pond aquaculture is the most significant fish production method in central europe, approximately 70% of the total fish production is originated from traditional fish ponds in this region, which is a resource-saving, ecologically sustainable production method. however, the growth of this sector is not expected because of the low production capacity of valuable fish species and the relatively hig...

this study was conducted to determine the location of dna segment with homology to the rat conserved genomic dna in human chromosomes. the labeled rat genomic dna was hybridized with normal human (male) metaphases. the study of 74 metaphases after fluorescence in situ hybridization showed 371 twin-spot signals on human chromosomes. statistical analysis indicated that the specific accumulation o...

A new species of catshark (Carcharhiniformes, Scyliorhinidae), Scyliorhinus ugoi sp. nov., is described from off Northeastern and Southeastern Brazil. The new species is closest to the Scyliorhinus haeckelii/besnardi group and S. hesperius but differs in background coloration, head width, sexual maturity, and in cranial and body proportions.

Advances in RNA fluorescence in situ hybridization (RNA FISH) have allowed practitioners to detect individual RNA molecules in single cells via fluorescence microscopy, enabling highly accurate and sensitive quantification of gene expression. However, current methods typically employ hybridization times on the order of 2-16 hours, limiting its potential in applications like rapid diagnostics. W...

objectives: the presence of e.coli in fish intended for human consumption may constitute a potential danger, not only in causing disease, but also because of the possible transfer of antibiotic resistance from aquatic bacteria to those infecting humans. the objective of this study was to develop an improved pcr method based on species – specific 16 s rrna gene primers (fes, res) for detection o...

Fish reproduction, recruitment, growth and mortality normally measured using fish length method for identifying the fish species population. Normally researchers in Malaysia buy the fish and measured length of fish one by one using simple fish measuring board made out of hardwood or acrylic plastic. This current method took longest time and very costly. In this paper, the researcher used differ...
