“…Kendala utama pembenihan siput gonggong adalah masih rendahnya tingkat pemijahan induk dan tingkat kelangsungan hidup (survival rate, SR) larva di wadah budi daya (Muzahar et al, 2019), disamping itu sumber induk matang gonad masih mengandalkan penangkapan dari alam. Salah satu cara yang paling efektif dalam menstimulasi pemijahan organisme akuatik adalah melalui manipulasi hormonal (Yudha et al, 2017). Proses reproduksi siput laut Thais clavigera dan kerang Sinonovacula constricta dikendalikan oleh hormon (Lu et al, 2001;Yan et al, 2011).…”

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.

“…Ada tiga pendekatan yang biasa dilakukan dalam merangsang pemijahan biota akuatik, yaitu manipulasi lingkungan, hormonal, dan pakan. Menurut Yudha et al (2017), cara yang paling efektif dan efisien dalam memacu perkembangan reproduksi ikan adalah manipulasi hormonal. Peranan dan mekanisme hormon pada pemijahan siput belum banyak dikaji, namun keberadaan dan peranan hormon dalam beberapa moluska telah dilaporkan oleh beberapa peneliti.…”

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 ìLgÎ¹ bobot badan lunak (BB) (P1); 0,7 ìLgÎ¹ BB; dan 0,9 ìLgÎ¹ 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 ìLgÎ¹ soft body weight (BW) (P-1), 0.7 ìLgÎ¹ BW; and 0.9 ìLgÎ¹ 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.

The consequences of climate change, in general, are changes in temperature and extreme season. Related to the fish gonad maturation, the effect of temperature can be distinguished by its effect on fish depending on the pattern of the reproduction and spawning season. In fish that spawn seasonally, rising temperatures in the tropical area signal the fish to ripen the gonads and migrate to the spawning area for ovulation in the early spawning season. Therefore, changing in the beginning and its duration of the season related to climate change will affect the maturity of fish gonads. In this paper communication, controlling gonad maturation on snakehead for eliminating impact of climate change is discussed. Observation of the gonad development on thirty mature snakehead stocks in Bogor, West Java, was conducted every month during a year. The obtained data were then compared to a similar previous study in the same area to have better insight on the impact of climate change on gonad development. To eliminate natural signal influence on the snakehead spawning, the study of gonad maturation in spawning (August to January) and out spawning season (February to July) using combination hormone of Pregnant Mare Serum Gonad (PMSG) and Anti Dopamine (AD) was done. The study used three breeders for each season, the dosage hormone of 2 mL/kg body weight was injected every month when the eggs were starting to develop, from September to November for spawning season and from May to July for out spawning season. The observed parameters were eggs diameter, fecundity, estradiol concentration, and gonadosomatic index. The results showed that reproductive performance tends to decline and fluctuate compared to the previous study done two years earlier. The highest eggs diameter, fecundity, and gonadosomatic index were in November. Hormone treatments in spawning and out spawning season were not significantly different (P>0.05) in the eggs diameter. The concentration of estradiol in the spawning season were higher than out spawning season, but they were not significantly different (P>0.05). Thus, hormone induction out the spawning season enabled to enhance breeder maturation as in the spawning season. Based on the result, hormone treatment could be used as an alternative to control maturation on the snakehead breeders from the impact of climate change.
