Abstract

Grouper is one of the economically important fish groups in the Simeulue and Banyak Islands. However, data on the diversity of the grouper in this region is still limited. This study aimed to inventory the commercially important grouper in Simeulue and Banyak Islands. Sampling was carried out in April - September 2021 at sixteen locations around Simeulue and Banyak Islands. In total, 20 species of commercial grouper consisting of 6 genera were recorded during the study. Epinephelus was the most dominant genus with ten species, followed by Cephalopholis with four species. In addition, seventeen species (85%) were included in the Least Concern (LC), two species (10%) were categorized as Vulnerable (VU), and one species (5%) was Data Deficient (DD). This study provides a database of commercially important grouper in Simeulue and Banyak Islands that can be used to manage the fish group.

Abstract

Indonesia is recognized as one of the territories that have the highest reef fish biodiversity in the world. One of the commercially valuable fish in this area is the groupers (locally name "kerapu"). At least 76 grouper species have been reported in Indonesian waters, with three species were categorized into "vulnerable", five species "Data Deficient", and 68 species under the "Least Concern" category based on IUCN classification. The increasing exploitations rate had been reported caused the grouper stocks in Indonesia to decrease and threatened extinction. However, only limited scientific data is available regarding the grouper in Indonesia, including their identification. In most fish landing sites across Indonesia, the groupers are morphologically identified and recorded as "kerapu" to replace their scientific species names. Accurate species identification is essential in designing appropriate and sustainable management of fisheries resources. One of the tools that have been used in fish identification is DNA barcoding. In the last two decades, this molecular method has been applied to identify many fish groups globally, including grouper fish. This study reviewed the DNA barcoding approach in grouper identification in Indonesia based on the available literature.Keywords:DNA barcodingGrouperMolecular TaxonomyFisheriesIndonesia

Abstract

Barramundi (Lates calcarifer) is one of the commercial fish in Indonesia. The phenomenon of climate change due to global warming has affected the life of aquatic biota, including fish. The objectives of the present study were to determine a critical thermal maximum (CTMax) and the behavior of Barramundi (L. calcarifer) due to the increase in water temperature. The research was conducted at the Fishing Technology Laboratory, Faculty of Marine and Fisheries, Universitas Syiah Kuala in February 2021. The experiment was conducted in 10 aquariums equipped with heaters. The initial temperature of the treatment was 28oC and increased gradually every one minute by 0.2oC. The results showed that the abnormal behavior of Barramundi fingerling was started to appear at 37oC where the fish began to swim fast, then swim sideways at 38oC-39oC, hit the container wall at 39oC-40oC, jumped and weakened then dead at 40oC and 41oC. The average critical temperature of Barramundi fingerling was recorded at a temperature of 41oC within 65 minutes. Therefore, it is concluded that the Barramundi (L. calcarifer) display an abnormal behavior above the temperature of 35oC, however, they can survive up to 42oC exposure for 70 minutes.Keywords:Critical thermal maximumTemperature riseGlobal warming
