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.

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.

PENGARUH PEMBERIAN HORMON 17β-ESTRADIOL TERHADAP PERKEMBANGAN GONAD SIPUT GONGGONG Laevistrombus turturella Muzahar; Muhammad Zairin Jr.; Fredinan Yulianda; Muhammad Agus Suprayudi; Alimuddin; Irzal Effendi

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.

Siput gonggong Laevistrombus turturella merupakan siput laut yang banyak dikonsumsi masyarakat di Provinsi Kepulauan Riau sehingga populasinya diperkirakan menurun. Upaya pelestarian siput ini perlu dilakukan salah satunya dengan budidaya. Kegiatan budidaya memerlukan ketersediaan induk matang gonad. Tujuan penelitian ini adalah menganalisis ukuran induk siput gonggong matang gonad berdasarkan panjang cangkang dan warna gonad, serta mengevaluasi pengaruh paparan suhu berbeda terhadap kecepatan penentuan jenis kelamin induk. Panjang cangkang siput gonggong diukur dengan jangka sorong, kemudian dipecahkan untuk mengamati warna gonadnya. Data dianalisis dengan student t-test. Perlakuan paparan suhu air 15°C (P1), 20°C (P2), dan 30°C (P3). Tujuh ekor induk siput gonggong dimasukkan ke dalam akuarium sesuai perlakuan, durasi waktu keluar tubuh lunak siput gonggong dari cangkang dicatat. Data dianalisis dengan uji Kruskal Wallis. Hasil penelitian menunjukkan ukuran rata-rata panjang cangkang induk siput gonggong matang gonad dari laut Madong-Tanjungpinang adalah 63,449±5,352 mm (jantan) dan 66,953±5,876 mm (betina). Penentuan jenis kelamin siput gonggong dapat dipercepat dengan pemberian kejutan suhu dengan suhu air 20°C.
