Studies on Some of the Fish Catching Gears in Barak and Katakhal Drainage in Barak Valley Region of Assam
Page no 103-107
In the present study, approaches had been made to study the various fishing gears that are being operated in River Barak and in Katakhal basin. An attempt had been made to document the traditional methods carried out for fishing in those areas, which revealed a total of 10 different types of fishing devices in the form of traps, nets and hooks. The efficacies of the gears were also being studied and it was found that the Gill net, Lift net and Cast net were most efficacious in those two areas.

Metabolic syndrome (MetS) is increasing globally. However, there is paucity of information on its association with obesity amongst young adults in Nigeria. This study was designed to investigate the prevalence of obesity, metabolic syndrome and the different BMI-metabolic risk sub-phenotypes in a young adult Nigerian population. A total of 200 young adult Nigerians (92 males; 108 females) took part in the study. Blood pressure and anthropometric readings were taken following standard protocols and body mass index was determined. Fasting blood sample was collected and biochemical assays were done using standard protocols. Obesity and metabolic syndrome were defined by the World Health Organization and modified National Cholesterol Education Program Adult Treatment Panel III criteria, respectively. BMI-metabolic-risk sub-phenotypes were defined by the presence or absence of the metabolic syndrome within the 3 BMI groups. Obesity was found in 10.88% (5.40% males; 15.80% females) of the study population. Metabolic syndrome was found in 23.80% (27.58% males; 20.58% females) of the population while hyperglycemia (41.26%) and hypertension (36.50%) were the most common metabolic abnormalities. Amongst the overweight and obese population, 80.00% and 60.00% respectively had healthy metabolic profiles while 23.68% of the normal weight participants were metabolically unhealthy. The different BMI-metabolic-risk sub-phenotypes occurred at rates of 20.00%–80.00% within the BMI groups. The prevalence of metabolic syndrome and BMI-metabolic-risk sub-phenotypes in this young adult Nigerian population is high. These findings underscore the need for an urgent public health action in order to forestall the possibility of a looming public health crisis.

The objective of this study was to analyze genotypic and phenotypic variability, heritability and genetic advance for grain yield and different quantitative characters using five short duration temperate maize inbred lines in a 5x5 diallel cross. High genetic advance together with high heritability for grain yield, plant height and grains per row revealed the influence of additive gene effect in determining these characters. High heritability with low genetic advance for days to 50% tasseling, days to 50% silking and cob length indicated the influence of dominant and epistatic genes for these attributes. However correlation studies showed grain yield had negative correlation with days to 50% tasseling and days to 50% silking, while positive significant correlation with plant height. Whereas positive and highly significant correlation was found with cob length, number of rows per cob and number of grains per row revealing that these are the major yield contributing traits and can help in improving maize grain yield.

The study was conducted to assess the production and economics of mono sex male tilapia (Oreochromis niloticus) reared in nine seasonal small ponds at Patuakhali Science and Technology University research farm for a period of three months during March to May 2019.The experiment was designed in three treatments (T) each with three replications. The ponds were drained, limed and fertilized with organic and inorganic fertilizers during preparation. The stocking density was 37050 fish/ha in all three treatments. After stocking the fish ponds were fertilized weekly with cowdung, urea and TSP. Supplementary feed was not given in T1, but rice bran and mustard oilcake were given in T2 and commercial pellet feed in T3. Some water quality parameters were monitored at regular intervals and they were found within acceptable range for pond aquaculture. The survival rates were high (> 96%) in all treatments. Significantly highest production (5494.10 kg/ha in three months) was found in T3 followed by T2 (2392.23 kg/ha/3months) and T1 (1048.93 kg/ha/3 months). Similarly, significantly highest net return (Tk. 206274.64/ha with benefit cost ratio of 2.01) was found in T3 followed by T2 (Tk.33100.47/ha with benefit cost ratio of 1.24) and T1 (Tk. 8254.74/ha with benefit cost ratio of 1.11).
