Abstract

This research was conducted in June 2013 at Riau River Estuary inTanjungpinang City Riau Islands Province. This research aimed to find out themacrozoobenthos community structure and its relationship to seagrass vegetation.The method on the research was survey method. The existence of macrozoobenthosin this area showed the dynamic symbiosis among seagrass and marine organisms.The results also showed seagrass ecosystem had the high potential to be managed andused by communities and also increasing the fisheries productivity on coastal area.Species composition of macrozoobenthos in the area consisted of 8 species, i.e.Strombus sp, Cerithidea quadrata, Pina bicolor, Anadara sp, Anadara inflata,Atactodea striata, Asteroidea sp and Diadema sitosum. Two species of seagrassvegetation were found in this area, those were Enhalus acoroides, and Halophilaovalis. T-test analysis showed that the average of macrozoobenthos abundance oneach station differed unsignificantly (p>0,05). The regression analysis showed thatrelationship among seagrass vegetation diversity and macrozoobenthos abundancewas at r=0,35.Keywords: Riau River, Macrozoobenthos, Seagrass, Symbiont.

Abstract

ABSTRACTThe research was conducted on September to October 2014. The study aims were to determine the abundance, size distribution and distribution pattern of mangrove snail (T. telescopium) in the Darul Aman Coastal Bengkalis Regency. The method used was a survey method. Samples of snail population and sediment were collected by a single visit during low tide. Location of study was divided into 3 stations. Station I have grow rare mangrove, residential community and coastal abrasion, station II have dense and closely mangrove, station III have close with river estuary, rarely struck high tide because higher dan mangrove grow rarely than. The sample analysis carried out in Marine Biologi Laboratory of Fishery and Marine Science Faculty of Riau University.The results of the study show that the highest abundance of snail was at the station III (2,05 ind/m2) and the lowest was at the station I (0,6 ind/m2). The most dominant of size distribution is 81 – 90 mm. Distribution pattern in this area is uniform with Id between 0,88 – 0,98.Keywords: Telescopium telescopium. abundance. distribution.

Abstract

Seagrasses are plants adapted to live fully in the marine environment. Seagrass plays an important role in coastal areas due to critical habitat for many kinds of marine animals such as fish, molluscs, crustaceans, echinoderms. The research was conducted inJanuary 2015 inBeruk Island Waters in order to know the different of seagrass distribution and density in northern and southern partsof Beruk Island. The method used was line transect and applyingsix stations, namely stations I, II and III in the southern part of Beruk Island and stations IV, V and VI in the northern area of Beruk Island. The results obtained II seagrass species, i.e. Enhalus acoroides and Halophila ovalis.The pattern of distribution of seagrass at southern of Beruk Island was randomized and E. acoroideswas found as the most dominant species. However,the distribution  in northern of Beruk Island was cluster at station IV and V and randomized at station VI with the dominant species wasH. ovalis. The highest E. acoroides density was found in southern of Beruk Island at station II with the total density of 80 individuals/m2.The highest H. ovalis density in northern partof Beruk Island was at station V with the total density of40 individuals/m2.

Abstract

This study was conducted in July 2015 with the aim to observe the macrozoobenthospopulation and organic matter content in the sediment. The samples were collected from HurunBay in Lampung Province with using survey method. Samples were analyzed in the Laboratoryof Water Quality BBPPL Lampung and Chemistry Laboratory, Faculty of Fisheries and MarineSciences University of Riau. The study showed that the organic content in the sediment between22.88 - 54.91%, while the abundance of macrozoobenthos was between 20.29 - 66.67 ind / m2.Macrozoobenthos identified in Hurun Bay 8 species, 3 classes and 2 phylua. From the phylum ofMollusca there were Gastropod i.e. which had 5 species and from the classes of bivalves thestudy also found two species. From the phylum annelid there was one class, Polychaeta and onespecies, i.e. Nereis sp. The relationship between macrozoobenthos and organic content wasexpressed with the equation of Y = 9,411 + 0,6268X that the relationship of organic matter withmacrozoobenthos abundance was weak.Keywords: Lampung, sediment, organic, makrozoobenthos

Abstract

The use of probiotic is one of alternatives to solve disease problem in aquaculture. This research aimed to examine tolerance of three lactic acid bacteria (KP1, KP2, and KP3) isolated from kakap putih (Lates calcarifer) toward pH and bile salt at different consentration. The bacterial isolates were enriched on MRS agar medium. Tolerance to pH was conducted in MRS broth at pH 3, 5 and 8. While, tolerance to bile salt were performed on MRS agar at consentration of 0, 0,1, 0,2, 0,3, and 0,4 %. Isolate KP3 at pH and incubated for 48 hours showed the highest tolerance, but the highest tolerance to bile salt was indicated by isolated KP2 at bile salt consentration of 0,3 %.Keyword: Tolerance, probiotic, Kakap Putih, pH, Bile Salt.
