The problems in culture of early juvenile phase of spiny lobster Panulirus homarus is low survival rate of the seed. One of strategies to improve production is using filtration system during nursery of spiny lobster. The aim of this study to evaluate differentation of physical filtration system on responsse stress and survival rate of juvenile P. homarus. Experimental design of this study consisted of four treatments and two replications. The treatments were using flow through system without protein skimmer and filter (K), filtration system with protein skimmer (SK), filtration system with top filter (F) and filtration system with combinations of protein skimmer and top filter (SKF). P. homarus with initial weight 0.18+0.01 g were cultured for 60 days with density 250 lobster/tank. During maintenance, P. homarus were fed trash fish with feeding rate 20% of body weight. Parameters of glucose hemolymph were evaluated to determine stress response. Stress response was determined at day 0, 6, 20 and 60. Parameters of survival rate were determined at the end of experiment. The result showed that the treatment of filtration system with combination of protein skimmer and top filter (SKF) decreased stress responsse by decreasing glucose hemolymph of juvenile P. homarus during maintenance. Survival rate also higher (P<0.05) in treatment SKF (33.2%) than other treatments. It is concluded that SKF was the best physical filtration system for juvenile period of spiny lobster P. homarus  Keywords: filtration system, glucose hemolymph, spiny lobster, survival rate

<p>Spiny lobster <em>Panulirus homarus </em>is susceptible to the color alteration in captivity, and it might affect on the market acceptance by the customers. On the other hand, <em>Spirulina</em> is known as carotenoids source that is required for pigmentation, growth performance and survival rate for spiny lobster. This study addressed the effect of <em>Spirulina</em> inclusion in the diet of juveniles <em>P. homarus</em> to minimize color alteration and improve growth performance. This study was performed in Aquaculture Laboratory of the Research and Development Division for Marine Bio Industry – Indonesian Institute of Sciences (LIPI), North Lombok, West Nusa Tenggara, Indonesia. There were three replicates of three formulated feeds (0%, 4% and 8% <em>Spirulina</em> inclusion) and one replicate of natural feed (minced trash fish, TF). Juveniles were individually weighed and photographed to determine growth performance and color alteration in 6 body parts on carapace and abdomen using HSV (hue, saturation, value) color quantification method. After 97 days rearing period, compared to the initial color, changing body color were detected in all body parts of <em>P. homarus</em> and made them look brighter. Moreover, the inclusion of <em>Spirulina</em> in the formulated diet did not affect on specific growth rate and weight gain of spiny lobster. However, the survival rate of spiny lobster in formulated diets were better than trash fish diet. In conclusion, although the inclusion of <em>Spirulina</em> in the formulated diet did not enhance either in pigmentation level or growth performance of spiny lobster, utilization of formulated diet in spiny lobster culture are potential to prevent alteration of body color and also the mortality of <em>P. homarus </em>during the rearing period.</p><p>Keywords: Spirulina, juvenile, Panulirus homarus, diet, color <br />Abstrak <br />Perubahan Warna dan Performa Pertumbuhan Juvenil Lobster Pasir (Panulirus homarus) yang diberi Pakan Buatan dengan Konsentrasi Spirulina Berbeda. Lobster pasir Panulirus homarus yang dibudidayakan rentan mengalami perubahan warna menjadi lebih pucat, sehingga dapat memengaruhi tingkat penerimaan konsumen terhadap produk tersebut di pasaran. Spirulina merupakan salah satu sumber karotenoid yang dibutuhkan lobster dalam proses pigmentasi, pertumbuhan dan kelangsungan hidup. Tujuan dari penelitian ini adalah untuk mengetahui pengaruh penambahan Spirulina dalam pakan buatan terhadap perubahan warna tubuh dan performa pertumbuhan pada juvenile lobster pasir. Penelitian dilakukan di Laboratorium Budidaya Balai Bio Industri Laut-LIPI, Lombok Utara, Nusa Tenggara Barat. Perlakuan penambahan tepung Spirulina dengan konsentrasi berbeda (0%, 4% dan 8%) pada pakan buatan dilakukan sebanyak tiga ulangan, sedangkan perlakuan pakan rucah sebagai kontrol dilakukan tanpa ulangan. Setiap biota uji ditimbang dan difoto untuk dapat diamati tingkat pertumbuhannya serta perubahan warna yang terjadi di enam bagian tubuhnya menggunakan metode kuantifikasi warna HSV (hue, saturation, value). Setelah 97 hari pemeliharaan, warna seluruh bagian tubuh lobster mengalami perubahan menjadi lebih cerah dibandingkan warna awal juvenil. Jika dibandingkan dengan perlakuan ikan rucah, perlakuan pakan dengan tambahan Spirulina berhasil meningkatkan rasio kelulushidupan namun tidak memengaruhi laju pertumbuhan spesifik serta pertambahan berat tubuh biota uji. Meskipun penambahan Spirulina tidak memberikan pengaruh yang signifikan terhadap pigmentasi dan pertumbuhan, penggunaan pakan buatan dalam budidaya lobster pasir memiliki potensi yang besar dalam mencegah perubahan warna dan mengurangi tingkat kematian selama pemeliharaan.

Kelp habitats are in decline in many temperate coastal regions of the world due to climate change and expansion of populations of grazing urchins. The loss of kelp habitat may influence the vulnerability to predators of the juveniles of commercially important species. In this study relative predation rates for kelp versus barren reef habitat were measured for early juvenile Australasian spiny lobster, Jasus edwardsii (Hutton, 1875), on the northeastern coast of New Zealand using tethering methods. Variation in assemblages of predators over small spatial scales appeared to be more important for determining the relative predation of lobsters, regardless of habitat type. Therefore, the assessment of relative predation risk to early juvenile lobsters between kelp and barren habitats will require more extensive sampling at a small spatial scale, as well as a specific focus on sampling during crepuscular and nocturnal periods when these lobsters are most at risk of predation.

Instar 1, 3, 5, and 7 phyllosomas of the spiny lobsterJasus verreauxi were reared individually at one of four temperatures (18, 21, 24, and 27C) and fed low, medium, or high rations of 2- to 3-mm Artemia salina. An increase in the temperature reduced the intermoult period for all instars tested, but only the instar 5 phyllosomas showed any significant differences in postmoult size with temperature; those at 18C were smaller. Phyllosomas reared at 18C ate fewer Artemia each day than did those at the higher temperatures, but instars 3 and 5 at 18C consumed more in total over the intermoult period. Survival for all instars tested was lowest at 18C. Increasing the food rations affected the growth and survival of instar 5 and 7 phyllosomas; those fed at the lower rations took longer to moult and had a smaller growth increment. For all instars tested, the feeding rate and total consumption increased with food ration.

Laju pertumbuhan dan tingkat reproduksi yang tinggi merupakan karakteristik unggul yang dimiliki ikan nila sebagai komoditi budidaya. Tingkat reproduksi yang tinggi menyebabkan terjadinya pematangan gonad sebelum mencapai ukuran produksi dimana hal tersebut dapat merugikan pembudidaya, karena saat ikan mengalami matang gonad energi hasil asimilasi pakan sebagain besar akan dialokasikan untuk perkembangan gonad dan menghambat pertumbuhan somatik. Pemanfaatan senyawa aktif dari bahan alami biji pepaya dapat menjadi solusi untuk meningkatkan pertumbuhan ikan yang dibudidayakan sekaligus menjaga keamanan pangan dan konsumen. Penelitian ini bertujuan untuk mengetahui pemanfaatan tepung biji pepaya terhadap respons pertumbuhan dan tingkat kelangsungan hidup ikan nila. Ikan nila diberi perlakuan dengan lima dosis tepung biji pepaya berbeda (0, 1, 3, 5 dan 7 g/kg pakan) secara oral berdasarkan feeding rate 5% dengan tiga ulangan selama 30 hari pemeliharaan. Hasil penelitian menunjukkan dosis 5 g/kg meningkatkan pertumbuhan bobot tubuh tertinggi sebesar 547 g dibandingkan kontrol sebesar 406 g. Sejalan dengan pertumbuhan bobot tubuh, dosis 5 g/kg menghasilkan tingkat kelangsungan hidup ikan nila sebesar 100% dibandingkan kontrol sebesar 66%. Dari hasil yang diperoleh dapat disimpulkan bahwa tepung biji pepaya dengan dosis 5 g/kg pakan dapat meningkatkan pertumbuhan dan tingkat kelangsungan hidup ikan nila selama 30 hariHigh growth rate and high reproductive cycle are some economical triats on nile tilapia. This is a setback for nile tilapia culture because when the fish reach gonad maturity before reach market size, all the energy demand will flow to reproduction and can cause stunt growth. The utilization of natural compound from papaya seeds can be a solution to enhance growth of farmed nile tilapia and for consumer and food safety. This research aim to know how papaya seed powder can enhance growth and survival rate of nile tilapia. This research conducted into five groups of 5 papaya seeds powder dosage (0, 1, 3, 5 and 7 g/kg) that feed orally to the treatment fishes. Result showed the fishes feed with 5 g/kg papaya seed experienced highest growth performance 547 g compare to control which is 406 g. Same as growth performance, survival rate shown that group feed with 5 g/kg papaya seed had 100% survival rate compare with control which is 66% during treatment periods. Base on this result, we can make conclusion that fish feed with 5 g/kg of papaya seed have a better growth performance and survival rate compare with control group for 30 days treatment periods

Substrate is a key factor for successful crayfish culture, and it can be used to increase the survival rate. The effects of substrate on the survival and growth ofAstacus leptodactylusEschscholtz, 1823 were evaluated in flow-through compartments, divided into three sections and with two different substrates, over a period of 90 days. The three treatments used in the study were: artificial ropes, small stones, and a control group that received no substrate. The survival rate was highest in the small-stones treatment group (77.3%) and was lowest in the without-substrate treatment group (41.3%), while the artificial-ropes group showed an intermediate value (65.3%). Total yield was lower in the control group, 22.46% (25.0 g) as compared to the small-stones treatment group, with 42.3% (51.3 g) and the artificial-ropes treatment with 35.51% (55.8 g). In addition, cheliped injuries were found in higher proportion in the group without cover, and the artificial ropes yielded better results compared to the small-stones and no-substrate group in regard of the growth-increase rate.

Transport in water is the most common method for achieving high survival rates when transporting cultured fish in China; yet, transport success relies on proper water quality and conditions. This research was designed to explore the effects of ascorbic acid and β-1,3-glucan on survival, physiological responses, and flesh quality of farmed tiger grouper (Epinephelus fuscoguttatus) during simulated transport. The transport water temperature for live tiger grouper was 15 °C, which had the highest survival rate, the lowest stress response, and metabolic rate, and this will reduce the susceptibility to diseases. It is stated that β-1,3-glucan influences the changes of cortisol content, heat shock protein 70, IL-1β, and IgM transcription levels during simulated transport. Rather than using ascorbic acid alone (the A-group), β-1,3-glucan (3.2 mg/L) in the presence of ascorbic acid (25 mg/L) can effectively reduce the increase of transport-induced serum cortisol content, heat shock protein 70, and IL-1β, but stimulated IgM. 25 mg/L ascorbic acid and 3.2 mg/L β-1,3-glucan had no obvious effect on the nutritional indexes and flavor of live tiger grouper; however, these can effectively reduce the stress response, improve the innate immune activity, and ensure a higher survival rate.
