Abstract

ABSTRACT This study aimed to determine the consumer acceptance on fermented rebon shrimp (cincalok) and the amount of salt appropriate to stimulate the growth of lactic acid bacteria in it.The method used in this research was the experimental method and composed as Completely Randomized Design (CRD).The experiment was conducting byproducingcincalokadded with different amount of salt (15%, 20%, and 25%, each based on the rebon shrimp weight). The parameters used were organoleptic evaluation (appearance, aroma, taste and texture) and the amount oftotal lactic acid bacteria (LAB). The results showed that the different amounts of salt added was significantly affecting to theconsumer acceptance on rebonshrimpcincalok. The highest consumer acceptance of cincalok was produced by addition of 25% salt, showing by the highest value of appearance (7.6), aroma (7.4), flavor (6.4), and texture (6.9).The different amount of salt also affected significantly to the LAB growth, showing by the highest amount of total LAB 17,55 x 103cfu/g in the cincalok produced by addition of 25% salt.It could be concluded that the best treatment was addition of 25% salt to produce the most preferred cincalok. The organoleptic characteristics was shown by the attractive appearance with bright pink color; the rather sour aroma typical of cincalok; a combined taste of slightly acid and salty typical of cincalok; and slightly dense waterytexture.            Key words:Acetes erythraeus, Consumer acceptance, Lactic Acid Bacteria, Salt

Abstract

AbstractSibam River is inhabit by small sized prawns. Scientific information of those organism, however,  is almost none. To understand the types of prawns present that area, a research has been conducted from April to May 2017. There were 3 sampling areas, in the upstream (St I), the middle area (St II), an in the downstream (St III). Prawns sampling were conducted once/week for a month period, using a scoop net (mesh size 0.5 cm). Morphometrical and meristical characteristics of the prawns were analyzed descriptively and te prawns sampled were identified. There were 65 palaemonids prawns captured and they were identifed  Macrobrachium. Detail identification showed that they were Macrobrachium mammilodactylus (15 specimens, 9 males and 6 females) and Macrobrachium heterorhynchos (50 specimens, 6 males and 44 females). M. mammilodactylus charactererized by schapocherite length that is shorter than rostrum length, 7-18 teeth in the dorsal and 2-6 teeth in the ventral of rostrum, all segments except fingers with abundant short mammiliform protective setae. M. heterorhynchos charactererized by carapace and glabrous abdomen, without microspinules. In males, rostrum one-third distal extending beyond scaphocerite, 8-9 teeth in the dorsal and 4 teeth in the ventral. In female, rostrum just reaching end of schapocerite, 8 teeth in the dorsal and 5 teeth in the ventral.Keywords: Sibam River, freshwater prawns, Macrobrachium mammilodactylus, Macrobrachium heterorhynchos

Abstract

ABSTRACTOsteochilus hasselti is found in the Tarai River that has been contaminated with organic pollution and it may affects the reproductive biology of the fish. A study aims to understand the reproductive biology of O. hasselti has been conducted. The fish was sampled 3 times, once/month, from November 2017 to January 2018.  Parameters measured were sex ratio, gonad maturity level, Gonad Somatic Index (GSI), fecundity and egg diameter. Results shown that there was 29 males and 49 females (sex ratio 1:2). Male has slimmer body, brighter color than those of the female. Genital papilla of the male was white, while that of the female was red. Size at maturity level in male ranged from 95 to 170 mm SL, while that of the females was 90 to 190 mm SL. The average GSI of male ranged from 1.61 to 8.51% while that of the females was 1.02 to 11.14%. The average fecundity was 65,451 eggs/female and egg diameter was 0.10 to 1.00 mm. Based on the size of egg diameter can be concluded this fish is total spawner. Keywords: Sex ratio, gonad maturity level, gonad somatic index, fecundity, total spawner
