Abstract

The purpose of this study was to determine the characteristics of nesting habitat of sea turtle in Lhoknga beach. The observation was conducted at three locations from January to March 2016. The study showed that the coastal slope average ranges 1.03 ° - 1.38 °. The average of nest temperature was 28.05 °C to 29.47 °C (inside the nest) and from 28.77 ° C to 29.95 ° C (at the surface of the nest). The width beach at high tide ranges from 20.17 m to 21.83 m and 31 m to 33.83 m at low tide. The nest humidity ranges from 20.5% -24.15%. There were six species of coastal vegetation recorded during the study, where station 1 has higher of density and diversity of the coastal vegetation. In general, Lhoknga Beach is suitable for nesting of the sea turtle. A total of 13 sea turtles (Lepidochelys olivacea) were nesting during the study, where station 1 had higher of nesting frequency.

Abstract

The objective of the present study was to evaluate the migration time of glass eels (Anguilla spp.)  in the estuary of  Lambeuso River, Aceh Jaya District, Indonesia. The survey was done in March and June 2015.  The sampling location was determined based on an initial survey during February 2015 by considering the river condition. Based on initial survey there are no glass eels were recorded during noon time, and therefore the sampling was focused at night. The sampling was done four times a month (weekly basis) for three months (12 times in total) using trap nets based on Hijri Calendar. The trap was settled up to opposite direction of tide (seaward) from 18.00 PM to 06.00 AM  and the catches glass eels were monitoring one-hour interval.  A total of 131 glass eels were sampled during the study, where the samples were only caught on first (new month) and fourth week (old month) base on Hijri Calender  during spring tide and  no glass eels were sampled during second and third weeks. It was concluded that the migration time of the glass eels (Anguilla spp.) in Lambeso Rivers is during the dark moon at the new and old month of Hijri Calendar
