UDANG ROSTRIS (Litopenaeus stylirostris) KOMODITAS  PROSPEKTIF BAGI USAHA PERTAMBAKAN

Blue shrimp (Litopenaeus stylirostris) known as “SS” (Super Shrimp) originated as wild larvae from Panama, and is currently in its 22nd generation of domestication. They have undergone a systematic process of selection for enhancement of growth and fecundity, and in particular, for resistance improvement to the IHHN virus.The SS-blue shrimp are significantly more tolerant to low water temperatures than Penaeus monodon or Litopenaeus vannamei. This characteristic was effluent to the broodstock management of blue shrimp. The critical phase of larval rearing is on the interchange from zoea to mysis, but almost no mortality on the post larvae stadium. It was observed during larvae rearing using modulation system indicated by the survival rate of nauplius to PL 5 was 29%, but PL 5 to PL 15 reached 97%. Growth of larvae and post larvae in the modulation and non modulation systems were not significant different, but performance and uniformity of the seed in modulation system shown better. Its avarage production in grow out pond was 9,000 kg/ha with final survival rate of 74.5-94.8%, and avarage daily growth (ADG) of 0.176 g. The ponds were stocked with SS-shrimp at densities of 33-38/m2.

Artemia sp. is a common natural feed for shrimps at the post-larvae stage and is characterized by poor lipid content. Therefore, Artemia is commonly enriched with specific nutrition, including biofloc. This contains some useful nutrients in the form of protein and polyhydroxy butyrate (PHB). The aim of this study was to analyze the effect of Artemia enriched with biofloc on the growth performance of black tiger shrimp, P. Monodon, and whiteleg shrimp P. vannamei. This research used acompletely randomized design (CRD), encompassing three treatments of feed and four replications. The tested treatments include: (a) Artemia sp. without enriched (b) Artemia enriched with biofloc, and (c) biofloc without Artemia, and the treatments were fed on black tiger as well as whiteleg shrimp post-larvae for 15 days. The results showed the significant effect of using Artemia sp. enriched with biofloc on the growth of P. monodon and P. vannamei, but not on the survival rate. However, both parameters were significantly influenced for post-larvae shrimp at a dose of 30 mL biofloc. This served as a nutritional source by providing the best growth of 14.57 mg and 15 mg at a daily growth and survival rate of 0.86 mg day-1: 98% and 1.4 mg day-1: 99% for P. vannamei and P. monodon, respectively.

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.

Masalah utama yang umum terjadi pada produksi benih abalon adalah kematian yang tinggi (> 90%) setelah abalon menempel pada plate pemeliharaan. Penggunaan pakan dalam bentuk tepung untuk mengganti diatom sebagai pakan postlarva beberapa spesies ikan, udang, dan abalon sudah dilakukan. Penelitian ini bertujuan untuk mendapatkan jenis pakan dalam bentuk tepung yang sesuai dan efektif untuk mendukung sintasan dan pertumbuhan larva abalon Haliotis squamata. Percobaan terdiri atas lima perlakuan pakan pada pemeliharaan larva abalon yaitu tepung Spirulina sp., Ulva sp., Chaetoceros sp., Gracilaria sp., dan diatom (kontrol). Masing-masing perlakuan terdiri atas empat ulangan. Pakan berupa tepung yang digunakan pada masing-masing perlakuan, terlebih dahulu dicampur merata dengan larutan tepung agar (7,5 mg/mL dalam air laut; suhu 40°C) dengan konsentrasi tepung 40 mg/mL larutan agar. Pemberian pakan dilakukan setiap tiga hari dengan cara menyemprotkan larutan pakan pada permukaan plate pemeliharaan larva. Penelitian dilakukan selama 30 hari. Hasil penelitian menunjukkan bahwa sintasan larva abalon yang diberi pakan tepung Spirulina sp. paling tinggi dan berbeda nyata (P<0,05) dengan yang diberi diatom, tepung Chaetoceros sp., dan Ulva sp., yaitu masing-masing 81,49%; 79,25%; 76,57%; dan 76,46%; tetapi tidak berbeda nyata dengan yang diberi pakan tepung Gracilaria sp. 81,37% (P>0,05). Laju pertumbuhan harian panjang cangkang larva abalon tertinggi diperoleh pada larva yang diberi pakan tepung Gracilaria sp. (203,81 ± 1,23 µm/hari) dan Spirulina sp. (205,59 ± 1,71 µm/hari). Nilai laju pertumbuhan harian panjang cangkang larva abalon yang paling rendah dijumpai pada larva yang diberi pakan tepung Ulva sp. (146,07 ± 1,73 µm/hari).The most common problem in abalone seed production is the high mortality occurrence (> 90%) after postlarvae settlement to the rearing plates. The use of microparticle diets to replace the natural feed of postlarval has been performed on various species of fish, shrimp, and abalone. This research aims to determine the most effective and suitable powder-based feed to support the survival and growth of abalone Haliotis squamata larvae. The experiments consisted of five feed treatments, i.e., Spirulina sp., Ulva sp., Chaetoceros sp., and Gracilaria sp. Flour, and diatoms (as control). Each treatment had four replicates. The powder-based feed used in each treatment was firstly mixed with a solution of agar powder (7.5 mg/mL sea water, 40°C) with a concentration of 40 mg of flour/mL of agar solution. Feeding was done every three days by spraying the feed solution onto the surface of the larval rearing plate. The study was conducted for 30 days. The results showed that survival rate of abalone larvae fed with Spirulina sp. flour was the highest and significantly different (P<0.05) compared with those given diatoms, Chaetoceros sp. and Ulva sp. flours, which were 81.49%, 79.25%, 76.57%, and 76.46%, respectively, and not significantly different from those fed with Gracilaria sp. 81.37% (P>0.05). The highest daily growth rate of the shell length of abalone larvae was achieved by larvae fed with Gracilaria sp. (203.81 ± 1.23 ¼m/day) and Spirulina sp. flours (205.47 ± 1.71 µm/day). The lowest daily growth rate of shell length was found on abalone larvae fed with Ulva sp. flour (146.07 ± 1.73 µm/day).

Asian moon scallop, Amusium pleuronectes, is among the most common commercially harvested scallop in the Philippines. This study investigated suitable conditioning methods, induced spawning, and documented scallop larval development at the Marine Fisheries Research and Development Center (MFRDC) Guiuan, Eastern Samar. Scallops held in tanks with flow-through water system without substrate yielded high survival rate of 48.06 ± 5.95%. Optimum water temperature was 28-29°C for maintaining scallops. Isochrysis galbana and Chaetoceros calcitrans were suitable microalgal feed for A. pleuronectes consumed at 7,388,888 cells min-1 per scallop. These significant results were applied in maintaining scallops at the hatchery. As a result, scallops with an average 19.8 mm shell length (SL) reached 37.5 mm SL within four months with a survival rate of 96.57 ± 2.04%, average daily growth rate (ADGR) of 0.13 ± 0.04 mm.day-1, and specific growth rate (SGR) of 3.92 ± 1.31%.d-1. Natural spawning was successful under controlled conditions while induced spawning trial through thermal stimulation, food shock, sexual stimulation, and serotonin injection resulted unsuccessful release of sperm and eggs. The estimated number of fertilized eggs per spawning ranged from 0.22-1.4 million. Fertilized eggs appeared spherical and dark in color with 54.2-62.57 µm in diameter. After nine hours, the larvae developed into trochophore stage with 59.08-84.4 µm in length. D-veliger with 120.37-157.07µm shell length developed after 24 hours. Development of the early umbone stage was reached on day 5; and on day 7, the umbo larvae become well-developed with shell length of 135.45-173.36 µm. On day 9, pedi-veligers were observed in the culture. Spat grew 312.41-509.48 µm on day 16 and survived until four months with final shell length of 4-10 mm. For the larval rearing, stocking density of A. pleuronectes larvae observed highest survival rate of 0.04 ± 0.03% at 200 larvae/L, while no larvae survived at 800 larvae/L due to contamination of protozoans in the culture medium.
