<p>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 (<em>Litopenaeus vannamei</em>) postlarvae during rearing period. Design experiment was completely randomized design with five treatments and three replications of natural food <em>Chironomus</em> 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 PL<sub>25 </sub>from acclimatization in media 2 ppt with addition of potassium 25 ppm to freshwater media.  The densities of PL<sub>25</sub> 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 (PL<sub>25</sub>) gave best performance production compared to which only that was given natural food <em>Chironomus</em> 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 PL<sub>54</sub> 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 PL<sub>25</sub> 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.</p> <p>Key words: salinity, natural food, artificial diet, Pacific white shrimp</p> <p> </p> <p>ABSTRAK</p> <p>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 <em>Chironomus </em>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 PL<sub>25 </sub>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 PL<sub>25</sub>) 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 (PL<sub>54</sub>)  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 PL<sub>25</sub> 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.</p> <p>Kata kunci: salinitas, pakan alami, pakan buatan, udang vaname.</p>

The growth and survival of Litopenaeus vannamei post larvae was measured in controlled different salinities condition 35ppt (T1), 40ppt (T2), 45ppt (T3) and 50ppt (T4) were maintained. Group of Shrimp post larvae (weight 0.032 g ± 0.002) were stocked at a density of 35 nos. /aquarium in above salinity ranges. Animals were fed with commercial feed (35% Crude Protein) @ 5% of body weight four times a day. The results indicate that higher SGR was observed in T2 (1.99±0.08) followed by T1 (1.75±0.07), T3 (1.54±0.06) and T4 (1.49±0.17). Highest survival (100 %) was recorded in T1 followed by T2 (96.42%), T3 (94.99%) and T4 (74.21%). From the results of the present study it could be seen that higher salinity significantly reduced the growth and survival of L. vannamei but will also open study area of physiological adaption of animal at higher saline water in performance of organisms.

In the present investigation, we evaluated if the presence of tilapia affects growth and survival of shrimp during pre-growth and grow-out phases. In both experiments, we used a random-blocks design in a single earth pond (0.75 ha) that was prepared and divided into nine (7 x 30 m) enclosures that were considered to be three blocks of three enclosures each. Each randomly stocked block consisted on Pacific white shrimp Litopenaeus vannamei (30 shrimp/m2) and three different densities (0.0, 0.25 and 0.50 fish/m2) of red tilapia hybrids (Oreochromis mossambicus x Oreochromis niloticus) to give three different treatments with three replicates. The results from the pre-growth and grow-out experiments followed the same trend. In both cases, we found no significant statistical differences (P>0.05) in the final average weight of the shrimp. However, the experimental blocks had a significant (P<0.05) effect on the mean sample weight of shrimp. Shrimp in blocks B and C were significantly bigger than shrimp from block A (P<0.05). For both experiments, we found no effect of the presence of tilapias on survival or growth of shrimp.RESUMENEvaluamos si la presencia de tilapias libres afecta el crecimiento y la supervivencia de camarones en fase de preengorda y engorda. Para ambos experimentos, utilizamos un diseño de bloques al azar en un estanque rústico (0.75 ha) que fue preparado y dividido en nueve encierros (7 x 30 m), se formaron tres bloques con tres encierros cada uno. Cada encierro dentro de cada bloque fue aleatoriamente seleccionado para sembrar camarón blanco del Pacífico, Litopenaeus vannamei (30 camarones/m2) y tres diferentes densidades (0.0, 0.25 y 0.50 peces/m2) de híbrido de tilapia roja (Oreochromis mossambicus x Oreochromis niloticus) para formar tres tratamientos con tres réplicas. Los resultados del experimento de pre-engorda y engorda siguieron la misma tendencia. En ambos experimentos no encontramos diferencias estadísticamente en el crecimiento de los camarones ni en las tilapias. Sin embargo, los bloques experimentales presentaron diferencias significativas (P<0.05) en el peso promedio final. Los camarones de los bloques B y C fueron estadísticamente más grandes (P<0.05) que los del bloque A. Para las dos etapas de crecimiento de los camarones, no se observó un efecto de la presencia de tilapias sobre la sobrevivencia o crecimiento de los camarones.
