Dynamics of Priacanthus hamrur (Forsskal) exploited off Saurashtra coast

Bull’s eye landings off Saurashtra reached a peak of 3813 tons in 1999 with a catch rate of 4.3 kg per haul. The group is represented by a single species, Priacanthus hamrur (Forsskal). Gut content analysis revealed P. hamrur to be a carnivorous fish with a preference for pelagic crustaceans and fishes. Spawning females were encountered from March to December and the length at first maturity of female P. hamrur was 198 mm. Recruitment to the fishery takes place with two peaks annually - one in January-February and a minor one in October-November. A common length-weight relationship for both sexes was obtained with a = 3.481x105 and b = 2.83498. The von Bertalanffy growth equation was derived as Lt = 360.35 [1-e-0.56(t+ 0.1013)] and the length attained by the fish at the end of 1 to 4 years were estimated as 165, 249, 296 and 324 mm. The length growth performance index was obtained as !’ = 4.86 and the longevity, tmax was estimated as 4.44 years. The mortality co-efficient Z, M and F were 2.35, 1.14 and 1.21, respectively and exploitation rate, E was 0.51. Stock assessment studies reveal that the present average annual catch can be increased by 764 t to reach the MSY of 4996 tons

Climate change and vulnerability of Coastal Villages in Tamil Nadu

Climate change is mainly the effect of human activities such as burning of fossil fuels, land conversion, deforestation, infrastructure development, industrial processes and from agriculture processes

Unusual catch of flapnose ray in ring seine

An estimated 130 ring seiners are employed exclusively to exploit small pelagic resources such as sardines and mackerels along south Cuddalore coast. Occassionally large mobulid rays are also landed in stray numbers as by-catch in the ringseine landings at Cuddalore Fisheries Harbour. There has been no incidence of elasmobranch landings in large quantities by ring seines in this region. However on 15.07.2017, an unusually high landing of an estimated 1. 3 tonne (t) of the flapnose ray Rhinoptera javanica was observed

OBESITY AS RISK FACTOR IN TYPE-2 DIABETES MELLITUS IN MIDDLE AGED WOMEN

Background: Type 2 diabetes is a common chronic disease resulting from a complex inheritance-environment interaction along with other risk factors such as obesity and sedentary lifestyle. Type 2 diabetes and its complications constitute a major worldwide public health problem, affecting almost all populations in both developed and developing countries like India with high rates of diabetes-related morbidity and mortality. Method: 110 women volunteers of age 35 to 55 years depending upon body mass index, were divided into five groups. Control (BMI; 25 kg / m2), Group I (BMI 25-29.9 kg / m2), Group II (BMI 30-34.9 kg / m2), Group III (BMI 35-39.9 kg / m2), Group IV (BMI > 40 kg / m2) were selected as subjects.  Their Body Mass Index, Waist - Hip circumference ratio (W/H), Fasting blood sugar (FBS), lipid profile: serum triglycerides (TG), serum total cholesterol and HDL, VLDL cholesterol were assessed. Result: There is a close association between obesity and type 2 diabetes. The mean values of FBS, HDL, TG & VLDL are significantly higher in group I compared to controls. The mean values of W/H ratio, FBS, HDL, TG & VLDL are higher in group II, III and IV compared to controls. Conclusion: In the middle aged women obesity is the major factor which increases the risk for diabetes. Obesity plays a role by altering homeostasis of the body; it does this by bringing about the changes in the various parameters studied.KEYWORDS:  Middle aged women; Obesity; Type-2 diabetes mellitus

ClimFish NICRA Newsletter Vol.1

Govt. of India has accorded high priority on research and development to cope with climate change in agricultural sector. The Prime Minister’s National Action Plan has identified agriculture as one of eight national missions. The project so far has benefitted several stakeholders across the nation. National Innovations on Climate Resilient Agriculture (NICRA) is a network project of Indian Council of Agricultural Research (ICAR) aimed at enhancing resilience of Indian agriculture to climate change

Study of effects of combined spinal epidural analgesia on the course of labour and feto maternal outcome in comparison with the parturients receiving no analgesia

Background: The study was aimed to evaluate the effects of combined spinal epidural analgesia on the duration and outcome of labour in nulliparous parturients in comparison with parturients not receiving any analgesia.Methods: It is a prospective clinical study. The present study was carried out in the labour ward, KIMS Hubli. Nulliparous parturients in early active labour were divided into two groups.  CSE group (n=40) and non CSE group. In present study CSE was performed with intrathecal 1.25mg of levobupivacaine with   25mcg fentanyl initially and this was followed by epidural boluses of 10ml of 0.0625% Levobupivacaine with 2mcg/ml fentanyl through the epidural catheter whenever the patients’ pain score is more than 4.Results: Mean duration of active labour was 139+/-41.2min in CSE group and 251.1+/-57.9 min in non CSE group. The rate of cervical dilatation was 2.63+/-0.66cm/hr. in CSE group as compared to 1.45+/-0.38cm/hr in non CSE group. The duration of second stage of labour was similar in both groups. The spontaneous vaginal deliveries was77.5% in CSE group as compared to 79.5% in non CSE group. Assisted vaginal deliveries were 15% in combined spinal epidural analgesia group compared to 10.3% in non CSE group which was statistically insignificant. LSCS was 7.5% in control CSE group compared to 10.3% in non CSE group. Maternal satisfaction was excellent in majority of parturients in CSE group. The perinatal outcome was not affected in CSE group. The incidence of complications were very minimal in present study.Conclusions: Authors concluded that combined spinal epidural analgesia provides safe and excellent analgesia with no significant increase in the caesarean section and instrumental delivery rates. In addition, CSE decreases the duration of first stage of labour with no effect on perinatal outcome

On the unusual landing of juvenile black pomfret at Veraval and Mangrol landing centre of Gujrat

Pomfrets form an Important component in the fishery off Mangrol and Veraval. They are landed by trawl nets and monofilament gill nets. The silver pomfret Pampas argenteus Is locally called "Vichhuda" and the black pomfret, Formio niger is called "Halva". The former dominates the pomfret fishery with peak landings in the monsoon and post monsoon period. The black pomfret does not show any regular pattern of landing
