Abstract

AstractOne of the biota that lives in mangrove ecosystems is the gastropod telescopium telescopium. Telescopium telescopium has more active behavior at spring tide (high tide and low tide) than low tide (low tide and high low tide). The weight of the gonad will reach a maximum of a moment when the mangrove snail will spawn, then the weight of the gonad will decrease rapidly as long as the spawning is in progress until complete. This research was carried out in June-July 2018, sampling in the mangrove ecosystem of Ketapang Beach waters, Sungai Cingam Village, Rupat District, Bengkalis Regency, Riau Province. The samples were analyzed at the Marine Biology Laboratory of the Faculty of Fisheries and Marine Sciences, Riau University. This study aims to determine the population structure of gonad maturity index and habitat conditions of T. telescopium gastropods in Ketapang Beach waters, Sungai Cingam Village, Rupat District. The method used in this research is survey method. Measurement of water quality parameters is carried out in situ, namely temperature, and determination of sampling locations by purposive sampling, salinity and pH, type of substrate in sandy mud dominance. Water quality parameters are still supportive for the life of mangrove snails. Average density of Tcopcopium T in the mangrove forest of Sungai Cingam Village is low. There were no differences in density between the research stations but there were differences in density between the study zones. The average distribution pattern of T. telescopium is clustered. The size of T. telescopium found ranged from 38-87 mm. The main habitat of T. telescopium is in zone 2 (lowere zone).Keywords: Population structure, Telescopium telescopium, Rupat Island.

Abstract

Density and distribution population of sea urchin Diadema setosum was conducted in May 2014 at Setan Island. The research aimed to know about its density and distribution pattern. The study used survey method by applying transect and plot. The location of research was covering 3 stations. The stations were chosen base on existence of sea urchin D. setosum on coral reef (reef flat). Transect drawn from 5 m up to 15 m depth during low tide. There were there three plots with a size of 3x3 m² along the transect .The results showed that the sea urchin numbers was 332 individuals, where the density range value was 1,367 individuals/m2. The highest density was recorded at station I and the lowest density was found at station III. Morisita indeks dispersion showed that the location had a uniform distribution (Id<1), except for station III had a clumped distribution (Id>1). The highest size frequency of sea urchin D. setosum was ≤2 cm dan the lowest was 4,1-6 cm.Keywords: Setan Island,Density, Distribution,Diadema setosum

Abstract

ABSTRACT             This research was conducted in February - March 2019 in the waters of Sungaitohor Village Kepulauan Meranti Regency Riau Province. The aims of the study were to analyze the organic content in the sediment and macrozoobenthos abundance and the relationship of organic sediment with macrozoobenthos abundance. Determination of the research was purposive sampling of 4 station with 5 sampling points where the distance each sampling point was 500 meters wich were based on the initial sampling point. Makrozoobenthos in the study area consist of 10 species of 2 classes, namely class gastropod and malacostraca. The study showed that the organic content in the sediment was found between 8.57 – 26.07 %, while the abundance of macrozoobenthos was between 18.33 – 58.33 ind/m2. The relationship between macrozoobenthos and organic sediment was expressed with the equation of Y = 3.667 + 2.099X, r = 0.759, the higher content of organic sediment lead to the higher the makrozoobenthos abundance. Keywords: sediment organic, macrozoobenthos, abundance

Abstract

This study was conducted in December 2013 at Dumai river estuary. Thestudy aims were to determine the abundance distribution of mangrove snail (T.telescopium) and correlation between abundance and sediment organic content.The method used was a survey method. Samples of snail population and sedimentwere collected by a single visit during low tide. Location of study was dividedinto 3 stations. Station I located inside the conservation area, station II waslocated close to shipyard, while station III laid near by a residential community.The analysis carried out in Marine Biologi Laboratory of Riau University.The results of the study show that the highest abundance of snail was atthe station III (6,55 ind/m2) and the lowest was at the station I (1,99 ind/m2).Statistical analysis (Anova) show that there was no significant differentabundance among those stations. Regression analysis show that the relationshipbetween the abundance of T. telescopium and organic sediment content wasnegatively correlated (r = 0,453).Keywords: Telescopium telescopium, abundance, organic Sediment, Dumai Riverestuary

Abstract

ABSTRACT               Barnacle is one of the marine biota that belongs to the crustacean class and is one of the sub-classes of Wikipedia, whose life is permanently attached to hard objects submerged at sea and has properties that can damage and shorten the life of a building that it occupies. The purpose of this study was to determine the rate of sticking barnacles on wood, concrete and peralata substrates. This research was conducted from January 28 to March 10 2019 in the waters of the Purnama Coast in Dumai City. The method used is the experimental method. The results  are the highest rate of barnacle attachment found in wood is 63 ind/week, then the concrete substrate 35 ind/week and the lowest is the 18 ind/week pipe plastic substrate. The highest abundance of barnacles on wood substrates in the 6th week with a value of 25 ind/m2and the lowest abundance of barnacles was found on the paralon substrate in the 6th week with a value of 3 ind/m2. Keywords: barnacles, substrate, attachment rate, abundance, Dumai

Abstract

This research was conducted in October to December 2016 at fish seed center Pengujan, Bintan, Riau Island. The purpose of research was to determine the best concentration of Extrajoss for improving the rate of population growth of B. plicatilis in media culture. Complete Random Design (CRD) was applied as a method at this study with 4 taraf treatments that is P0 media consists of 300 mg chicken manure, 7.5 mg TSP, 6 mg Urea, 0.45 g yeast Bread/3 liters of water (control), then for further media added P1 (0.30 g Extrajoss), P2 (0.40 g Extrajoss), and P3 (0.50 g Extrajoss) with 3 replicates and observation 2 times day. The results is there’s a population growth rate differences occurring B. plicatilis after being given by Extrajoss. The highest population density is obtained at the 6th day of observation in the media of P2 11.36 ind/ml, and the lowest population contained on media P3 Of 1.00 ind/ml, while the highest average growth rate was obtained at the treatment the P2 of 2.731 ind/ml and the lowest obtained on treatment of P3 of 1.257 ind/ml.Keywords: Brachionus plicatilis, Extrajoss, BBI Pengujan
