Density and morfometric analysis of sia-sia (Sipunculus nudus) from Nusalaut island beach waters central Maluku

Abstract

Sia-sia (Sipunculus nudus) has a shape resembling a worm, is an organism that usually lives in coastal areas, especially around seagrass areas, this biota tends to inhabit the bottom of the water especially in the substrate so that it is categorized as an infauna benthic organism and is able to inhabit areas with soft and hard substrates. This is a deskriptive type of research, to describe or describe information about the density and morphometrics of Sia-sia from the coastal waters of Nusalaut Island, Central Maluku. The results of the study on the density of Sia-sia on the island of Nusalaut, differ according to location, based on the results of the density calculation obtained. Each location shows the total average value of Absolute Density (KA) is 0,0063 ind/m2 (Low) and Relative Density (KR) is 100%. The Absolute density level (KA) in Abubu Vilage is 0,0068 ind/m2 (Low), the absolute density level (KA) in Ameth Villlage is 0,0064 ind/m2 (Low) and the absolute density level (KA) in Akoon Village is 0,0058 ind/m2 (Low), Based on the results of the Sia-sia morphometric research from Nusalaut Island, the Results vary from each village with Sia-sia morphometric average length of 12,14 cm, width 2,15 cm and weight of 31,6 g, followed by Akoon village with Sia-sia morphometric average length of 11.6 cm, width 2,21 cm, and a weight of 33,6 g, and the last one is Ameth Village with an average length of Sia-sia morphometric that is 13,02 cm, width 2,26 cm, and weight 36 g

Peanut worms as unreported fishery resources in Brazil

“…Dried sa‐sung is sold in stores or even in websites as a Pho condiment because of their strong umami taste. Poor communities in Indonesia may use them as a daily side dish when the fishing declines and there is no other source of protein (Ferdinandus et al, 2022).…”

Variasi Spasial Kepadatan Cacing Kacang di Pantai Toronipa Sulawesi Tenggara

“…Perpaduan substrat pasir dan vegetasi lamun yang rapat menjadikan Pantai Toronipa sebagai kawasan yang sesuai dengan preferensi habitat S. australeaustrale (Wati et al 2021). Secara ekologi, cacing kacang merupakan organisme benthos infauna yang mendiami liang-liang substrat sebagai sarangnya sehingga kehidupan biota ini sangat bergantung pada fraksi substrat yang relatif didominasi oleh pasir kasar (PK) hingga pasir yang sangat halus (PSH) untuk memudahkan proses lokomosinya di dalam substrat (Ferdinandus et al 2022;Wati et al 2021;Li et al 2019;Nam et al 2019;Li et al 2017;Hsu et al 2013;Nguyen et al 2007). Komposisi substrat demikian memudahkan cacing kacang dalam melakukan aktivitas meliang (ruang hidup sebagai media melangsungkan semua aktivitas biologi; fisiologi) dan mendapatkan makanan (serasah lamun).…”

“…Keberadaan cacing kacang di Pantai Toronipa (Wati et al 2021;Nurhikma et al 2017) dan perairan lainnya di seluruh Indonesia (Ferdinandus et al 2022;Silaban & Rieuwpassa, 2019;Rahayu et al 2019;Rahayu 2018;Fakhrurrozi, 2011;Pradina 1993) bahkan di seluruh dunia (Li et al 2019;Nam et al 2019;Li et al 2017;Zhang et al 2011) ditandai oleh munculnya gundukan-gundukan (mounds) di ekosistem lamun (seagrass beds) dan terlihat jelas pada saat kondisi perairan sedang surut (low tide). Setiap gundukan dihuni oleh satu (individu) cacing kacang, dengan kedalaman liang berkisar 50-200 mm (Wati et al 2021).…”

“…Kondisi yang sama juga ditemukan pada daerah lainnya di Sulawesi Tenggara, seperti Wakatobi (pesisir Sombu) (Rahayu 2018;Rahayu et al 2019), dan Buton Utara . Begitu pula di beberapa bagian di wilayah Indonesia, cacing ini ditemukan (Fakhrurrozi 2011;Pradina 1993;Leiwakabessy et al 2017;Silaban et al 2019;Ferdinandus et al 2022). Walaupun cacing kacang di Pantai Toronipa mempunyai kepadatan tinggi, perlu adanya pengelolaan sumber daya dan lingkungannya, terutama pengaturan kuota tangkapan dan perbaikan habitat yang terdegradasi karena perluasan objek wisata di Pantai Toronipa.…”

Sipuncula (Peanut Worms) in Indonesia Waters: A Review

“…Studies on Sipuncula in Indonesia primarily focus on its nutritional content (minerals, nutrient fatty acids) (Fakhrurrozi, 2011;Nurhikma et al, 2017;Rahayu et al, 2019;Silaban, 2012Silaban, , 2017Silaban, , 2018Silaban, 2019;Fatimah et al, 2021;Yuslina, 2022). Limited research is available on the biological and ecological aspects of Sipuncula species (Hoeksema and Best, 1991;Erliani, 2021;Erliani et al, 2021;Ferdinandus et al, 2022;Matulessy, 2021), while studies related to the genetics and the influence of Sipuncula on ecosystems are almost nonexistent (Table 1.). Based on existing studies, this paper attempts to summarize the species distribution, habitat, utilization, and future management options and research for Sipuncula in Indonesia.…”
