Unusual occurrence of large size oilsardine (Sardinella longiceps) at Karwar, Uttar Kannada coast of Karnataka
The oilsardine, Sardinella longiceps
(Valenciennes, 1847), is a major pelagic fishery
resource of Malabar and Konkan coast. At Karwar,
the fishing season for oilsardine is from August-May
and the peak season is from October to March. During
the current year, after the ban period, the oilsardine
fishery by the purseseine boats started from the first
of August, 2011
Vibration Analysis of Silencer Based on FEM and FFT Analyser
Silencer was considered with and without modifying in order to reduce the vibration. Design and modeling have been done with specifying different material properties. Finite Element Method was used for the modeling and simulations. The harmonic analysis has been performed by using ANSYS 18.0. The natural frequency and working frequency are the very important parameters to study the resonance. It is mandatory to avoid this resonating condition. These frequencies are distinguished with the help of ANSYS 18.0
Bacterial Flora of Water and Rotifers in Outdoor Mass Culture Tanks Fed with Different Microalagal Diets
Investigations were carried out on the bacterial flora of water and the quality of rotifers in outdoor mass culture tanks.
Brachionus plicatilis and B. rotundiformis were cultured in 10 numbers of 1 tonne tanks and the physico-chemical parameters and
microbial loads of water, and total bacterial and Vibrio loads of microalgae and rotifers, during the period 2014-15, were studied. The
study revealed a significant variation of the ammonia levels and total bacterial loads with different diets (P < 0.05). A positive
correlation was observed between the total bacterial loads of algal concentrations and loads of rotifers, but no correlation was
observed between Vibrio loads of water and rotifers. The prevalence of Vibrio loads of rotifers was low in tanks fed with
Nannochloropsis oculata and maximum Vibrio loads were recorded in Chaetoceros calcitrans fed rotifers. The Vibrio loads
significantly varied with days of culture and also with the algal diets. A positive correlation was observed between the total Vibrio
loads of water and rotifers
Seasonal and annual variations in fish and macro-crustacean fauna in the shore seine fishery of Karwar, Karnataka
Karwar coast of Karnataka is known for sandy beaches, and these beaches apart from providing the aesthetic beauty, are supporting traditional fishermen of the coast for finding their livelihood avenues. Traditionally the beaches of Karwar is known for shore-seine operations, known as rampani fishery. Rampani nets were made of coir ropes and the nets were operated from October to March, exclusively targeting mackerel and sardines

Standardization of culture aspects of Apocyclops cmfri sp. nov. a native cyclopoid copepod
Copepods are considered as ideal larval feed,
due to their smaller size (<100╬╝m), high protein and
favourable fatty acid profiles. There are three types
of copepods viz., harpacticoid, calanoid and
cyclopoid, which can be cultured on a large scale
under controlled conditions as live feed for the
initial stages of fish and shellfish larvae. Karwar
Research Centre of ICAR- CMFRI made a significant
contribution in standardizing the protocols for the
culture of a new cyclopoid copepod
Quiescent H2 Emission From Pre-Main Sequence Stars in Chamaeleon I
We report the discovery of quiescent emission from molecular hydrogen gas
located in the circumstellar disks of six pre-main sequence stars, including
two weak-line T Tauri stars (TTS), and one Herbig AeBe star, in the Chamaeleon
I star forming region. For two of these stars, we also place upper limits on
the 2->1 S(1)/1->0 S(1) line ratios of 0.4 and 0.5. Of the 11 pre-main sequence
sources now known to be sources of quiescent near-infrared hydrogen emission,
four possess transitional disks, which suggests that detectable levels of H
emission and the presence of inner disk holes are correlated. These H
detections demonstrate that these inner holes are not completely devoid of gas,
in agreement with the presence of observable accretion signatures for all four
of these stars and the recent detections of [Ne II] emission from three of
them. The overlap in [Ne II] and H detections hints at a possible
correlation between these two features and suggests a shared excitation
mechanism of high energy photons. Our models, combined with the kinematic
information from the H lines, locate the bulk of the emitting gas at a few
tens of AU from the stars. We also find a correlation between H detections
and those targets which possess the largest H equivalent widths,
suggesting a link between accretion activity and quiescent H emission. We
conclude that quiescent H emission from relatively hot gas within the disks
of TTS is most likely related to on-going accretion activity, the production of
UV photons and/or X-rays, and the evolutionary status of the dust grain
populations in the inner disks.Comment: 12 pages, emulateapj, Accepted by Ap
Is there a need to review the syndromic case management of vaginal discharge due to candida in the Indian scenario?
Background: Vulvovaginal candidiasis (VVC) affects approximately 75% of women once in lifetime. National AIDS Control Organization has recommended Kit-2/Green (tablet secnidazole 2 gm OD stat and capsule fluconazole 150 mg OD stat) for syndromic case management (SCM) of patients with vaginal discharge since 2007. Patients are frequently revisiting the STI centre with recurrent VVC. The purpose of the study was to determine the effectiveness of fluconazole and other azoles in vulvovaginitis.
Methods: Vaginal swabs from 188 patients attending regional STI centre, at Government Medical College, Nagpur between October 2020 to June 2022 were processed. A total of 128 conventionally confirmed isolates of Candida species were tested on RPMI 1640 medium for susceptibility to azoles by E test. An MIC of тЙе8 ╬╝g/ml for fluconazole and тЙе1 ╬╝g/ml for itraconazole, ketoconazole and voriconazole was interpreted as resistance as per CLSI M-60.
Results: Candida species isolated were Candida albicans, C. glabrata, C. tropicalis, C. parapsilosis, C. dubliniensis and C. krusei. Candida species resistant to fluconazole, itraconazole, ketoconazole and voriconazole were 22 (17.18%), 53 (41.40%), 19 (14.84%), and 3 (2.34%) respectively. C. glabrata was most resistant while C. parapsilosis was least resistant. Voriconazole was most effective.
Conclusions: Extensive use of fluconazole in syndromic case management of vaginal discharge could be the probable reason for 17.18% resistance to fluconazole. Withdrawal of fluconazole and replacement with another antifungal azole in SCM of vaginal discharge may prevent recurrent VVC and perhaps lead to emergence of fluconazole sensitive candida
