Abstract Objective Fish and crustacean are important sources of animal proteins and other essential nutrients required in the human diet. They are widely accepted for their high palatability, high protein content and tender flesh. In this study, proximate analyses were done for flesh of brackish water shrimp species Penaeus monodon and fresh water fish species Oreochromis niloticus .Results Percentage of protein content was high values in Penaeus monodon (9.31±0.63) compared to Oreochromis niloticus (7.85±0.79). The highest lipid content was present in Penaeus monodon (0.23±0.22%) while the lowest value was shown by Oreochromis niloticus (0.07±0.16%). Comperativily, the percentage of total carbohydrate content is the highest in Brackish water shrimp than fresh water fish Nile tilapia. The study revealed high protein content and a high fat content in the meat of Penaeus monodon . Information on the nutrient composition of Penaeus monodon is needed to encourage the processing, utilization and marketing of this commonest species of Sri Lanka. It can then be inferred that the shrimps ( Penaeus monodon ) could be employed as a supplement of protein and minerals, so as to balance human nutrition. Hence the consumption of shrimps ( Penaeus monodon ) would help as a good source of nutrients.

Observation Period

16th February 2015. Due to a number of missing tables and figures, this article (DOI: http://dx.doi.org/10.3329/jesnr.v7i1.22144) was withdrawn from Vol.7(1) and has been republished with corrections in Vol.7(2) pp.177-184 (DOI: http://dx.doi.org/10.3329/jesnr.v7i2.22228).An investigation was carried out on the fish marketing system and availability of fish species at Daulatpur fish market in Khulna over 12-months from September 2012 to August 2013. Combinations of the participatory, qualitative and quantitative methods were used for questionnaire interviews for data collection. A total of 115 species of fresh water, brackish and marine water fish and crustacean species were identified during the observation period. The number of fresh water fish species was found 60 including 14 fresh water culture species and 12 SIS whereas brackish and marine water species was found 41 and crustacean species was 14 including 5 fresh water prawn, 6 marine and brackish water shrimp and 3 crabs. During the observation period, it was found that the availability of culture fish species was higher in the market and it was 55.86% including 17% catfish, 15.65 % tilapia, 15.56 % carp fishes, 4.18% koi, 2.47% punti and 1% prawn. Catfish, carps, tilapia, snakehead, baim, shing-magur, punti, koi etc were the major abundant groups among the fresh water fish species whereas ilish and some shrimp were the abundant species of marine and brackish water fish. The highest abundance (55.86%) was found the fresh water culture fish species following to marine and brackish water species (28.01%) and fresh water capture species (16.01%). The market chain from farmers/fishermen to consumers encompassed mainly primary, secondary and retail markets involving local agents (foria and bepari) suppliers, aratdars, wholesalers and retailers. During the observation, it was found that the auctioneers get 3 to 5% commission by performing their activities. Aratdars also get 4 to 5% commission due to arrange auctioning activities and providing other facilities such as clean water supply, electricity, space, communication etc which is called aratdary. In some cases farmers have to pay market tools that locally called khazna which vary from 5 to 10% depending on amount of sales. Market structure, species quality, size and weight have an influence on the price of fish and it was found that the price of fish increases per kilogram with increasing size and it varied with species to species. Every step of intermediaries of marketing channel obtained certain amount of profit and ultimately the farmers/fishermen received an average near about 60 percent of the retail price of fish in the market.DOI: http://dx.doi.org/10.3329/jesnr.v7i2.22228 J.

Membrane Treatment

The availability of fresh water is vital for all human activities and in particular for improving living conditions, health and overall well-being. Pressure on scarce fresh water resources can be reduced by treating and reusing brackish water by advanced membrane treatment technologies. In this study, brackish water originating from effluent discharge of a local coal mine, seawater, groundwater and salt water swimming pool is treated by a laboratory-scale vacuum membrane distillation (VMD) system. VMD is an emerging technology that has the potential to become as important as conventional distillation system and aims to remove particles and dissolved impurities by evaporation and condensation techniques that mimic what occurs in nature. This study validates the mathematical modeling of the transport mechanisms used in the VMD process using data collected for different experimental situations. The response of flux rate to various process operating parameters, including pressure, temperature, flow rate and salinity concentration, is also demonstrated. This thermally driven separation process enables to remove 99.9% of total dissolved solids (TDS) from brackish water. The quality of the permeate water from all four water sources studied is of acceptable standards for potable use; however, it requires mineralization efforts before direct consumption.

Oil In Water Emulsion

ABSTRACT Orimulsion is an oil-in-water emulsion of Venezuelan bitumen. Orimulsion was found to behave predictably in salt (33°/oo NaCl) and fresh water, driven by buoyancy to rise in salt water and sink in fresh water; but behaviour in brackish water (20°/oo NaCl) was difficult to predict. Temperature has also been indicated as having an influence on Orimulsion behaviour. The current study extended experimentation down to lower temperatures, and a variety of mixing energies. This study resulted in new information on the behaviour of Orimulsion spills in salt, fresh, and brackish water with salinity values of 20 and 33 degrees at temperatures of 5 and 15 degrees Celsius. Energy was varied by adjusting the applied rotational field and measurement with thermal probes. Depletion rates and characteristics were determined by adding Orimulsion to a 300-L tank of water, taking a time series of samples, and determining the concentration of bitumen and the particle size distribution. Changes in bitumen concentration and particle size distribution as a function of time were also measured. Using these data, simple equations were developed to describe and predict the concentration of bitumen in the water column as a function of time. Similarly nomograms showing the amount of oil on the bottom and on the water surface are presented.
