On a whale shark Rhiniodon typus landed at Malpe, Udupi district, Karnataka

A whale shark Rliiniodon typus Smith of 610 cm total length and weighing 4 tonnes was accidentally caught by a purse seiner on 26.12.2000 at a depth of 20 m off Malpe, about 10 km from Malpe fishing harbour

New Fish meal plant at Karwar to process oil sardine

Karnataka recorded an appreciable catch of 1,00,179 t of oil sardine in 2007. The boom in oil sardine landings has lead to the establishment of a new fish meal plant at Baithkol landing centre of Karwar which became functional in March, 2008 (Fig. 1). The Karnataka Fisheries Development Board has leased out the fish meal plant to a private company, Sai Annapoorna Bio-Protein Private Ltd. The products manufactured by the fish meal plant are fish oil and fish meal powder. They supply fish oil to CP Aquamarine which exports the fish oil to south-east Asian countries such as Vietnam and Thailand. The fish meal powder is used as prawn feed and it is procured and marketed by CP Aquamarine. The company procures fish from Mangalore to Goa from boat owners and agents. The average supply of fish is 200 t/day. The company processes only oil sardine (Sardinella longiceps) for the manufacture of fish meal and fish oil

Migrant labourers in the marine fisheries sector

It is now recognised that migration is an integral part of the survival strategies of the poor; especially where local economics offer limited livelihood alternatives. Intervention strategies should, therefore, be directed at reducing the vulnerability of migrants, not at reducing migration itself. Migration has become a key facet of today’s world. Migrants living outside their country of birth are 191 million

Comparative study (II): On the longevity of pupa and adult moths in selected few bivoltine purelines of silkworm Bombyx mori (L) in all the seasons of the year.

A comparative study utilizing the six multivoltines, in three seasons of the year between pupal and adult moth stage of silkworm of reveals a positive significance. Pupal duration was calculated after chrysalis stage among six multivoltines clearly indicated that the duration of pupae in the pre race is lowest where as the Daizo race exhibited the longest pupal duration of 240 hours. Silkworm adult life span evaluated in three seasons in the two sexes (male moth and female moth) it is clear that race pre exhibited shortest adult life span of 84 hours in mated males and 114 hours in mated females during pre-monsoon period and Daizo race revealed prolonged adult life span 222 hours in unmated males and 242 hours in unmated females during post-monsoon period. In the present studies among the two sexes, the unmated (virgin) male and females moths exhibited the longest life span than those of mated male and female moths. The influence of three seasons on adult life span is very clear from the experiment. The effect of pre-monsoon is more conspicuous (revealing short lifespan) where as in post-monsoon season lifespan is longest both in the pupal and adult. The results obtained from the present studies clearly demonstrate that racial differences, seasonal impact and sex wise differences are important in the expression of adult longevity

An attempt for Indoor rearing of tasar silkworm Antheraea mylitta Drury on Terminalia catappa in the natural atmospheric conditions of Mysuru

The non mulberry silkworm’s tasar, eri and muga are grown in hilly forest regions of north eastern part of India where climatic conditions are favourable and they feed on various wild food plants and many of them grown in plane lands for ornamental purpose. An attempt made to grow tasar silkworm Antheraea mylitta in the natural atmospheric conditions of Mysuru during the rainy season (June-September) by using the secondary food plant Terminalia catappa, resulted in the larval life span of 30 days on an average and the effective rate of rearing of 27%.  The results were proved that the survivability ratio and the quantity and quality of the cocoons produced were found to be affected that may due to the new environmental conditions and secondary food plant provide

Risk Factors for HSV-2 Infection among Sexual Partners of HSV-2/HIV-1 Co-Infected Persons

<p>Abstract</p> <p>Background</p> <p>Herpes simplex virus type 2 (HSV-2) is the most frequent cause of genital ulcer disease worldwide and has been associated with increased risk for HIV-1 acquisition and transmission. We conducted a cross-sectional analysis of risk factors for HSV-2 infection among HIV-1 uninfected partners, whose partners were co-infected with HIV-1 and HSV-2.</p> <p>Methods</p> <p>Between November 2004 and April 2007, 3408 HIV-discordant couples, in which the HIV-1 infected partners were HSV-2 seropositive with CD4 250 cells/mm³or greater, were enrolled in an HSV-2 suppression trial to prevent HIV-1 transmission at 14 sites in 7 African countries. Clinical & behavioral data, HSV-2 and HIV-1 testing were conducted at enrolment. Univariate and multivariate Poisson regression analyses were performed separately, by gender of the HIV-1 infected partner.</p> <p>Results</p> <p>Among 3354 HIV-1 uninfected participants, 32% were female and overall 71% were HSV-2 seropositive. Among couples with female HIV-1 infected partners, HIV-1 plasma RNA [aPR 1.03; 95% CI: 0.99 to 1.06; p = 0.11] and CD4 count [aPR 1.00; 95% CI: 0.98 to 1.01; p = 0.48] in the HSV-2/HIV-1 dually infected female and circumcision in the HIV-1 uninfected male partner [aPR 0.94; 95% CI: 0.88 to 1.00; p = 0.06] were not associated with reduced risk of HSV-2 seropositivity, after adjusting for other factors.</p> <p>Conclusions</p> <p>In this cross-sectional analysis of African HIV-1 serodiscordant heterosexual couples with prevalent HSV-2 infection in the HIV-1 infected partner, HIV-1 plasma RNA and CD4 count in the dually-infected partner and male circumcision in the HIV-1 uninfected partner were not associated with HSV-2 concordance.</p> <p>Trial Registration</p> <p>ClinicalTrials.gov <a href="http://www.clinicaltrials.gov/ct2/show/NCT00194519">NCT00194519</a></p

Effect of light and media upon growth and melanin formation in Cladosporium mansoni

Cladosporium mansoni (ATC #762) was shown to grow best on trehalose although a number of other carbohydrates are good carbon sources. On the other hand, starch, lactose and inulin support growth poorly, or not at all. In certain media light induces the formation of abundant mycelium whose cells are of average size; in the dark, little or no mycelium is formed and many “giant” cells appear. The pigment of C. mansoni was extracted and shown to have properties in common with those of melanins of other fungi. Extracellular granules, resembling melanin, appear in a defined medium containing dextrine and ammonium nitrate. A comparison between the response of Cladosporium mansoni and Aureobasidium pullulans to light and carbon sources shows several points of divergence.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/43279/1/11046_2005_Article_BF02089218.pd
