Present study was conducted to evaluate nutritional values of smoked hilsa fish (Tenualosa ilisha; Hamilton, 1882) in relation to its raw condition. Smoking is one of the processes of fish preservation from ancient period of our country. The nutrients values of the hilsa from two different regions were significantly (p < 0.05) varied. The nutritional values were different before and after processing of hilsa. Riverine hilsa contains relatively more moisture (56.45 ± 0.51%) and protein (15.98 ± 0.50%) than marine hilsa. Fat (16.18 ± 0.45%) and salt (1.92 ± 0.18%) contents are higher in marine hilsa; whereas ash (8.34 ± 0.35%) content was higher in riverine hilsa. Minerals like iron (4.72 ± 0.08 mg/100 g) and calcium (481.77 ± 6.20 mg/100g) remain in large amount on marine hilsa but phosphorus (115.73 ± 4.36 mg/100 g) content remain high level in riverine hilsa. In addition, the protein (raw condition, 19.54 ± 0.47%, riverine; 17.12 ± 0.42%, marine and smoked condition, 29.64 ± 0.41%, riverine; 28.51 ± 0.51%, marine) and fat (raw condition, 16.41 ± 0.46%, riverine; 20.07 ± 0.39%, marine and smoked condition, 20.71 ± 0.47%, riverine; 23.31 ± 0.47%, marine) content were higher in abdominal region of riverine and marine hilsa both raw and smoked condition than head region (protein in raw condition, 11.21 ± 0.51%, riverine; 10.51 ± 0.53%, marine and smoked condition, 17.14 ± 0.42%, riverine; 15.69 ± 0.4%, marine; fat in raw condition, 9.04 ± 0.45%, riverine; 11.21 ± 0.51%, marine and smoked condition, 12.32 ± 0.44%, riverine; 14.56 ± 0.47%, marine) and caudal region (protein in raw condition17.21 ± 0.52%, riverine; 15.22 ± 0.66%, marine and smoked condition, 27.68 ± 0.44%, riverine; 26.73 ± 0.46%, marine; fat in raw condition, 14.05 ± 0.5%, riverine; 17.28 ± 0.47%, marine and smoked condition, 17.35 ± 0.43%, riverine; 19.18 ± 0.51%, marine).

The study revealed the status of formalin used in four commercially important fishes namely Rohu (Labeo rohita), Catla (Catla catla), Mrigal (Cirrhinus cirrhosus) and Hilsa (Tenualosa ilisha) from Sylhet and Moulvibazar district for a period of four months from April to July 2016. A total of 100 fish samples from different town and village markets were collected and analyzed instantly on the market to detect the presence of formalin by using a kit developed by Bangladesh Council of Scientific and Industrial Research (BCSIR). Among the analyzed fishes 46.7, 26.7, 20.0 and 13.3% of Rohu, Catla, Mrigal and Hilsa, respectively were found treated with formalin from Sylhet district. Similarly, formalin was also detected in 40, 20, 20 and 20% of investigated Rohu, Catla, Mrigal and Hilsa from Moulvibazar district, individually. There was no significant difference in formalin used between town and village market, whereas a significant difference in application of formalin in domestic and imported fishes except Catla has been identified. Two-third of imported Rohu (66.7%) was found formalin positive followed by Hilsa (44.4%), Mrigal (40%) and Catla (35.7%). Amongst the domestic fishes, presence of formalin was detected in 27.8, 18.8, 10.0 and 4.8% in Rohu, Catla, Mrigal and Hilsa, separately. This devastating use of formalin in food fishes should be banned through proper enactment of the existing laws of the country, as well as timely and appropriate implementation of government monitoring is mandatory to combat the unethical formalin use.

Brackishwater Pond

This study aims to estimate the wealth and stability of traditional and intensive brackishwater pond waters through biological index calculation (diversity, uniformity and dominance of plankton) in traditional and intensive brackishwater pond waters of Probolinggo Regency, East Java Province. Sampling plankton and water from the site, considered to represent the diversity of plankton and water stability of traditional and intensive brackishwater pond. Plankton was collected using a plankton net no. 25, then preserved using 1% lugol solution. Measurement of water quality variables include temperature, salinity, dissolved oxygen and pH, whereas the laboratory analyzes that Total Organic Matter (TOM), NO2, NO3, NH3, PO4, Total Suspended Solids (TSS), and Fe. Plankton identification using microscope and calculation with cell counting method. The results of analysis of plankton in intensive brackishwater pond waters are obtained as much as 23 genera consisting of 16 genera of phytoplankton were included into three classes, namely Bacillariophyceae as much as 5 genera, Cyanophyceae 3 genera, Dinophyceae and Chlorophyceae, each of the four genera, whereas zooplankton consisting of 7 genera are included into two classes, namely Crustaceae 6 genera and Rotatoria 1 genus. In traditional brackishwater pond earned as much as 13 genera consisting of 8 genera of phytoplankton were included into Bacillariophyceae 5 genera, Cyanophyceae 2 genera, and Dinophyceae 3 genera, whereas zooplankton consisting of three genera are included into class Crustaceae 2 genera and Rotatoria 1 genus. Plankton abundance in intensive brackishwater pond ranges 702 - 4269 ind./L, diversity index of 0.26 -2.38, uniformity index of 0.10 - 1.5, and dominance index of 0.02 - 0.68. In traditional brackishwater pond have an abundance of plankton range 134 - 776 ind./L, diversity index of 0.10 - 1.97, uniformity index of 0.08 - 1.0, and dominance index of 0.01 - 0.75. Traditional and intensive brackishwater pond waters condition still within the limits that can be tolerated by the culture organism. Based on the index value of biological, diversity of genus in the intensive brackishwater pond is relatively higher than traditional brackishwater pond and the community stability moderate, whereas traditional brackishwater pond unstable. On average, the uniformity of the genus in both  brackishwater ponds are relatively evenly and genus of plankton to dominate the others genus.
