active growth of specific organs or regions. Also that the growth of neighbouring parts is correlated with the growth of the heterogonic organ. In Maia squinado (Huxley, 1927) and Inachus dorsettensis (Shaw, 1928) the grow...

Aquaculture systems may release large amounts of nutrients into the marine ecosystem that can lead to eutrophication. Many seaweed species are efficient in reducing the nutrient concentration in aquaculture waste. In this study, the agarophyte Gelidium elegans originating from Korea was investigated for bioremediation of tiger shrimp (Penaeus monodon) broodstock effluent (SBE) in a shrimp hatch...

Accumulation of cadmium in the hepatopancreas of the common prawn Palaemon serratus (Pennant) and ultrastructural changes m hepatopancreatic cells were examined after exposure to 3 cadmium concentrations (5, 25.50 ppm) for 44 h. Accumulation of cadmium Ions in 50 ppm solution was 800 % higher compared with control specimens. Absorptive and fibrillar cells (Rand F-cells) in the hepatopancreas we...

objective: boerhaavia elegans l. (nyctaginaceae) is a medicinal plant used for the treatment of kidney disorders, urinary tract disorders and blood purification in baluch tribe. the aim of present study is to evaluate the antioxidant propertyof b. elegans species for the first time. materials and methods: different parts (leaf, stem and fruit) of the plant were extracted by using various solven...

koelreuteria elegans, popularly known as “flame gold” is an ornamental tree. in vitro callus induction and regeneration from various explants (eaf segments and cotyledonary leaf) were studied on modified ms medium. the highest callus induction rate (80%) and multiplication was obtained in 2 mg/l 2,4-d from leaf segments. calli transferred in 1.5 mg/l bap resulted in efficient shoot regeneration...
