Abstract

Lingula sp. is one of the genera of the Brachiopoda phylum that lives in the intertidal zone or areas that are affected by tides. The purpose of this study was to determine the population structure of Lingula sp. through the approach of population structure, density, distribution patterns, length and weight relationship and with physical and chemical parameters in the waters of Alue Naga, Syiah Kuala District, Banda Aceh City. The method used in this research is a purposive random sampling method. The results show that the growth pattern of Lingula sp. is classified as negative allometric at three research sites in Alue Naga waters, based on the value of b 3. The density of Lingula sp. was the highest at site 1 with a total of 17.7 ind/m2. While the density of Lingula sp. was the lowest at site 3 with a total of 9.7 ind/m2. The distribution of Lingula sp. at the three sites were uniform, with morisita index (Id) values of 0.352, 0.257, and 0.208 for sites 1, 2, and 3 respectively. In addition, the environmental factors of the three research sites in Alue Naga waters are within the normal limits of life for Lingula sp.Keywords: Alue NagaLingula sp. Population structure

Highlights

Syiah Kuala District is located at ° 36'17 ".02 North Latitude and 95 ° 21'36" .93 East Longitude (BPS Kota Banda Aceh, 2013)
One of the species that can be found in this District is Lingula sp. which is a member of the Brachiopoda phylum that lives in the waters of Alue Naga, Syiah Kuala District, Banda Aceh City
The high density at site 1 is due to the condition of the substrate at this site, which is suitable for Lingula sp. growth

Summary

Introduction

Syiah Kuala District is located at ° 36'17 ".02 North Latitude and 95 ° 21'36" .93 East Longitude (BPS Kota Banda Aceh, 2013). Syiah Kuala District is located at ° 36'17 ".02. East Longitude (BPS Kota Banda Aceh, 2013). One of the species that can be found in this District is Lingula sp. Which is a member of the Brachiopoda phylum that lives in the waters of Alue Naga, Syiah Kuala District, Banda Aceh City. Phylum Brachiopoda are marine animals with hard shells on both their upper and lower surfaces, where one shell is larger than the other (Bitner, 2009; Carlson, 2016; Harper et al, 2017). According to Jackson et al (1971) and Jain (2017), Lingula sp. Is one of the species of Phylum Brachiopoda that lives in the intertidal zone and is called a living fossil According to Jackson et al (1971) and Jain (2017), Lingula sp. is one of the species of Phylum Brachiopoda that lives in the intertidal zone and is called a living fossil
