Abstract

This research was conducted in February until March 2017 at Pandan Island island pandan area tourist Park Pieh Island. The purpose of this study was to investigate the characteristics of the nesting habitat of the hawksbill turtle (Chelonia mydas). The method used in this research is the survey method, with measuring directly on the habitat of hawksbill turtle covering the slope of the beach, texture of sediments, within the nest of tides, the temperature of the nest, fecundity, and the type of vegetation and predators in the nesting habitat. The results showed that the nesting habitat characteristics vary between nest with each other. Nesting beach ramps ranged 2,75-4,60º with medium sand sediment texture to coarse sand. Temperatures nest ranging between 27-31ºC. The dominant vegetation in the area is a nesting plant pandan laut (Pandanus tectorius) whereas the dominant predator was biawak (Varanus salvator).

Abstract

This study was conducted in September 2021, around the coastal of Concong luar village Indragiri Hilir Regency with the aim to find out the abundance, distribution, and morphometrics of blood shell (Anadara granosa). The method used survey methods, in which blood shell sampling and aquatic substrates, as well as measurements of environmental parameters, were conducted in the field and in the laboratory. Determination of sampling location by purposive sampling is based on the character of the environment in the location of the research. Based on the results of research that has been obtained an abundance value at the station 1 = 4,8 Ind/m2, station 2 = 8,7 Ind/m2, and station 3 = 3 Ind/m2. The pattern of blood shell levy in the waters of Concong Luar Village stations 1 and 2 is clustered, while station 3 is evenly distributed. Furthermore, the results of measurement of the width of the highest blood shells are 16 - 30 mm in 70 individuals, followed by size >31 mm of 43 individuals, the lowest measurement result is <15 mm in 27 individuals, and the highest measurement of the length of the blood shells 16 – 30 mm of 77 ind, followed by a size >31 mm of 42 ind, and the lowest measurement result is <15 mm of 29 ind.

Abstract

This research was carried out in January 2021 in the Intertidal Zone of Sambungo Village, Silaut District, Pesisir Selatan Regency, West Sumatra Province. The purpose of this study was to determine the size variation of the bivalve, the distribution pattern of the bivalve, the effect of the type of sediment fraction on the size, and the distribution of the bivalve in the intertidal zone. The method used in this research is a survey method which is carried out by direct observation and sampling in the field. Bivalve samples obtained were identified at the Marine Biology Laboratory and Sediment Fraction Analysis was carried out at the Chemical Analysis Laboratory, Faculty of Fisheries and Marine, Universitas Riau. Based on the results of the study, the highest number of bivalves was at station 1 as many as 11 individuals. The distribution pattern of macrozoobenthos in the intertidal zone of Sambungo Village ranges from 3.86 to 5.07 with the highest morisita index value being at station 1. The highest percentage of sediment fraction is 96.53% in the lower zone and the highest organic matter content is at station 1 of the lower zone. with a total percentage of 6.65%. Based on the criteria for the morisita index at station 1, station 2, and station 3 with an Id>1 value, it can be concluded that the distribution of Bivalvia in the intertidal zone in Sambungo Village is clustered
