The sensory, nutritional and microbial quality of collected dried samples were evaluated following organoleptic quality index, standard AOAC and aerobic plate count methods, respectively. Organoleptically no significant difference found between the samples from market and drying center. The highest moisture content value was obtained in Bombay duck (29.78%) from the market and lowest value in Chinese pomfret (20.06%) from drying center. The highest and lowest protein content was in Chinese pomfret (60.73%) and Bombay duck (47.9%) from drying center and market, respectively. The lipid and ash content varied from 2.85% to 7.20% and 13.98% to 19.57% for all the dried fish species collected from both sites. Microbiologically, higher aerobic plate count (APC), total E. coli count (TEC) and total Salmonella count (TSC) were found in Chinese pomfret at 1.96×106 CFU/g, 3.98×105 CFU/g and 1.62×105 CFU/g from market and lowest count found in Bombay duck at 5.05×105, 2.22×105 and 0.81×105 from drying center, respectively. In ribbon fish no Salmonella sp. was found. Based on the sensory and nutritional quality the study conclude that among three species and two sites studied, the dried Bombay duck from the fish drying center had better quality characteristics than the counter parts. However, higher microbial load especially pathogenic TSC and TEC suggests to improve hygiene and sanitary practices, better market distribution and storage facilities need to be followed by the producers for safe and quality dried fishery products.","PeriodicalId":213044,"journal":{"name":"Bangladesh Journal of Fisheries","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125481282","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

After 48 hours, 40 ml eutrophicated water having 34.75 x105 to 36.0 x 105 cells/ml of phytoplankton were provided in each aquarium. Initial concentration ofphytoplankton was 14400±360.55, 13900±360.55 and 14133± 404.14 cells/ml, whereas the finalconcentrations were 10300±100.00, 8300±200.00 and 10333±57.73 cells/ml in T1, T2 and T3, respectively.The reduction rate was consistently lower in T2 when compared to other treatments. Mussels of T2 (pH 8.0)exhibited significantly higher filtration rate (p<0.05) over T1 (pH 7.5) and T3 (pH 8.5) at all sampling times.The minimum filtration rate 58.03±32.79 ml/mussel/h was found in T3 after 1 h exposure, whereas thehighest filtration rate 110.94 ± 21.68 ml/mussel/h was obtained in T2 after 2 h exposure.

Resultsshowed relatively better growth performance of D. magna in mixed feed trials compared to single or ‘nofeed’ trial. Among three feed trials, Tyg incurred the lowest cost compared to others and the cost toproduction ratio was 7.8.

The moisture,protein, lipid, and ash content and pH value in mustard hilsa decreased compared to those obtained for freshfish. On the other hand, TVB-N and peroxide values increased compared to the values found in fresh fish. Atrefrigeration temperature and frozen temperature moisture and ash contents increased but protein and lipidcontent decreased gradually throughout the storage period. pH value of the mustard hilsa reduced from 7.22to 6.01 and 6.59 at refrigeration and frozen temperatures, respectively. The TVB-N value and peroxide valueincreased progressively throughout the storage period irrespective of storage temperatures. Rate of changes indifferent parameters of mustard hilsa was slower in vacuum sealed packs than non-sealed and sealed packs.The aerobic plate count of bacteria was increased in refrigeration temperature but the load of microbes wasreduced at frozen temperatures. The result of sensory quality change showed that, irrespective of storagetemperature and packing condition the scores of sensory quality parameters decreased with the progress ofstorage time though the decreasing rate was slower at frozen temperature. The study concluded that, atrefrigeration temperature mustard hilsa might remain in acceptable condition up to 60 days and at frozentemperature for about 180 days in vacuum sealed pack.

Monthly pama croaker samples were collected from the industrialfisheries in the Bay of Bengal. The length-length relationship was constructed algebraically in the form ofy=a+bx. Relationships between SL and TL for male, female and unsexed populations were separatelyestablished. Sex ratio between male and female did not deviate from the parity (?2 test; p>0.05). The SL andTL ranges of male were 7.2-22 cm and 9.5-28 cm respectively, and the SL and TL ranges of female were6.8-20 cm and 8.4-25.7 cm respectively. Intercept and slope varied monthly in all length-length relationshipsregardless of gender categories. The generalized SL-TL relationships of male, female and unsexedpopulations were TL=1.214SL+0.761(R=0.989), TL=1.212SL-0.770(R=0.990) and TL=1.203SL+0.904(R=0.987) respectively. The correlation coefficients of both monthly and generalized regression analyses ofall sex types were very high (R?0.852) which explained that the relationships between the two lengthdimensions were strongly correlated. The growth corollary appeared both as isometric and allometric formonthly populations. Allometric growth was apparent in July, August and September in all gender types,while isometric growth was deduced in other months.
