Abstract

Keberhasilan pemijahan menentukan ketersediaan benih siput gonggong. Tujuan penelitian ini adalah menganalisis efektivitas penggunaan jenis hormon berbeda yaitu ovaprim® dan hCG dalam menstimulasi pemijahan siput gonggong. Delapanpuluh empat pasang induk disuntik sesuai rancangan dengan ovaprim® atau hCG, atau kombinasi keduanya masing-masing dengan dosis 0,5 µL/g BB. Induk pascasuntik dipijahkan dalam akuarium dengan densitas 7 pasang per akuarium. Parameter yang diamati adalah: jumlah induk yang memijah, jumlah telur dikeluarkan oleh induk, waktu latensi, dan tampilan histologi gonad induk. Uji Kruskal Wallis digunakan untuk menganalisis data jumlah induk mijah, dan analysis of variance (ANOVA) untuk menganalisis jumlah telur dikeluarkan oleh induk siput. Hasil penelitian menunjukkan tidak ada perbedaan signifikan (P>0,05) jumlah induk mijah di antara perlakuan, namun pemberian hCG memberikan jumlah induk mijah paling tinggi (52,38%). Waktu latensi induk mijah umumnya mulai mijah pada hari ke-2 dan ke-3 setelah pemberian 0,5 µL/gBB ovaprim. Berdasarkan persentase induk mijah dan nilai seluruh parameter pengamatan disimpulkan bahwa pemberian suntikan hCG dosis 0,5 µL/g BB (P1) memberikan respons lebih baik dibanding perlakuan lain.

Abstract

An intensive exploitation of dog conch Strombus sp. in Tanjungpinang city coastal waters has occurred because the increasing number of fishermen, population growth and demand. In addition, the increasing activities of bauxite mining cause the declining in quality of waters around dog conch, thus providing ecological pressure that endangers sustainability of the dog conch. The purpose of this study was to observe the spawning and development of dog conch in the laboratory. Spawning was done in aquarium with 100 liters of seawater (salinity: 26±1 ppt), with stimulation of spawning performed by changing 90% water volume every day until the female issued the eggs. The female issued the eggs on the third and fourth days of stimulation. Eggs are attached to the wall of the aquarium. Egg cell division occurs after about 2 hours of the egg is released the mother, from one cell into two cells and a row into four cells, eight cells, the sixteen cells, thirty-two cells to multicellular. The embryo develops into a gastrula phase than trochophore phase. Larvae were reared in a tank containing 20 liters of seawater (salinity: 26±1 ppt). Veliger larvae occurred on the fifth day until the eleventh day. Veliger larvae are planktonic, and turn into benthic with a sedentary life in the bottom waters to begin the formation of a thin and transparent shell. The value of water quality parameters during maintenance category feasible: DO of 7.6 to 7.8 mg / L; pH of 8.13 to 8.33; turbidity of 1.97 to 3.90 NTU, salinity of 26.8 to 27.8 ppt; and temperature of 25.8-27.8°C.

Abstract

Dog conch Laevistrombus turturella is captured intensively, therefore, their population is decline. The dog conch culture is needed to maintain their population. The technology towards conch reproduction is still not developed yet in Indonesia. The 17β-estradiol hormone in conch and some mollusks has been stated by some researcher yet its main role in conch reproduction process has not widely known. The study about the addition of 17β-estradiol hormone in accelerating gonad development has never been reported. The aim of this study was to evaluate the impact of the addition of 17β-estradiol against dog conch’s gonad development. This study used three treatments for three groups of dog conch those were without injection (P1), injection by 30 µL of corn oil mixed with absolute ethanol (P2), and 30 µL of 17β-estradiol stock solution (P3). After injection, the dog conch was reared in pens culture in their natural habitat for 30 days. This study showed that the injection of a 17β-estradiol solution (P3) stimulated the dog conch’s gonad development as evidenced by greater oocyte mean diameter than another treatment. The mean of gonadal weight and GSI on P3 treatment was also higher than treatments P1 and P2. SDS-PAGE analysis showed that dog conch’s hemolymph has several kinds of proteins with varying molecular weights. Proteins with a molecular weight of 54-55 kDa are predicted as dog conch’s vitellogenin.

Abstract

Siput gonggong, Laevistrombus turturella termasuk komoditas perikanan laut yang memiliki nilai ekonomi tinggi di Pulau Bintan Provinsi Kepulauan Riau. Hemolim pada siput berperan penting dalam sistem pertahanan tubuh dan reproduksi. Penelitian ini bertujuan untuk mengetahui total hemosit dan diferensial hemosit pada siput gonggong asal Pulau Bintan. Penelitian dilaksanakan pada bulan Juli-Agustus 2021. Sampel siput gonggong berasal dari perairan laut Kampung Madong dan Lobam. Hemolim diambil dari otot kaki gonggong untuk pemeriksaan total hemosit dan diferensial hemosit. Data dianalisis secara deskriptif. Hasil penelitian menunjukkan total hemosit, persentase hyalin dan sel granular siput gonggong dari Kampung Madong dan Lobam relatif sama dan dalam kisaran normal (< 1,0 x 106 sel/mm3). Jumlah total hemosit siput gonggong asal Kampung Madong dan Lobam secara berturut-turut adalah berkisar antara 77.000-166.600 sel/mm3 dan 71.000-165.000 sel/mm3, persentase sel hyalin berkisar antara, 58%-80% dan 52%-70%, serta persentase sel granular berkisar antara 20%-42% dan 30%-48%. Oleh karena nilai total hemosit dan diferensial hemosit relatif sama maka siput gonggong asal Kampung Madong disarankan sebagai kandidat calon induk karena memiliki ukuran tubuh 6,52 ± 5,61 cm lebih besar dibandingkan asal Lobam 5,27 ± 0,40 cm.Gonggong conch, Laevistrombus turturella is a marine gastropod highly valued as a seafood commodity in Bintan Island Riau Islands Province. The farming technology of the species is currently not available due to limited information on its biology including its immune system and reproduction. Hemolymph in conchs plays an important role in gonggong conch body’s defense system and reproduction. This study aimed to determine the total haemocytes and hemocytic differential of gonggong conchs originated from Bintan Island. The research was conducted between July-August 2021. The gonggong conch samples were collected from the coastal waters of Kampung Madong and Lobam. Hemolymph was taken from the gonggong conch leg muscles for examination of total hemocytes and hemocytic differential and analyzed descriptively. The results showed that the total hemocytes, percentage of hyaline and granular cells of gonggong conchs from Kampung Madong and Lobam were relatively similar and within the normal range (< 1.0 x106 cell/mm3). The total number of haemocytes of gonggong conchs from Kampung Madong and Lobam ranged from 77,000-166,600 cells/mm3and 71,000-165,000 cells/mm3; respectively, while the percentages of hyaline cells ranged between 58%-80% and 52%-70%, respectively, and the percentage of granular cells ranged between 20%-42% and 30%-48%. Gongong conch from Kampung Madong had a body size of 6.52 ± 5.61 cm which was larger than that of Lobam with body size of 5.27 ± 0.40 cm. Because both had relatively similar values of total haemocytic and haemocytic differential, the gonggong conch from Kampung Madong was suggested as the best candidate for broodstock.

Abstract

Gonggong adalah sejenis siput laut yang merupakan makanan laut (seafood) favorit dan ikon Kota Tanjungpinang, ibukota Provinsi Kepulauan Riau (Kepri). Gonggong mengandung protein tinggi, yaitu sekitar 46,65%. Tidak ada laporan tentang produksi budidaya dan upaya konservasi gonggong. Teknologi produksi benih buatan gonggong belum berkembang. Tujuan penelitian ini adalah untuk mengevaluasi pemberian kombinasi hormon LHRH-a dan antidopamin untuk menginduksi proses pemijahan. Evaluasi pemberian hormon LHRH-a dan antidopamin pada pemijahan siput gonggong dilakukan dengan empat dosis: 0,5 ìLgι bobot badan lunak (BB) (P1); 0,7 ìLgι BB; dan 0,9 ìLgι BB (P2); dan tanpa suntikan (TS). Siput gonggong pascasuntikan dipelihara di akuarium selama 14 hari. Hasil penelitian menunjukkan bahwa (1) kombinasi hormon LHRH-a dan antidopamin mampu merangsang pemijahan gonggong. Dosis rendah hormon LHRH-a dan antidopamin (P-1) menghasilkan induk betina yang memijah paling banyak, yaitu 34,48%; lebih tinggi dari P-2 (27,59%), P-3 (20,69%); dan TS (17,24%); (2) jumlah telur yang dikeluarkan oleh induk betina berbeda secara signifikan antar perlakuan (P<0,05). Jumlah telur yang dikeluarkan oleh masing-masing induk berkisar antara 10.874-63.489 butir/ekor dengan rata-rata 39.347 ± 16.667 butir/ekor.The gonggong is a species of sea conch which is a favourite seafood and an icon of Tanjungpinang City, capital of Kepulauan Riau (Kepri) Province. Gonggong contains high protein, about 46.65%. There were no reports on aquaculture production and conservation effort of gonggong. The technology on artificial seed production of gonggong has not yet developed. The aim of this study was to evaluate the administration of LHRH-a hormone and anti-dopamine to induce the spawning process. Evaluation of the administration of LHRH-a hormone and anti-dopamine on the gonggong conch’s spawning was carried out with four doses: 0.5 ìLgι soft body weight (BW) (P-1), 0.7 ìLgι BW; and 0.9 ìLgι BW (P-2); and without injections (TS). The gonggong conchs after injection were reared in aquarium for 14 days. The results showed that (1) a combination of LHRH-a hormone and anti-dopamine was able to stimulate gonggong spawning. The lower dose of LHRH-a hormone and anti-dopamine (P-1) produced the highest number of spawned female broodstock, which was 34.48%, higher than P-2 (27.59%), P-3 (20.69%), and TS (17.24%); (2) the number of eggs released by female broodstock was significantly different among the treatments (P<0.05). The number of eggs released by each female broodstock ranges between 10,874-63,489 grains/ind. with an average of 39,347±16,667 grains/ind.

Abstract

Fase larva pada siput gonggong sebagaimana pada biota akuatik lain adalah fase yang peka dan rawan kematian. Penyerapan kuning telur untuk pembentukan organ dalam terjadi pada fase ini. Suhu air memengaruhi perkembangan embrionik dan metabolisme dalam tubuh biota. Informasi tentang pengaruh suhu inkubasi terhadap embriogenesis dan perkembangan larva siput gonggong masih terbatas. Penelitian ini bertujuan untuk menentukan pengaruh suhu berbeda terhadap embriogenesis dan perkembangan larva siput gonggong. Percobaan menggunakan rancangan acak lengkap dengan tiga perlakuan dan dua ulangan. Tiga perlakuan perbedaan suhu yang diberikan yaitu 27°C, 29°C, dan 31°C. Sampel telur yang digunakan berasal dari hasil pemijahan semibuatan. Hasil penelitian menunjukkan bahwa inkubasi pada suhu air 31°C memberikan stimulasi tercepat pada embriogenesis dan perkembangan larva siput gonggong daripada perlakuan lainnya. Larva siput gonggong menetas dan berenang bebas pada jam ke-94 pasca-inkubasi. Penelitian dengan perlakuan yang sama perlu dilanjutkan untuk dapat menghasilkan benih siput gonggong.Similar to most of the other aquatic biota, the larval phase of gonggong conch is considered a sensitive and death-prone life stage. The absorption of egg yolk to form the internal organs occurs in this phase. Certain external factors, particularly water temperature, play a significant influence on the embryonic development and metabolic processes of gonggong conch larvae. However, the extent of the effects of incubation temperature on the embryogenesis and larval development of gonggong conch has not been determined or thoroughly studied. This study aimed to determine the effects of different temperatures on the embryogenesis and larval development of gonggong conch. The experiment used a completely randomized design with three treatments and two replicates. The temperature treatments were 27°C, 29°C, and 31°C. The egg samples used were collected from the semi-artificial spawnings of gonggong conch. The results showed that the egg incubation using the water temperature of 31°C provided the fastest stimulation in the embryogenesis and development of gonggong conch larvae than the other treatments. Gonggong conch larvae hatched and swam freely in the 94th hours post-incubation. Research with the same treatment needs to be continued to be able to produce gonggong conch seeds.

Abstract

Overfishing makes the population of gonggong conch even smaller in their habitat. Its preservation can be maintained by cultivating gonggong conch, including by preparing mature gonads through induction using gonadotropim hormone. This study aims to obtain an effective type of hormone treatment in accelerating the maturation process of the gonggong conch gonads. This research was conducted in April - July 2020 at the Laboratory of the Faculty of Maritime Science and Fisheries, Raja Ali Haji Maritime University, Tanjungpinang, Kepri Province. The method used is a completely randomized design (CRD) with 4 treatments and 3 replications, injection treatment NaCl 0,5µL/head (K), injection treatment oodev® 0,5µL/head (PA), injection treatment PG600® 0,5µL/head (PB), injection treatment oodev® 0,25 µL + PG600® 0,25 µL/head (PC). The results showed that the highest GSI value is PC treatment (0.12±0.36%). Effective treatment in accelerating the process of maturing of gonggong conch gonads is a PC treatment because it reaches TKG II through the histology result ogf gonad. The highest absolute weight growth of the gonggong conch was the PC treatment (0.07±0.01 g). The highest growth length of the gonggong conch was the PC treatment (0.83±0.23cm).
