Visual responding in Macrobrachium rosenbergii (de man)

Physiology & Behavior, 1979
Abstract In the present study the capacity of Macrobrachium rosenbergii (de man) to respond to a food reinforced visual stimulus was tested. Four female Macrobrachia showed a significant reduction in approach latency, over 12 successive days with four trials each, to a stimulus consisting of a disc with horizontal stripes placed to the outside wall ...

The Effect Of Salinity On The Crowth Of Macrobrachium rosenbergii

Proceedings of the annual meeting - World Mariculture Society, 1976
ABSTRACTJuvenile Macrobrachium rosenbergii were grown in the four salinity treatments; freshwater, 2 ppt, 8.5 ppt and 15 ppt. Best growth occurred in the lower salinity (2 ppt), while growth was impaired at the highest salinity (15 ppt). Implications of the results on the hypothesis that growth in aquatic organisms may be enhanced in isosmotic media ...

On the role of algae in larviculture of Macrobrachium rosenbergii

Aquaculture, 1976
Abstract The possible roles of algae (i.e. “green water”) in facilitating Macrobrachium rosenbergii larviculture have been investigated. Larvae were incubated with 14 C uniformly labeled Tetraselmis sp. and Phaeodactylum sp. No counts were incorporated by the larvae indicating that negligible quantities of algal cell material are ingested ...

Clearance of Macrobrachium rosenbergii nodavirus (MrNV) and extra small virus (XSV) and immunological changes in experimentally injected Macrobrachium rosenbergii

Fish & Shellfish Immunology, 2010
Macrobrachium rosenbergii was experimentally challenged with Macrobrachium rosenbergii nodavirus (MrNV) and extra small virus (XSV) to study the clearance of these viruses and consequent changes in various immunological parameters. The healthy animals were injected MrNV and XSV intramuscularly and various organ samples such as gill tissue, head soft ...

Responses of freshwater prawn,Macrobrachium rosenbergii, to chemical attractants

Journal of Chemical Ecology, 1987
Chemoreception in the adults of the freshwater prawnMacrobrachium rosenbergii was investigated under controlled laboratory conditions, using behavioral assays. Tests were carried out on groups, as well as on individuals, all at their intermolt stages of the molt cycle, and prestarved for three to four days.

Transcriptomics-based analysis of Macrobrachium rosenbergii growth retardation

Comparative Biochemistry and Physiology Part D: Genomics and Proteomics
Macrobrachium rosenbergii is an economically important crustacean in many parts of the world, but in recent years, growth retardation has become an increasingly serious issue. While the underlying causes remain unclear, this has inevitably impacted on aquaculture and production outputs.

Rearing Macrobrachium rosenbergii larvae in Fiji

Aquaculture, 1984
Abstract Rearing Macrobrachium rosenbergii larvae to post-larvae has been accomplished using simple techniques. Live Artemia nauplii, ground kai meat ( Batissa violacea ) and tuna ( Thunnus albacores ) were used as food. About 16 300 post-larvae were produced in 13 trials.

Effects of Cu2+ on alkaline phosphatase from Macrobrachium rosenbergii

International Journal of Biological Macromolecules, 2018
To gain insight into the effect of Cu2+ on the activity and structure of alkaline phosphatase (ALP) from Macrobrachium rosenbergii, the enzyme was purified using ammonium sulfate fractionation, Sephacryl S-200, and DEAE anion exchange chromatography.

Oriented spermatozoa in the spermatophore of the palaemonid shrimp, Macrobrachium rosenbergii

Tissue and Cell, 1987
Estimates of the degree of orientation of spermatozoa within spermatophores of the freshwater shrimp, Macrobrachium rosenbergii, were made using electron micrographs of ultrathin sections cut transverse and parallel to the longitudinal axis of the spermatophores.
