this study examined the effects of two bacteria (bacillu subtilis bp6 and lactobacillus plantarum lp3) on survival, growth and digestive tract microflora of achanthopagrus latus larvae with different delivery methods. for each bacterium was considered three treatments with different delivery methods. in first treatment, fish larvae were exposed to each bacterium through feeding them with bacter...

The problem of invasive species has reignited interest in biological control as a management tool. Classical biological control involves deliberate release of exotic natural enemies into new environments in an attempt to limit the density of an invasive species. Persistent, sustained limitation of invasive species by coevolved natural enemies is a seductive concept. Evidence now suggests, howev...

A taxonomic review of the Sebastes pachycephalus complex established the existence of two valid species, S. pachycephalus and S. nudus. Similarities between them include: cranium armed dorsally with robust preocular, supraocular, postocular, and parietal spines; interorbital space concave; lower jaw lacking scales, shorter than upper jaw; thickened rays in ventral half of pectoral fin; dorsal f...

Stylet-Oil was effective in reducing incidence of tobacco etch virus (TEV) (Genus: Potyvirus, Family: Potyviridae) in ‘Scotch Bonnet’ pepper (Capsicum chinense Jacquin) plots by about 24% and delaying its spread by 7 days. A backpack mist blower (low volume) was used to apply JMS Stylet-Oil at pressures of about 1000 kPa to pepper plants weekly, from transplant until the end of the crop. Seedli...

The agarose-coupled triazine dye Procion Red HE-3B has been demonstrated to be applicable as an affinity gel for the purification of five diverse hydrogenases, namely the soluble, NAD-specific and the membrane-bound hydrogenase of Alcaligenes eutrophus, the membrane-bound hydrogenase of the N2-fixing Alcaligenes latus, the reversible H2-evolving and the unidirectional H2-oxidizing hydrogenase o...

The marine nematodes usually comprise free-living species, although a few are parasitic. However, several cases of free-living nematodes found accidentally in the digestive tract of certain vertebrates, especially fishes, have sometimes been recorded and categorized as pseudoparasites. In the present work, two species of marine fishes, the rhomboid crappie, Diapterus rhombeus, and the silvered ...
