A total of 11 100 x 10m2 belt transects were used to. investigate sea cucumber community in Un bay Sample of sea 3 Results and discussion. cucumber was collected during low tide by hand picking Sea 3 1 Species composition. cucumber found in each transect were identified counted and A total of 104 individual which consist of five genuses of sea. measured based on their sex Species identification was based cucumber namely Holothuria four species Stichopus three. on 3 5 23 while sex was determined based on the general species Actinopyga one species Bohadschia two species. appearance color and texture of the gonads Prior to and Thelonota one species were found in Un bay during the. measurement sea cucumber was let to relax for about 10 study Table 1 Two species found in the present study i e. minutes Length was recorded as the distance between mouth Holothuria scabra and Thelenota ananas are considered as the. and anus to the nearest mm using plastic rules while weight most valuable species of sea cucumber in international market. was weighted using digital balance Genus Holothuria had more species than other genuses. Deviation of sex from normal ratio 1 1 for male and female More species belong to genus Holothuria is also recorded by. was tested using chi square with Yates correction proposed some authors such as 25 in Central Maluku waters six. by Fowler and Cohen 1990 8 species and 31 in Pai Padaido four species Rowe 1969 23. stated that genus Holothuria has the most species recorded in. 2 O E 0 5 2 E the world i e more than 114 species Furthermore Yusron. 2009 32 reported that genus Holothuria has more species. Where O oberserved frequency than other genus of sea cucumber in Indonesian waters. E expexted frequency especially in Western Pacific Number of species found in the. present study is similar to the number of species recorded by. Length weight relationship was analysed using the power some authors Yusron 2004 31 reported 10 spesies of sea. function according to Pauly 1984 21 cucumber in Pai Padaido Lewerissa 2014 17 found nine. species in Porto Saparua Island Meanwhile Yusron, W aLb Widianwari 2004 33 found 14 species in Kai Besar. Lewerissa 2009 16 reported 18 species in Porto and. Where W weight in gram Warialau waters and Selanno et al 2014 25 recorded 22.

The value of b was then tested and used to determine growth not only in seagrass bed but also in coral reef Whereas. pattern of sea cucumber i e isometric growth b 3 or Selanno et al 2014 25 conducted their study at wider area in. allometric growth b 3 by using t Student test based on Pauly three islands i e Ambon Saparua and Haluku. 1984 21 The interval value of b was calculated by using.

The results in Table 1 show that most individuals of sea 3 2 Size distribution. cucumber found in this study belonged to genus Holothuria Size distribution of sea cucumber in term of length and weight. i e 85 individuals followed by genus Stichopus as many as 14 in Un bay is presented in Table 2 It can be seen in Table 2 that. individuals while the least individual is represented by genus H scabra has minimum length and weight while maximum. Actinopyga and genus Thelonata Higher abundance of genus size is represented by S variegates Information on size. Holothuria is also reported by Yusron 2004 31 in Pai distribution and abundance of marine organism is important in. Padaido and by Selanno et al 2014 25 in Central Maluku managing marine resources In high level of exploitation. Higher number of sandfish H scabra 82 individuals found which cause overfishing is indicated by lesser catch and. in this study might indicate that habitat in Un bay with smaller animal caught Wouthuyzen et al 1984 29. substrate dominated by sand is suitable for this species.

A total of 82 individuals of sandfish H scabra were Yusron 1991 30 It can be seen in Table 3 that small. collected during the study hence further analysis was individuals 9 cm was not found in Un bay This. conducted for this species which covered length frequency phenomenon is also reported by 1 20 30 According to Mercier. distribution sex ratio and length weight relationship et al 1999 18 and Murphy et al 2011 20 small individuals. Length frequency distribution of H scabra is presented in of sea cucumber are rare or difficult to find in a certain area. Table 3 The body length of H scabra found in this study because of their habit to burry themselves in the substrates and. ranged from 9 5 to 23 3 cm This finding is similar to the size only active during the night.

Data presented in Table 3 also shows that population of 16 cm while Kithakeni and Ndaro 2002 14 stated that its. sandfish H scabra in Un bay is dominated individuals at first spawning occurs at 16 8 cm Based on those statements it. midlength 16 5 17 5 and 19 5 cm which consist as many as 40 can be concluded that most of the individual H scabra found. individuals 49 of the total samples collected According to in Un bay consists of adult individuals 73 2 which have.
