A review of the current status of freshwater prawn farming globally, with comments on the statistical information available is provided in this symposium keynote paper. A brief overview of the research on freshwater prawn farming that has been published in international journals since 2000 is also provided. Finally, some research needs are listed and some scenarios for future expansion are expl...
An experiment was conducted to determine the impact of fish and prawn culture on some physicochemical parameters of water, weeds, benthos, and rice yield under simultaneous method for a period of 5 months from July to November 2007. The experiment was comprised of five individual treatments having three replicates for each. The treatments were: rice combined with fish and regular urea fertiliza...
A heated debate has recently emerged between tiger farmers and conservationists about the potential consequences of lifting the ban on trade in farmed tiger products in China. This debate has caused unfounded speculation about the extent of the potential market for tiger products. To fill this knowledge gap, we surveyed 1880 residents from a total of six Chinese cities to understand Urban Chine...
In laboratory conditions, the analysis of total toxicity some technogenically disturbed soils Belgorod region was carried out using bioassays: Daphnia magna Straus , green algae Scenedesmus quadricauda (Tiger) and Lepidium sativum L. As a result experiments, degree tested established. The conducted studies confirm high information content when three bioassays for soil toxicity.
The size-frequency distribution of the commercial catch is often used as the basis of fisheries stock assessments (Pauly and Morgan, 1987; Gulland and Rosenberg, 1992) because most dynamic processes of populations (growth, survival, recruitment) are reflected in changes in this distribution. The data are generally collected, often at great expense, by sampling the catch at landing sites and mar...
We investigated the phylogenetic diversity and metabolic capabilities of members of the phylum Planctomycetes in the anaerobic, sulfide-saturated sediments of a mesophilic spring (Zodletone Spring) in southwestern Oklahoma. Culture-independent analyses of 16S rRNA gene sequences generated using Planctomycetes-biased primer pairs suggested that an extremely diverse community of Planctomycetes is...
A cytosolic manganese superoxide dismutase gene (Es-cMnSOD) was cloned from the Chinese mitten crab Eriocheir sinensis, using reverse transcription-polymerase chain reaction and the rapid amplification of cDNA ends. The open reading frame of Es-cMnSOD is 867 bp in length and encodes a 288-amino acid protein without a signal peptide. The calculated molecular mass of the translated protein of Es-...
Serotonin (5-HT) mediates a number of diverse physiological functions in crustaceans by interacting with various 5-HT receptor subtypes. A putative 5-HT receptor cloned from the ovary of the black tiger prawn (Penaeus monodon) consisted of 2291 nucleotides, encoding a putative 5-HT(1Pem) receptor protein of 591 amino acids. Transient expression of 5-HT(1Pem) in HEK293 cells demonstrated a satur...
The production and trade of ornamental fish is one of the most profitable sectors of aquaculture and is growing and developing in Asia and around the world. Tiger barb is an interesting fish that has long been in Iranian aquariums and has attracted the attention of enthusiasts. The barbs are a subfamily (Cyprinidae) of freshwater fishes native to Southeast Asia. The natural geographical range o...
