Availability of good-quality shrimp feed is an important factor of shrimp increased production. High protein feed can be generated by adding raw materials that contains high protein. One of the raw materials that contains high protein is earthworm meal (Lumbricus sp.). This research goal was to study the influence of the substitution of fish meal by earthworm feed with different proportions toward growth and survival rate of tiger shrimp larvae (Penaeus monodon). The experimental design used Completely Randomized Design (RAL) consists of five treatments with three replications: Feed test A (25%  earthworm meal + 75% fish meal), feed test B (50% earthworm meal + 50% fish meal), feed test C (75% earthworms meal + 25% fish meal), feed test D (100% earthworms meal) and feed test E (commercial feed). Results showed that the tiger shrimp which given feed test E is the best result for tiger shrimp growth with 0.480 ± 0.076 grams/individual, while feed test B was the best result for tiger shrimp survival rate with 82 ± 3.46%., and on the feed test D was the best result for tiger shrimp feed conversion rate with 4.0 ± 0.17. Based on results of statistical tests showed that the substitution of fish meal with earthworm meal did not give significant effect on growth and survival rate of tiger shrimp.

Salinity is one of the most important abiotic factors affecting growth, metabolism, immunity and survival of aquatic species in farming environments. As a euryhaline species, the black tiger shrimp (Penaeus monodon) can tolerate a wide range of salinity levels and is farmed between brackish to marine water conditions. The current study tested the effects of six different salinity levels (0‰, 2.5‰, 5‰, 10‰, 20‰ and 30‰) on the selected physiological, biochemical and genetic markers (individual changes in the expression pattern of selected candidate genes) in the black tiger shrimp. Experimental salinity levels significantly affected growth and survival performance (p < 0.05); the highest levels of growth and survival performance were observed at the control (20‰) salinity. Salinity reductions significantly increased free fatty acid (FFA), but reduced free amino acid (FAA) levels. Lower salinity treatments (0–10‰) significantly reduced hemolymph osmolality levels while 30‰ significantly increased osmolality levels. The five different salinity treatments increased the expression of osmoregulatory and hemolymph regulatory genes by 1.2–8-fold. In contrast, 1.2–1.6-fold lower expression levels were observed at the five salinity treatments for growth (alpha amylase) and immunity (toll-like receptor) genes. O2 consumption, glucose and serotonin levels, and expression of osmoregulatory genes showed rapid increase initially with salinity change, followed by reducing trend and stable patterns from the 5th day to the end. Hemocyte counts, expression of growth and immunity related genes showed initial decreasing trends, followed by an increasing trend and finally stability from 20th day to the end. Results indicate the farming potential of P. monodon at low salinity environments (possibly at freshwater) by proper acclimation prior to stocking with minimal effects on production performance.

Administration of probiotic bacteria can be conducted through artificial feed or live food such as <em>Artemia</em>. This study was done to examine the effectiveness of various doses of probiotic <em>Vibrio</em> SKT-b through <em>Artemia</em> on the growth and survival of post-larval shrimp. Tiger shrimp at a stage of PL 10 was reared in glass jars filled with 2 L of sea water at a density of 10 larva/L. The study consisted of five probiotic concentrations control (0 cfu/mL), A (10<sup>3</sup> cfu/mL), B (10<sup>4</sup> cfu/mL), C (10<sup>5</sup> cfu/mL), and D (10<sup>6</sup> cfu/mL). Administration of various doses of probiotic bacteria <em>Vibrio</em> SKT-b through <em>Artemia</em> significantly increased the growth rate in term of the length and weight, but had no effect on survival. The results found that treatment D (10<sup>6</sup> cfu/mL) gave an increase in body weight, length and survival rate of 22.53%/day, 0.080 cm/day and 95%, respectively.</p><p class="NoParagraphStyle"> </p><p class="NoParagraphStyle">Keywords: probiotic, <em>Artemia</em>, tiger shrimp</p><p class="NoParagraphStyle"> </p><p class="NoParagraphStyle"> </p><p class="NoParagraphStyle" align="center"><strong>ABSTRAK</strong></p><p class="NoParagraphStyle"> </p><p class="NoParagraphStyle">Aplikasi bakteri probiotik merupakan salah satu alternatif teknologi untuk meningkatkan produksi budidaya udang yang ramah lingkungan.

A 45-days feeding trial was conducted on juvenile tiger shrimps Penaeus monodon of size 0.997±0.098 g with diets containing Mannan oligosaccharides (Mos) at three graded levels (0.1, 0.2 and 0.3%). Maximum weight gain (1.353 g) was achieved in shrimps fed with 0.3% Mos concentration, followed by 0.2% Mos (1.224 g). Best feed conversion ratio (FCR) of 2.406 was registered in 0.3% Mos groups. Results indicate that there was a significant difference (p<0.01) in weight gain and FCR among the treatments. However, no statistical differences were observed on the specific growth rate (SGR), mean feed intake and survival rate. Feeding trial was followed by a 10 days challenge study with Vibrio harveyi by intramuscular injection and white spot syndrome virus (WSSV) by feeding WSSV infected tissues. Significantly higher survival rate was observed in the shrimp groups fed with 0.3% Mos (66.67%) than the other treatments when challenged with V. harveyi. Tiger shrimps fed with 0.3% Mos challenged with WSSV showed a significantly higher survival rate (66.67%), followed by 0.2% Mos (50%), 0.1% Mos (25%) and control (25%) on day 5 post-challenge. However On day 10 post-challenge with WSSV, except in the groups fed with 0.3% Mos (16.67% survival), 100% mortality was noticed in all other diet groups. Therefore, it is concluded that dietary administration of Mos at 0.3% would enhance the growth and survival of tiger shrimp against V. harveyi. With respect to WSSV challenge, it appears that, though Mos at 0.3% had a positive effect on the shrimp, higher survival was not observed. Whether additional increment in Mos supplementation in the diet would positively affect the survival of tiger shrimps post-WSSV challenge, needs to be investigated further.
