To assess the growth and culture potentials of Indian white prawn Penaeus indicus, locally knownas Chaka Chingri, a preliminary trial was conducted for a period of 145 days in earthen ponds. The postlarvae were collected from Sundarbans coast and stocked in 3 ponds of 0.056 ha each with the stockingdensity at 30, 40 and 54 m-2in T1,T2 and T3 treatments respectively. Commercial pelleted feed with 36%protein was fed. Production and physico-chemical parameters were recorded and analyzed according tostandard methods. After 145 days of rearing, obtained average final weight was 22.18±6.71g, 25.25±3.11gand 29.25±2.88g; with the estimated yield of 1197 kg/ha, 3030 kg/ha, and 3632 kg/ha, survival was 18%,30% and 23% in T1, T2 and T3 treatments respectively. Results and findings of the present study suggestedthat P. indicus might be potential mariculture candidate in the coastal areas of Bangladesh.

In Bangladesh, shrimp post-larvae (PL) are mainly produced in hatcheries. From 2000s shrimp PL are reared in nurseries containing small earthen ponds by relatively poor people for a few days before stocking into the shrimp farms. This study assesses the physical and chemical parameters of five such nurseries at Satkhira district, Bangladesh using scientific instruments and semi-structured questionnaire. The nursing process involved stocking of PL (4151.8 ± 1581.35 PL/m2) in small earthen ponds (<18m2 area/pond) and raring for up to 10 days with feeding. Most of the physico-chemical parameters were within the suitable range recommended for shrimp culture. The survival rate of PL ranged from 80% to 90%. The nursing system was profitable as the average Benefit-Cost Ratio (BCR) was 1.19. The establishment and operation of these nurseries do not require any expensive equipment or complex technology and can be run by less educated and poor people. However, constraints like lack of credit and continuous water supply are hindering the scaling up of these nurseries in size and number. By providing means to overcome the constraints these nurseries can be an excellent income generating source for the poor entrepreneurs as well as contribute in increasing shrimp production in Bangladesh.

The article presents the results of studies of osmolality and pH of 0,9 % sodium chloride of various manufacturers. To obtain data on the pH value, the data used in the passports are used, and the indicators of its osmolality are de- termined using laboratory tests. 0,9 % sodium chloride from different manufacturers has different pH and osmolality. Knowing the actual values of physico-chemical parameters can increase the accuracy of the results of future clinical studies, which compare the pharmacokinetics and pharmacodynamics of modern plasma-substituting solutions and a solution of 0,9 % sodium chloride.
