The seaweed Caulerpa racemosa cultivation unit used in this study was the off-bottom method measuring 5 m x 10 m. This size can contain 5 stretch ropes/risers with a length of 10 m and a distance of 1 m between the stretch ropes/risers. Each stretch / riser line contains about 45 seed clump points with a distance between clumps of 15 cm. The observation procedure for the growth of Caulerpa racemosa seaweed was carried out by weighing the seaweed seeds in each stretch/riser rope. The weight of seed that is weighed is the weight of seeds at the time of planting and the weight of seaweed at harvest.The results showed that the average growth rate of seaweed Caulerpa racemosa was varied for each rope. In ris 1 rope, the average absolute weight growth reached 100.88 grams, ropes 113.33 grams, ris rope 3, 88.00 grams, rope ris 4, 116.00 grams, and rope ris 5, amounting to 113, 33 grams. In general, the highest growth in absolute weight was found in the fourth rope, which was 116.00 grams.

The purpose of this research is to understand the condition biophysics of seagrass (Types of seagrass, Cover of seagrass, fish, makrozoobenthos, types of substrat, water brightness, the depth of the seagrass) and to establish the suitability of seagrass to support nautical ecotourism. This research have been done in Sibu island, Guraping village, north oba district, Tidore city for 6 month from April â€“ September 2020. The method that used is a survey method consist of direct measuring of types seagrass, cover of seagrass, fish, makrozoobenthos, types of substrat, water brightness, the depth of the seagrass. The data analysis includes percentage of cover seagrass and the suitability index of seagrass ecotourism. The result of the biophysical study were obtained are 8 types of seagrass, cover of seagrass (51,04- 92,71%), fish (12 types), makrozoobenthos (17 types), brightness (77-100%), substart (sand, muddy sand, mud) flow speed (0,01- 0,06 m/dt) and the depth of the seagrass (1-2,5 m). Sibu island could be developed as a region of Seagrass Ecotourism with index suitability tourism (IKW) station 1,3,4 and for the whole are located in category S1 (very suitable) and station 2 is in the suitable category.

This study was conducted with the aim of knowing the composition of gastropod species that live in the seagrass area of Tafaga and Figur coastal waters, Moti Island and to determine the structure of the gastropod community which includes density, diversity, dominance and species evenness. The sampling technique was carried out using the 50x50 m block area method. The composition of gastropod species found in coastal waters of Tafaga (station 1) was 6 species and coastal waters of Figure (station 2) were 17 species. The highest density of gastropod species in station 1 was found in the Nassarius pullus species and the lowest in the Naria erosa species. Meanwhile, in the station 2, the highest density of gastropod species was also found in the Nassarius pullus species and the lowest in the Strombus lentiginosus species. The diversity of gastropod species at station 1 is low and there are species that dominate and the distribution of species is quite even. While at station 2 the species diversity is moderate and no species dominates and the species distribution is evenly distributed.

. Seagrass ecosystem is one of the coastal ecosystems that can provide food supply and improve the living standards of coastal residents. The objectives of the study were to determine the composition of the seagrass species on Toduku Island, to determine the composition of the seagrass biota species, to determine the community structure of seagrass species and associated biota including species diversity, species dominance and species density and to determine the interaction pattern of the utilization of seagrass fisheries resources by the community around Toduku Island. . The method used is field observation and Participatory Rural Appraisal (PRA). The composition of seagrass species in Toduku Island are Enhalus acoroides, Thalassia hemprichii, Halophila minor, Cymodocea rotundata, Halodule pinifolio, and Syringodium isoetifolium. The composition of the biota that inhabits the seagrass beds of Toduku Island consists of fish, crabs and macrozoobenthos (Holothuroidea, Echinoidea, Asteroidea, gastropods, bivalves). The diversity of seagrass and biota species is moderate, there is no dominant species and the distribution of each species is very even. The pattern of interaction in the use of seagrass resources has been patterned for generations. The forms of utilization activities carried out by the community include taking mollusks (snails, clams), echinodes (sea cucumbers, sea urchins), catching fish and crabs.

The purpose of this study was to determine the effect of spacing on the growth of seaweed Halymenia sp with the off-bottom method, and determine the spacing that gave the best effect on the growth of seaweed Halymenia sp with the off-bottom method. This research was conducted in Kastela coastal waters, Ternate Island District, Ternate City. The initial weight of the Halymenia sp clump used refers to the initial weight of the K. alvarezii clump which is about 50 g/clump. The stretch rope used is a polyethylene (PE) rope with a diameter of 4 mm and a length of 15 m with a distance of 1 m between the stretch ropes. Maintenance is carried out by the off-base monoline method. Data analysis was used to determine the growth of cultivated Halymenia sp seaweed. The data analyzed were absolute weight growth data, which was obtained from the difference between the average weight at the end of rearing and the initial weight when stocked/planted and the relative growth rate. The results showed that the spacing of seaweed Halymenia sp had a very different effect on absolute weight growth and relative growth of seaweed Halymenia sp, where a 25 cm spacing gave the best results on absolute weight growth and relative growth of seaweed Halymenia sp.

Seaweed of Caulerpa racemosa has bright prospects for cultivation. In North Maluku province in general, the cultivation of seaweed Caulerpa sp has never been developed, even though the waters of North Maluku have enormous potential, because this type of seaweed is scattered in various marine waters in North Maluku. One of the efforts that needs to be done is to carry out this type of seaweed cultivation in an optimal and sustainable manner.The seaweed Caulerpa racemosa cultivation unit used in this study was the off-bottom method measuring 5 m x 10 m. This size can contain 5 stretch ropes/risers with a length of 10 m and a distance of 1 m between the stretch ropes/risers. Each stretch / riser line contains about 45 seed clump points with a distance between clumps of 15 cm. The observation procedure for the growth of Caulerpa racemosa seaweed was carried out by weighing the seaweed seeds in each stretch/riser rope. The weight of seed that is weighed is the weight of seeds at the time of planting and the weight of seaweed at harvest.The results showed that the average growth rate of seaweed Caulerpa racemosa was varied for each rope. In ris 1 rope, the average absolute weight growth reached 100.88 grams, ropes 113.33 grams, ris rope 3, 88.00 grams, rope ris 4, 116.00 grams, and rope ris 5, amounting to 113, 33 grams. In general, the highest growth in absolute weight was found in the fourth rope, which was 116.00 grams.
