Abstract

This research was conducted to determine natural food substitution time by artificial diet   after salinity acclimatization from 20 ppt until 2 ppt, which can increase survival and growth of (Litopenaeus vannamei) postlarvae during rearing period. Design experiment was completely randomized design with five treatments and three replications of natural food Chironomus sp.  (60% of crude protein) substitution time by artificial diet (40% of crude protein) at day: 1 (A), 7 (B), 14 (C), 21 (D) and full natural food without artificial diet (E) during 28 days rearing period. White shrimp postlarvae and rearing media in this experiment based from best result of earlier research that is PL25 from acclimatization in media 2 ppt with addition of potassium 25 ppm to freshwater media.  The densities of PL25 white shrimp were 20 PLs/50 liters of 2 ppt media. The result of this experiment showed that the use of artificial diet as soon as after salinity acclimatization (PL25) gave best performance production compared to which only that was given natural food Chironomus sp. during experiment or with treatment by artificial diet substitution at day-7, day-14 or day-21, shown with the highest value of food consumption level, protein retention, energy retention, daily growth rate and food efficiency. Survival rate of PL54 was above 80% and not significant different between treatment. That is supported by chemical-physical value of water quality still in range appropriate to survival rate of white shrimp post larvae during a rearing period. The result of this experiment indicated that requirement nutrient of PL25 in low salinity did not fulfilled if only rely on natural food, so that require artificial diet with nutrition content to support growth and survival rate of white shrimp post larvae more maximal. Key words: salinity, natural food, artificial diet, Pacific white shrimp   ABSTRAK Tujuan penelitian ini adalah untuk menentukan waktu penggantian pakan alami oleh pakan buatan yang tepat selama masa pemeliharaan postlarva udang vaname di media bersalinitas rendah setelah melalui masa aklimatisasi penurunan salinitas dari 20 ppt hingga 2 ppt, sehingga dapat meningkatkan pertumbuhan dan kelangsungan hidup. Rancangan percobaan berupa rancangan acak lengkap dengan perlakuan yang diterapkan berupa waktu penggantian pakan alami Chironomus sp. (kadar protein 62%) oleh pakan buatan (kadar protein 40%) pada hari ke-1 (A), ke-7 (B), ke-14 (C), ke-21 (D) dan pakan alami (E) selama masa pemeliharaan. Postlarva udang vaname dan media pemeliharaan yang dipergunakan selama percobaan mengacu pada hasil terbaik yang didapatkan dari penelitian pendahuluan yaitu berupa PL25 hasil aklimatisasi di media bersalinitas 2 ppt  dengan penambahan kalium 25 ppm ke media air tawar pengencer. Padat tebar sebanyak 20 ekor/50 liter/wadah. Hasil percobaan menunjukkan bahwa pemberian pakan buatan yang diberikan segera setelah masa aklimatisasi salinitas (pada awal pemeliharaan PL25) memberikan performa produksi budidaya terbaik bila dibandingkan dengan yang hanya diberi pakan alami selama masa pemeliharaan maupun waktu penggantian pakan alami oleh pakan buatan pada hari ke-7, ke-14 dan hari ke-21 yang ditunjukkan dengan tingkat konsumsi pakan, retensi protein, retensi energi, laju pertumbuhan harian dan efisiensi pakan yang tertinggi.  Kelangsungan hidup di akhir pemeliharaan (PL54)  di atas 80% dan tidak berbeda nyata antar perlakuan. Hal ini ditunjang oleh nilai fisika kimia air yang berada dalam kisaran yang layak selama masa pemeliharaan. Hasil percobaan ini menunjukkan bahwa kebutuhan nutrisi pada stadia PL25 di media bersalinitas rendah tidak terpenuhi jika hanya mengandalkan pakan alami sehingga perlu ditunjang dari pakan buatan dengankandungan nutrisi yang dapat mendukung pertumbuhan dan kelangsungan hidup yang lebih maksimal. Kata kunci: salinitas, pakan alami, pakan buatan, udang vaname.

Abstract

Budidaya udang galah di lahan suboptimal rawa masih mengalami kendala karena tingkat mortalitas yang tinggi pada stadia pascalarva terutama saat penebaran awal di media air rawa. Kondisi perairan rawa yang kurang sesuai untuk budidaya udang galah perlu ditingkatkan daya dukungnya terutama yang berhubungan dengan kemampuan osmoregulasi dan metabolisme pascalarva udang galah, salah satunya berupa penambahan mineral kalsium. Penelitian ini bertujuan untuk menentukan penambahan kadar kalsium terbaik yang dapat menghasilkan sintasan, tingkat kerja osmotik, dan tingkat konsumsi oksigen terbaik pada pascalarva udang galah selama masa adaptasi pergantian media hidup dari media bersalinitas 12 ppt ke media air rawa 0 ppt, selama 10 hari mulai dari udang galah stadia PL1 hingga PL11 dengan penurunan salinitassecara gradual dan persentase volume. Rancangan percobaan yang digunakan yaitu rancangan acak lengkap dengan lima perlakuan penambahan kalsium pada air rawa pengencer salinitas media, yaitu 0 mg.L-1 (A), 25 mg.L-1 (B), 50 mg.L-1 (C), 75 mg.L-1 (D), dan 100 mg.L-1 (E). Parameter yang diamati yaitu tingkat sintasan, tingkat kerja osmotik, tingkat konsumsi oksigen, kadar kalsium tubuh, dan kualitas fisika kimia media adaptasi. Hasil penelitian menunjukkan bahwa penambahan 50 mg.L-1 kalsium (C) dapat meminimalisir tingkat kerja osmotik terendah yaitu 192,90 mOsm.l-1 H2O dan tingkat konsumsi oksigen 2,678 mgO2.g-1.jam-1.. Selain itu, juga dapat menyebabkan kadar kalsium tubuh hingga mencapai 8,029 mg/L dan sintasan yang diperoleh mencapai 94%. Selama penelitian berlangsung parameter fisika kimia media adaptasi (suhu, pH, oksigen terlarut, amonia, dan alkalinitas) masih dalam kondisi yang dapat ditolerir bagi sintasan udang galah.

Abstract

This research was conducted to determine the closed transportation system with biomass and water volume ratio that can support the osmoregulation ability of glass eel significantly. Glass eel was obtained from catching activities in the Cimandiri River, Pelabuhan Ratu (mean length 52.40+0.84 mm and weight 0.10+0.01 g) and acclimatized for 24 hours at salinity 6 mg L-1 and temperature 20°C gradually.The research design was a completely randomized design. The applied treatment was glass eel closed transportation system with various ratio of glass eel biomass (kg): water volume (L), i.e. 1:11; 1:12; 1:13; and 1:14 during 24 hours of land transportation and continued with a 3-day recovery period.The water was used refer to the above acclimatization method, with ratio the water part of pure oxygen in a plastic bag was 1:3. The measured parameters include survival rate, osmotic gradient, body hydromineral, and water quality in transport packaging and recovery medium. Survival rates were generated in the high range until recovery period (P<0.05), but the transportation method caused differences significantly (P<0.05) in osmotic response and hydromineral status (sodium, chloride, potassium, and water content), so that it will affect production performance in the next stage of culture. Ratio of glass eel biomass: water volume of 1:13 has been able to support the ability of osmoregulation glass eel to maintain homeostatic condition during the transportation until 3 days of recovery period. There was no drastic decline in physical and chemical value of water in the transport bag so it could reduce the mortality rate for 24 hours.
