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

Exploited resources of major perches in India

The present paper reviews the studies on the exploited resources of mqjor perches from, the Indian seas. Major perches consist of fairly large sized fishes belonging to families Serranidae, Lutjanidae and Lethrinidae, popularly known as rock cods,snappers and pigface breams respectively. They form 17% of the total perch catch. The average annual production of major perches in the country during 1990-98 is estimated as 23,800t. The highest landing of major perches is from the state ofTamilnadu (49.5%), followed by Kerala (19.74%). They inhabit the rocky and coralline grounds of/" the south west and south east coasts and the Wadge Bank and also in the rocky grounds off Gujarat and Maharashtra . Along the south west and south east coasts, the peak fishing season is from December to April. This resource could be exploited more efficiently by hooks and lines as well as the traps rather than trawl nets, as the grounds are often not trawlable

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 (<100μm), 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

Gastrointestinal Bleeding in Patients With Acute Respiratory Distress Syndrome: A National Database Analysis.

Background:The goal of our study was to determine the impact of gastrointestinal bleeding (GIB) on in-hospital outcomes among acute respiratory distress syndrome (ARDS) patients, and subsequently determine the potential risk factors for the development of GIB. Methods:ARDS patients with and without GIB were identified using the National Inpatient Sample (2002 - 2012). Linear regression analysis was used to assess impact of GIB on in-hospital mortality, length of stay and total charges. Univariate logistic regression was used to determine associated odds ratios (OR) for causes of ARDS and common comorbid conditions. Results:We identified 149,190 ARDS patients. The incidence of GIB was the highest among patients \u3e 60 years (P \u3c 0.001). GIB was associated with longer hospitalization days (7.3 days versus 11.9 days, P \u3c 0.001), higher mortality (11% versus 27%, P \u3c 0.001) and greater economic burden ($82,812 versus$45,951, P \u3c 0.001). GIB was common in cirrhosis (OR: 8.3), peptic ulcer disease (OR: 3.7), coagulopathy disorders (OR: 3.003), thrombocytopenia (OR: 2.6), anemia (OR: 2.5) and atrial fibrillation (OR: 1.5). ARDS secondary to aspiration pneumonia (OR: 2.0), pancreatitis (OR: 2.0), sepsis (OR: 1.6) and community acquired pneumonia (OR: 0.8) was more likely to have GIB. Conclusion:Our study demonstrates that GIB in ARDS patients is associated with significant increased mortality, hospitalization and health care cost

Marine cage farming of Asian seabass under participatory mode - A success story

Karwar Research Centre of ICAR-CMFRI in association with the Directorate of fisheries, Govt. of Goa identified Polem village ( 14° 54' 21.12" N ; 74° 04' 32.20" E) in south Goa for the cage culture demonstration under the proejct 'National Innovations on Climate Resilient Agriculture (NICRA)'. Awareness programmes were conducted for the fishermen communities in the village regarding the present status of marine fisheries resources of India and future prospects
