Abstract

The whale shark (Rhincodon typus Smith, 1828) is the largest extant fish species in the world, and it is endangered, with population numbers declining in the last three decades. The appearance of whale sharks in the Botubarani Waters has attracted a lot of attention. Therefore, this study aimed to determine the whale shark's appearance, their habitat constellation pattern, and its oceanographic conditions. This research was conducted during the 2019-2022 period. The Photographic Identification (Photo-ID) method is used to observe and determine whale shark individual's number and pattern of presence. Oceanographic data includes chlorophyll-a concentration using Ocean Color Image (CCI) data and sea surface temperature (SST) using OSTIA image data processed with Interactive Data Language (IDL) software. The research showed there are 38 individuals with an estimated total length ranging from 2.3 to 7.3 meters. All whale sharks appearing in Botubarani include juvenile male individuals with a composition of 53% new individuals (N=20) and 47% (N=18) old individuals seen again with a rare seasonal and sporadic presence pattern mainly in the Eastern season (June). The average SST value during the study period ranged from 28.36-30.29⁰C while chlorophyll-a ranged from 0.174-0.698 mg.m-3. Although the present findings show that the whale shark's appearance in Botubarani waters was not significantly influenced by SST and chlorophyll-a, it might be affected by other oceanography factors such as Sea Surface Height Distribution (SSHD) and depth (Bathymetry). As the Botubarani aggregation site is the only whale shark emergence area with easy access throughout the year and is rapidly developing into a new ecotourism industry in Indonesia; the information on whale shark appearance provides useful support for the sustainable protection and Whale Sharks conservation in the future.

Abstract

The whale shark (Rhincodon typus) is the largest fish species in the world that is not aggressive to humans, so it has become a popular tourist icon. The presence of whale sharks has become a tourist magnet and has transformed Botubarani Village from an ordinary fishing village into a bustling tourist village. However, the Covid19 pandemic has dealt a severe blow to whale shark tourism on the coast of Botubarani Village. The drastic reduction in tourists not only eliminates tourist income but also stops whale shark monitoring activities. The government's New Normal pilot is the hope for the return of whale shark tourism on the coast of Botubarani Village. Preparations for the opening of PPKM in the area of ​​origin of tourists and the ease of domestic/foreign travel will be greeted with an increase in the quality and innovation of whale shark tourism at Botubarani Beach. In addition, the adaptation of tourism during the pandemic by utilizing the internet is quite promising so that tourism will stay alive. The Innovation Village of Botubarani develops a live broadcast of an underwater virtual cruise with whale shark objects periodically in the wild. This development is the first in Indonesia because it has never been done before. The use of underwater closed circuit television (CCTV) that can be accessed on land and integrated with the internet allows whale sharks on Botubarani Beach to be enjoyed by anyone and anywhere. Villages and communities on Botubarani Beach can receive input from ongoing tourism developments from tourists who come or virtually. Tourists may also be interested in coming after watching a live broadcast of whale sharks on the beach of Botubarani Village. In addition, live video recording of whale sharks can also be utilized by intellectuals, government and industry as part of the triple helix collaboration.
