The objective of this research is to collect fishery based household livelihood vulnerability database, to know government efforts in reducing the vulnerability and to maintain the sustainability of fisherman's livelihoods based on terubuk. The research method is conducted qualitatively by involving informants directly or indirectly with fishing activities and fishery business terubuk. The results showed that the change of livelihood of fisherman fishery-based fishermen was caused by environmental change either from ecological asphek or from social culture asfek. Being a fisherman is a derivative work of the ancestors, the sources of vulnerability that occurs not only from natural capital (fish terubuk) but also socially, economically, and politically, the vulnerabilities of fishery-based fishery-based households are initially shaky. This vulnerability is a seasonal trend and is a habit for fishermen.

The study aimed to determine the effect of formulated feed from different vegetable sources onto growth of gouramy fingerling (Osphronemus gouramy). The method used a non factorial completely randomized design with five treatments and three replications, namely A: commercial feed (control), B: formulated feed of Moringa, C: formulated feed Gliricidia, D: formulated feed ofCentella asiatica and E: formulated feed of three vegetable mixture. The results showed that formulated feed from different vegetable sources gave highly significant effect on growth of length (1,025± 0,126 cm in average) and weight1,133 ± 0,212 gram in average), feed conversion ratio (6,96±0,32 in average)and the response of fish to feed (25,61±0,65 minutes), which was Fcount > F table. The highest value on growth and feed conversion ratio was obtained in treatment B, whereas, the best response of fish to formulated feedwas obtained in treatment A (commercial feed). Furthemore, formulated feed also provided survival rate of gouramy (Osphronemus gouramy) relatively well.

Looking for alternative material from other resource to substitution of flour in feed of fish have done in early time. This research was conducted on June - August 2016. Aimed of ths study was to determine the amount of fermented flour from Morinda citrifolia L in the feed which affect the growth, feed efficiency, feed digestibility and protein retention in tambaqui (Colossoma macropomum). This research used a completely randomized design (CRD) with one factor, 5 treatments and 3 replications. The treatment with substitution of soybean flour (SF) with fermented Morinda citrifolia L leaf flour (MF) were Controls (100% SF: 0% MF), P1 (90% SF: 10% MF), P2 (85% SF : 15% MF), P3 (80% SF : 20% MF), P4 (75% SF : 25% MF), contain of protein in the feed about 30%. Results this study showed that the best result was treatment P3 (80: 20%)with a specific growth rate of 3.03% / day, feed efficiency rate of 30.6%, 78.86% of feed digestibility and protein retention 24.99%.

This research was conducted since September until November 2008 at theWater Quality Management and Paracyties and Desease of Fish LaboratoryFaculty of Fishery and Marine Science Riau University. The aims of this researchwas to identify the damage of gill tissue structure red tilapia (Oreochromisniloticus). This research using experimental method and use completed randomdesign 1 factor with 4 treatments and 3 replications. This research using red tilapiathe measure of 8-10 cm, weight 30-40 gram from the hatchery in Pekanbaru.Result of the research show the toxicant giving effect on gill structure changes ofred tillapia fish. Fish of treatment experience of the change of structure of gillnetwork, especially happened by the nekrosis, proliferasi cells, a few moltenlamella, haemorhage and there are worm, and also secondary lamella.Concentration of toxicant hence smaller footage and apart between secondarylamella of red tillapia fish. On the contrary, excelsior of concentration of toxicant,hence wide progressively secondary lamella of gill red tillapia fish. Result of theexperiments indicated that toxicant of the AlK(SO4)212H2O concentrations havean effect on the gills tissue structure of red tilapia. Concentrations of toxicantincrease caused the gills tissue structure came to be better.

The research was conducted in March 2011 at the laboratory of FishProcessing Technology, Food Chemistry and Food Microbiology, Faculty ofFisheries and Marine Science University of Riau. Aimed of this study was todetermine the characteristics of fermented tilapia with different carbohydratesources. About 5 kg fish weighting 100 gr each was taken from a fish market inPekanbaru. Two groups of fish was fermented repeatedly using roasted rice andfermented bamboo shoot. The fish was fermented at room temperature for 7 days.Quality characteristics of the fermented fish was evaluated for sensory atributes(appearance, flavor, odor, and texture), chemical value ( pH, moisture, NPN,lactic acid), and lactic acid bacteria count. The fish which was fermented withroasted rice was characterized by appearance (attractive, clean, yellowish color),flavor (sour and salty, typical fermentation), odor (acid/alcohol, less fresh, typicalfermentation) and texture (dense, compact, chewy). Chemical value: pH (5,91),moisture (53,6%), NPN (0,12 ml/gr), and lactic acid (1,23 ml/gr), lactic acidbacteria count (5,44 x 10 6 ). Fish fermented with fermented bamboo shoot wascharacterized by appearance (attractive, less clean, opaque), flavor (sour and salty,less savory, not typical fermentation), odor (acids and less alcohol, typicalfermentation) and texture (elastic, compact, chewy). Chemical value: pH (5,38),moisture (59,79%), NPN (0,19 %), and lactic acid (1,71 %), lactic acid bacteriacount (8,167 x 10 6 colony/gr).Keywords: fermented tilapia, roasted rice, and bamboo shoots

Tiger Grouper is one of the sea water fish commodities that is quite popular with the community and has a high economic value. The problem faced by farmers is the attack of Vibriosis, one of which is caused by the Vibrio alginolyticus bacteria. The use of synthetic antibiotics has been widely used but has many adverse effects, so it needs new alternatives for the treatment of Vibriosis disease. One of them is by using the extract of lifelong leaf extract. Life-sustaining plants (Gynura procumbens) contain secondary metabolites such as flavonoids, tannins, and antibacterial saponins. This study aims to determine the best dosage of lifelong leaf extract for the treatment of Vibriosis disease in tiger grouper. The study was conducted in two stages, namely in vitro and in vivo. Before the fish were treated with feed that had been given a sambung deca leaf extract, the fish were challenged using Vibrio alginolyticus with a density of 108 CFU / mL as much as 0.1 mL / head and then fed with treatment and maintained for 21 days. The results of the in vitro study showed that the life of sambung leaf extract at a dose of 700 ppm had a broad inhibitory effect on V. alginolyticus, which amounted to 10.47 mm compared to other treatments. Whereas when continued for in vivo testing, a dose of 350 ppm in general has been applied for the treatment of attacks of Vibrio alginolyticus in tiger grouper.
