Abstract

Suritech (sea urchin technology) is a technology machine for threshing sea urchin spines for the production of sea urchin egg kukure. Sea urchins are echinoderms whose entire body surface is covered with venomous spines. The purpose of this study was to determine the speed, capacity and production of sea urchin eggs based on the Suritech machine. The purpose of this research is to provide information on how to manufacture suritech machines in managing sea urchins. The Suritech machine is capable of producing 100 sea urchins per 4 minutes or 36.000 urchin per day. The production of sea urchin eggs by the Suritech machine is able to beat the production of sea urchin eggs in Japan, which is only around 27.000 tons per day. Thus, the use of the Suritech machine as a thresher of sea urchin spines is expected to increase fishermen's income and position South Sulawesi as the center of sea urchin egg production in Indonesia.

Abstract

Sea urchin is echinoderm that body surface is covered with the spines. Sea urchin gonad has been consumed along time by the people at Wakatobi Archipelago. Sea urhin species is worried will be degraded. On the other hand, there is no study on species composition, density, size and maturity stage of sea urchins on Tolandono Island and Sawa Island, Wakatobi Regency. The purpose of this study was to determine the species composition, abundance, size and maturity level of sea urchin gonads. Sea urchin density was calculated with a 10 × 10 m transect quadrate. The data was analyzed by descriptive qualitatively. The results showed that in Tolandono Island and Sawa Island there were 4 types of sea urchins, namely Tripneustes gratila, Echinotrix calamaris, Diadema setosum and Echinoemetra sp. The size of urchin Tripneustes gratilla is ranging between 2.5 cm and 8.5 cm with the density 2 Ind./100 m². Meanwhile, the gonad maturation stage (TKG) of Tripneustes gratila is at a 4.8 cm and spawned at a size 8–8.5 cm. TKG I is in the size range of 4.8–5 cm, TKG II is at 5.9–6.2 cm, TKG III is 6.4–6.6 cm, TKG IV is 6.8–7.5 cm and TKG IV is 6.8–7.5 cm. V in size 8.5 cm.

Abstract

This study aims to determine the abundance and distribution patterns of sea urchins in Botubarani Waters, Kabila Bone District, Bone Bolango Regency. This research was conducted from July to August 2020. A total of three research stations were established, namely West Tamboa, Central Tamboa and East Tamboa. The abundance of sea urchins was calculated using a quadrant transect measuring 1 × 1 m, which was laid 25 m perpendicular to the coastline using a line transect. Sea urchin species found were identified in situ and the distribution pattern of sea urchins was calculated using the morista dispersion index. The results showed that there were 5 types of sea urchins in Botubarani Beach, namely Echinometra mathaei, Diadema setosum, Echinotrix calamaris, Echinotrix diadema and Tripneustes gratilla. The sea urchin type Echinometra mathaei is the species with the highest abundance in all research stations, namely 25 ind./m2 at Tamboa Barat station, 9 ind./m2 at Tamboa Tengah station and 7 ind./m2 at Tamboa Timur station. The distribution patterns of sea urchins found in Botubarani waters include clusters for Echinometra mathaei and uniform patterns for sea urchins Diadema setosum, Echinotrix calamaris, Echinotrix diadema and Tripneustes gratilla. ANOVA analysis results show that there is no significant difference between sea urchin abundance and water quality parameters in all research stations. This indicates that there is no difference in environmental conditions at the three sampling locations.

Abstract

Sea urchin is an abundant fisheries resources in Pisou Village, Pagimana District, Central Sulawesi. This abundance is caused by the high productivity of sea urchins and the lack of utilization by the local community. The high density of sea urchins causes the poor quality of gonad and taste. This is mainly caused by the insufficient availability of food in the nature that can be only improved by aquaculture. This community empowerment was conducted in the Pisou Village for 5 weeks from February-March 2020. The aim of this program is to cultivate sea urchins in improving the quality of sea urchin gonad by aquaculture. Another goal is to educate the local fishers on how to culture and utilized the gonad a seafood and crackers. The result of this activity is the availability of floating net cages at Desa Pisou Village that can be used for sea urchin cultivation.
