Abstract

Clams have a planktonic period which is sensitive to metal pollutants in the waters. The natural concentration of cadmium (Cd) is relatively low in marine waters but may increase with increasing anthropogenic activity on land that may be lethal to organisms, especially in the sensitive larval stages. The purpose of this study was to analyze the values of 24h-LC50, NOEC (No Observed Effect Concentration), LOEC (Lowest Observed Effect Concentration) and MATC (Maximum Acceptable Toxicant Concentration) along with the impact of acute Cd toxicity on mortality and morphological changes of Tridacna squamosa veliger. The toxicity test used was an acute toxicity test with a static method (4 replications). Acute toxicity tests were performed on veliger phase larvae with short-term exposure (24 hours) on various Cd concentrations ie., 0.1 mg/L, 1 mg/L, 2.5 mg/L, 5 mg/L and 10 mg/L . The 24h-LC50 value was calculated using the Trimmed Spearman-Karber application version 4.1, and the LOEC and NOEC values were analyzed using the Dunnet test. Results showed that the 24h-LC50 value of Cd applied to Tridacna squamosa veliger was 2.12 mg/L, whereas the NOEC, LOEC, and MATC values were 1 mg/L, 2.5 mg/L, 1.581 mg/L respectively.  Mortalities were observed with increasing Cd concentrations. It was also shown a decreasing number of zooxanthellae, damaged in mantle tissue and shells, changes in shell color, released of mantle tissue from the shell with increasing Cd concentrations.

Abstract

The aims of this research were to discover the density of algae symbiont of zooxanthellae in the giant carpet anemone (Stichodactyla gigantea) from the nature and the asexual reproduction by longitudinal body fragmentation technique. The research was conducted from October 2007 to July 2008, in The Hatchery of University of Hasanuddin Marine Station in Barrang Lompo Island for seed production and coral reefs area of Barrang Lompo Island for the implementation of culture. The series of study was started with parental collection and acclimatization of anemones, fragmentation of the body, culturing anemones in the coral reefs area and collection of algae zooxanthellae which is conducted every two months. The results of this study indicated the difference of zooxanthellae density from nature and asexual reproduction anemones. The highest density of zooxanthellae algae found in the non fragmented or nature population (AA) (10.84 x 106 cell/cm2), followed by the anemone which was resulted from 2 parts body fragmentation (AF2) (10.24 x 106 cells/cm2), and the anemone which was resulted from 4 parts body fragmentation (AF4) (9.17 x 106 cell/cm2 ). Whereas, between the good coral (KB) and bad coral (KR) not significant.

Abstract

Program Pengabdian Kepada Masyarakat Unhas-Program Kemitraan Masyarakat (PPMU-PK-M) “Kelompok Pembudidaya Kuda Laut (Hippocampus barbouri) di Pulau Sabangko, Desa Mattiro Bombang Kecamatan Liukang Tupakbiring Kabupaten Pangkep” bertujuan untuk meningkatkan pengetahuan dan keterampilan mitra dalam menjalankan usaha budidaya kuda laut. Metode pelaksanaan PK-M, terdiri dari kegiatan budidaya kuda laut dan kegiatan pendampingan. Pada kegiatan budidaya kuda laut ini, wadah yang digunakan terbuat dari akuarium kaca berukuran 80(P) x 40(L) x 50(T) cm dan berukuran 60(P) x 40(L) x 40(T) cm. Wadah pembesaran kuda laut didesain menggunakan sistem resirkulasi yang dilengkapi dengan saluran pemasukan air (in let) dan saluran pembuangan air (out let) serta dilengkapi pompa celup, aerasi, tempat sangkutan untuk bertenggernya kuda laut. Unit penangkaran ini juga dilengkapi dengan sistem suplai air laut dan instalasi tenaga surya. Penyediaan kuda laut juvenil dan dewasa diperoleh dari hasil penangkaran/budidaya kuda laut di Laboratorum Penangkaran dan Rehabilitasi Ekosistem Fakultas Ilmu Kelautan dan Perikanan Universitas Hasanuddin. Selanjutnya kuda laut tersebut ditebar dan dipelihara hingga mencapai ukuran dewasa atau calon induk sesuai target yang diharapkan. Jumlah kuda laut yang dipelihara masing-masing sebanyak 50 ekor juvenile berukuran 5 - 6 cm dan calon indukan sebanyak 50 ekor berukuran 8 - 9 cm. Hasil pemeliharaan/pembesaran kuda laut menunjukkan sintasan yang sangat tinggi yaitu berkisar 96 - 100% dan telah mencapai ukuran calon indukan dan indukan dengan ukuran panjang masing-masing berkisar 10 hingga 11 cm dan 12 hingga 13 cm. Selama kegiatan program PK-M, kelompok mitra terlibat secara langsung pada semua tahapan-tahapan budidaya kuda laut. Kata kunci: Budidaya, kuda laut Hippocampus barbouri, sintasan. ABSTRACT Unhas Community Service Program-Community Partnership Program (PPMU-PK-M) “Sea Horse (Hippocampus barbouri) Cultivation Group on Sabangko Island, Mattiro Bombang Village, Liukang Tupakbiring District, Pangkep Regency” was conducted to increase the knowledge and skills of partners in running a seahorse farming business. The PK-M implementation method consists of seahorse cultivation and mentoring activities. For seahorse cultivation activity, the container used is made of a glass aquarium measuring 80(W) x 40(L) x 50(H) cm and 60(W) x 40(L) x 40(H) cm. The seahorse rearing containers were designed as a recirculation system which equipped with inlet and outlet along with submersible pumps, aeration and objects for seahorses to coiling tails. This unit system was also equipped with seawater supply system and solar power installation. The juvenile and adult seahorses were obtained from captive breeding/cultivation of seahorses at the Laboratory of Sea ranching and Ecosystem Rehabilitation, Faculty of Marine Sciences and Fisheries, Hasanuddin University. The seahorses were subsequently stocked and reared until the animals reach the adult size or prospective broodstock according to the targeted size. The number of cultivated seahorses was 50 for 5 - 6 cm juveniles and 50 of 8 - 9 cm prospective broodstok. The results of the seahorse cultivation showed a very high survival rate ranging from 96 - 100% and attained prospective broodstock and broodstock lengths ranging from 10 to 11 cm and 12 to 13 cm, respectively. During the PK-M program activities, each member of partner groups was actively involved in all stages of seahorse cultivation activities. Keywords: Cultivation, seahorse Hippocampus barbouri, survival.

Abstract

Seaweed cultivation activities in Jeneponto Regency have been practised for a long time and have become the main livelihood for most of the Mallasoro Bay community. In cultivating seaweed, obstacles often arise in the form of failures experienced by seaweed farmers or poor-quality yields. This study was aimed to develop alternative planting calendars for Eucheuma sp. in Mallasoro Bay, Jeneponto Regency based on sea surface temperature and distribution of chlorophyll-a obtained from Landsat-8 imagery. Image Processing Sea Surface Temperature and Chlorophyll-a were processed using ENVI 4.8 AND 5.3 software, the satellite images used were clean and without cloud disturbance. In this study, data analysis was carried out descriptively. The water temperature that is good for seaweed growth is 27-30˚C, for Mallasoro Bay Sea Surface Temperature which is suitable for seaweed cultivation, namely April, May, June, July, August, September, October and November. While the classification is based on the criteria for chlorophyll-a trophic status in marine waters, namely the range < 1 mg/L is classified as Oligotrophic, ≥ 1–3 mg/L is classified as Mesotrophic, ≥ 3–5 mg/L is classified as Eutrophic, and > 5 mg/L is classified as Hypertrophic. , from the results of image analysis for the distribution of chlorophyll-a in Mallasoro Bay, it shows that Mallasoro Bay is at the Mesotrophic level throughout the year or the fertility level of the waters is quite fertile because it is in the range of ≥ 1–3 mg/L. so that a seaweed planting calendar can be obtained in Mallasoro Bay, namely in January, February and December, preparation of tools such as cleaning and repair of seaweed planting tools can be carried out, then at the end of March, the end of May, the end of July and the end of September, the procurement of seaweed seeds is carried out. , in early April, early June, early August, and early October, seaweed seeds can be spread, then in mid-May, mid-July, mid-September, and mid-November, harvesting can be carried out, so that seaweed cultivation can be carried out 4 times in one year. cycle.
