Check list of marine fishes from Simeulue Island waters , Aceh Province , Indonesia

The objective of the present study was to inventory the marine commercial fishes in Simeulue waters, Aceh Province, Indonesia. Sampling was conducted on August 2017. The sampling was conducted in fish landing and direct sampling by using handline hooks and casting net. A total of 77 species of marine commercial fishes belong to 7 orderS, 26 families and 54 genera were recorded during the study. Serranidae was a predominant family with 14 species followed by Lutjanidae with 13 species and Carangidae 9 species.


INTRODUCTION
Aceh Province has big potency on aquatic resources for example, 70,000 inland waters, 73 main rivers, marshes and wetlands and lakes (Muchlisin, 2012).Muchlisin and Siti-Azizah (2009) recorded 114 species of freshwater fishes in Aceh waters where several species have potency for aquaculture development (Muchlisin, 2013); However, no information on the marine fishes in Aceh waters.In addition, there were two species of endemic fishes recorded in Aceh waters, namely Rasbora tawarensis dan Poropuntius tawarensis (Muchlisin et al., 2013).Previous studies showed that several species of fishes in Aceh waters have been listed in IUCN redlist, for example genus Tor (Muchlisin et al., 2015a), Anguilla (Muchlisin et al., 2017a), Epinephelus (Ramadhani et al., 2017) and Zenarchopterus (Fadhil et al., 2016).
Presently, the study on fish diversity in Aceh waters was focusing on inland waters (Muchlisin and Siti-Azizah, 2009;Rudi and Fadli, 2012;Muchlisin et al., 2013;Nasir, 2014;Muchlisin et al., 2015b), and it was very limited information on marine fishes.Simeulue Island is situated in the Indian Ocean about 115 km from the mainland Sumatra.This Island has potency in marine and freshwater fishes, for example the annual catch volume was increasing from 8,042.00 tons in 2011 to 13,966 tons in 2015 (BPS Simeulue, 2016).Several studies have been conducted in Simeulue Island waters, for example characteristic of capture fishery (Carle et al., 2014) and marketing chains of lobster businesses (Zulham and Nasution, 2016;Triyanti and Yusuf, 2015) and ichthyofaunal of Lake Lauik Tawar and Lake Laulo (Muchlisin et al., 2017b).This paper reported the marine fishes harvested from Simeulue Island waters, Aceh Province, Indonesia.

MATERIALS AND METHODS
The study was conducted on August 3 rd , 2017 in Simeulue Island (Figure 1).Fish samples were collected by direct sampling using handline hooks and casting nets.The handline hooks are used on deep ocean waters, while the casting nets are used on the coastal shallow waters.The location of the sampling was based on information from local fishermen.The coordinate of each location was recorded.Beside, the fish samples were also collected from fishermen catches in fish landings.
The representative of each species was collected and photographed prior to preserving in 10% formalin.The sampled fishes were measured for total length using the digital calipers (Mitutoyo, CD-6CS.Error = 0.01 mm), and weighed using a digital balance (Toledo, AB-204.Error= 0.01 g).The fish samples were identified based on Kottelat et al. (1993), Allen (2000), Inger dan Kong (2002), Vida dan Kotai (2006) dan Ambak et al. (2010).The data were presented in

RESULTS
A total of 77 species of marine fishes belonging to 7 orders, 26 families and 54 genera were recorded during the study (Table 1).Perciformes was a predominant order with 18 families, 44 genera and 67 species (Figure 2), where Serranidae is predominant family with 14 species followed by Lutjanidae with 13 species and Carangidae 9 species (Appendix).

DISCUSSION
A total of 77 species of commercial marine fishes from Simeulue waters were recorded in this study.Of these, 47 species are coral reefs fishes, where Serranidae and Lutjanidae are predominant (Appendix).This is probably due to the condition of the coral reefs in Simuelue Island have been recovered after more than 10 years of massive tsunami in December 2004 and March 2005.Several studies just after tsunami reported that most of the coral reefs areas in Simeulue has damaged by tsunami waves and in several parts, the coral reefs was uplifted 1.55 to 1.60 meters (Aron et al., 2010;Suyarso, 2008;Fujino et al., 2014).Fortunately, in recent years the coral reefs have been grown and recovered well, thus becoming a habitat for marine organisms, especially for fishes (Carles et al., 2014;Mutmainah et al., 2016).The previous study by Muchlisin et al. (2017b) have been successfully recorded 11 species of freshwater fishes from this region.Hence, a total of 88 species of marine and freshwater fishes were documented from Simuelue Island.
The results showed that Serranidae or common name groupers is a predominant group of fishes in Simeulue Island waters, this is the commercial important of fishes (Jaafar et al., 2012;Blaber et al., 2005;Bulanin et al., 2017a).Several species of groupers have been successfully cultured and studies intensively worldwide (Ruckert et al., 2009;Solis et al., 2013;Puebla et al., 2014;Bulanin et al., 2017b).This study indicate that Simeulue Island has a big potency as center for marine culture in Indonesia, because this island has higher diversity of commercial marine fishes  2): 77-84 DOI: 10.13170/ajas.2.2.9584 80 which have potency to be cultured, for example within the group of Serranidae and Lutjanidae.Beside, the Simeulue Island has many appropriate sites for floating cages nets for fish culture (Purnawan et al., 2015).

CONCLUSION
A total of 7 orders, 26 families, 54 genus and 77 species of marine fishes were recorded in Simeulue Island waters.Serranidae and Lutjanidae are predominant based on number of species.
