Abstract

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.

Abstract

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.

Abstract

Coconut crabs (Birgus latro) is a fishery resource that is only found in eastern Indonesia, and the waters of Ternate City are an area that has this potential.  This research aims to determine the size distribution and habitat characteristics of coconut crabs in Tomajiko, Hiri Island District. The data collection method consists of several stages, namely determining stations, distributing bait, catching coconut crabs, morphometric measurements, and observing environmental parameters. Determination of stations in this study was carried out based on topographic differences in Tomajiko (divided into two stations). Coconut crab catching uses the roaming survey method. The bait used is coconut meat that has been split into several parts and coconut meat that has been mashed. The morphometric dimensions measured were chest length (carapace length) and body weight. The habitat characteristics observed were the type and extent of vegetation, organic matter content and substrate texture, environmental parameter measurements (soil temperature, air humidity and soil pH). The results of the research showed that the coconut crabs caught at both stations had relatively the same length, but the largest weight was found at station 2. Habitat characteristics in Tomajiko, Hiri Island strongly support the survival of coconut crabs.

Abstract

Macrozoobenthos are benthic animals commonly found in substrate-based ecosystems, such as mangrove forests. Their presence in mangrove ecosystems significantly influences the decomposition activities within the substrate or sediment layers. The aim of this study was to identify species composition, species density, community structure of macrozoobenthos, and their vertical distribution within sediments on mangrove ecosystem in Ternate City. The study was conducted from August to September 2021 using the line transect method, with macrozoobenthos samples collected through iron pipe corers. Data analysis included species density, species diversity, dominance index, evenness index, niche width, microhabitat niche overlap, and the relationship between macrozoobenthos density and depth. The results showed that the macrozoobenthos species composition consisted of two species (Uca spp. and Nereis spp.), with a total of 25 individuals. Species diversity within mangrove ecosystem was found to be low, with one dominant species and a relatively even distribution. The species with the broadest habitat niche was the worm (Nereis spp.), while significant microhabitat niche overlap occurred between the worm (Nereis spp.) and the crab (Uca spp.). Simple linear regression analysis indicated that substrate depth did not correlate with macrozoobenthos species density.Keywords:aquaticbenthoscoastalfaunaterrestrial
