“…Some species, for example, Blacktip reef shark (Carcharhinus monopteros), Whitetip reef shark (Triaenodon obesus) and Grey reef shark (Carcharhinus amblyrhynchos), are well-studied especially for ecology and behaviour. Mukharror et al, 2017), (Ichsan et al, 2015), (Sofyan et al, 2020) Blacktip reef shark Carcharhinus melanopterus (Ahmad Mukharror et al, 2017), (Ichsan et al, 2015) (Mukharror et al, 2019) (Sofyan et al, 2020), (Saputra, 2022), (Mukharror et al, 2020), (Mukharror et al, 2021;Sentosa et al, 2020) Halmahera walking shark Hemiscyllum halmahera (Ichsan et al, 2015) Oceanic (Ichsan et al, 2015), (Sofyan et al, 2020) The sightings record of this species in Morotai will help inform local authorities and can be used as a recommendation to strengthen the species and habitat protection and improve the exposure of Morotai as a shark tourism centre in Indonesia. In the last few years, the government of Morotai has made shark and shark-diving activities their flagship theme for marine tourism, even promoting Gorango Morotai (GOMO) as their regional mascot (Abdullah, 2020) where Gorango is 'shark' in the local language.…”

Tawny nurse shark (Nebrius ferrugineus) is a species of carpet shark distributed across the tropical Indo-Pacific region. Tawny nurse shark is listed as “Vulnerable” on IUCN Redlist and rarely seen, recorded and studied in Indonesia. We recorded this species during SCUBA diving activity in Morotai waters in April 2022. Scientific record of the species is highly important for conservation and habitat management, particularly in Morotai, a region in North Maluku famous for shark-based marine tourism.

Morotai has abundant marine biological resources, sharks being one of them. The blacktip reef shark is one of the dominant types of coral reef sharks in Morotai waters. Worldwide shark are threatened due to the demand for shark fins and over fishing, to protect sharks is important to know their distribution so protected areas can be established. This research aims to examine the distribution of blacktip reef sharks (Carcharhinus melanopterus) based on habitat characteristics in the Morotai Waters. Through surveys and observation of coral cover, using the Line Intercept Transect (PIT) method and the Baited Remote Underwater Video (BRUV) to record the blacktip reef sharks who passed by the coral reef. Water quality parameters measured include temperature, salinity, visibility, acidity, current type, tides, and moon phases. Blacktip reef sharks were found in three of the four research stations. Station 4 was the one with the most blacktip reef shark appearances, amounting to 91 individuals. This station has the lowest sloping contour and has the smallest live coral cover of only 1%. Station 4 is dominated by sand covering 40%. All water quality parameters influence blacktip reef shark occurrence. The highest appearance of the blacktip reef shark happens during the new moon phase, when the tides are loose and the currents are quite strong.

“…This area has been identified as a priority for sustainable fisheries management (Retnoningtyas et al 2017). Many studies have investigated the reef fish (Nabil et al 2018) and sharks (Pridina 2015;Ichsan et al 2016;Mukharror et al 2019;Mukharror et al 2020), and also their relative abundance (Mukharror et al 2018). However, no study has yet measured the relationship between the biomass of reef fish and shark.…”

Abstract. Sofyan JF, Ambariyanto A, Suwartimah K, Toha AHA. 2020. Relationship between the biomass of reef shark and fish in South Morotai Waters, North Maluku, Indonesia. Biodiversitas 21: 5605-5613. This study aims to determine the biomass of reef shark and fish in South Morotai Waters in North Maluku, Indonesia. The Audible Stationary Count and Underwater Visual Census method were used to collect the data of reef sharks and fish. Seven and one site locations of coral reef and shark ecosystems were surveyed and, the data were analyzed using regression analysis to obtain a correlation between the variables. The three reef sharks found were Carcharhinus melanopterus, Triaenodon obesus, and Carcharhinus amblyrhynchos. Biomass estimation of reef sharks and fish ranged from 0.59 to 19.97 kg/ha and 30.95 kg/ha to 49.92 kg/ha, consisting of 8 families. In the area of aggregations, both species were found in 7 sites, and the population of reef shark amounted to 86.96 kg/ha and fish was around 55.705 kg/ha, consisting of 9 families. There was a positive relationship between the biomass of reef shark and fish in South Morotai waters, and the index of determination was 0.8043, showing that the biomass of reef shark was influenced by that of fish. These results indicated the importance of biomass in determining the functional composition and diversity of reef shark and fish.
