Growth and survival of spiny lobster, Panulirus homarus fed fresh food and formulated diet

Abstract To date, lobster aquaculture relies on fresh food for feeding; however, the availability of fresh food is limited and its excessive use causes environmental degradation. Therefore, formulated diet is required to establish sustainable lobster aquaculture. Concerning this issue, this study was carried out to assess the growth and survival of spiny lobster Panulirus homarus fed fresh food and formulated diet. The study was conducted in a completely randomized design (CRD) with 3 groups of treatments and 3 replicates for each treatment. Feeding experiment was performed in a flow-through water system using 9 fibre tanks, 4000 L in volume. Each tank was stocked with 40 lobsters, with initial weight of 78.08 ± 0.22 g. Each group of lobsters was fed with fresh food (A), formulated diet (pellet) (B) and a combination of pellet and fresh food (C). The fresh food was a mixture of fish, crabs, shrimp and small mussel (3:1:1:1). Feeding experiment was done for 15 weeks. Results of the experiment showed that the highest specific growth rate of lobster was obtained from lobsters fed with the combination of pellet and fresh food (0.52 ± 0.02 %/day) and the lowest growth was resulted from lobsters fed formulated diet (0.16 ± 0.03 %/day). In contrast, the highest survival was achieved in lobsters fed formulated diet (51.67%). Whereas the lowest survival was found in lobsters fed fresh food (10%). This study indicated that good growth of lobster was resulted from feeding with formulated diet combined with fresh food, while good survival was supported by feeding with formulated diet.

Nutrient Contents

Kegiatan pembenihan lobster masih dikembangkan di Indonesia. Sintasan yang rendah dan pakan yang sesuai masih menjadi masalah utama dalam kegiatan pembenihan lobster. Artemia sebagai pakan utama diduga belum mencukupi kebutuhan nutrisi larva lobster. Upaya pemberian bahan pengaya sebagai alternatif untuk meningkatkan nutrisi diharapkan dapat meningkatkan sintasan larva lobster. Pemberian bahan pengaya yang mengandung asam lemak dokosa heksanoid acid (DHA) ke Artemia dianggap penting bagi pertumbuhan dan sintasan pada krustasea. Tujuan penelitian ini untuk mengetahui performa larva lobster berdasarkan tingkat sintasan maupun perkembangan larva dengan pemberian pakan artemia yang diperkaya dengan DHA. Perlakuan yang diberikan meliputi Artemia yang baru menetas (A), Artemia yang diperkaya dengan plankton Isochrysis galbana strain Tahiti konsentrasi (1-1,5 x 106 sel/mL) (B), DHA selco dosis 0,6 g/L (C), dan Artemia inkubasi 18 jam tanpa pengayaan (D). Pemeliharaan larva dilakukan pada bak 100 L dengan sistem air stagnan. Perkembangan larva yang mampu dicapai pada semua perlakuan adalah stadia-IIIa. Pemberian Artemia yang diperkaya dengan DHA selco menunjukkan hasil sintasan yang lebih baik pada pemeliharaan enam hari pertama namun tidak memberikan pengaruh yang signifikan. Pada masa pemeliharaan sampai 20 hari terjadi penurunan sintasan (SR) mencapai hanya 1%. Hal ini disebabkan adanya bakteri dan protozoa seperti jenis protozoa Zoothamnium sp. dan bakteri berfilamen teramati menempel pada tubuh larva sehingga mengganggu pergerakan dan kemampuan larva dalam menangkap mangsa. Berdasarkan penelitian ini maka penggunaan pakan Artemia yang diperkaya DHA Selco dapat menjadi alternatif pakan larva lobster namun tetap diperlukan kontrol kualitas air yang baik.Efforts to culture spiny lobster, Panulirus homarus larvae are still being developed in Indonesia. One of the main challenges in lobster hatcheries is to find an appropriate feed and improving larval survival. Artemia has been used as the main feed and considered to have insufficient nutritional ingredient for lobster larvae. Enrichment of feed to improve its nutrient contents is expected to increase the larval survival. DHA-enriched feed is considered essential for growth and survival of crustaceans. The aim of this study was to determine the survival and development of larvae fed with DHA-enriched Artemia. The treatments consisted of newly hatched Artemia (A), enriched Artemia with phytoplankton, Isochrysis galbana strain Tahiti at a density of 1-1.5 x 106 cells/mL (B), enriched Artemia with DHA selco at a dose of 0.6 g/L (C), and Artemia incubated for 18 hours without DHA enrichment (D). Each Artemia enrichment was performed for 18 hours. Larval rearing was carried out in a 00 L tank with static water system. The achieved larval developmental stage in all treatments was stage-IIIa. Administration of enriched Artemia with DHA selco showed a better larval survival during the first six days of larval rearing. But, it did not give any significant effect. The survival was then decreased to only 1% on day-20. This was due to the presence of bacteria and protozoa which decreased water quality. Protozoa Zoothamnium sp. and filamentous bacteria were observed attaching to the body of the larvae, disrupting the movement and ability of larvae in capturing prey. Based on this research, the use of Artemia enriched with DHA selco as an alternative for lobster larvae feed, but better water quality control is still needed.

Ikan gabus Channa striata merupakan salah satu komoditas ikan air tawar yang memiliki nilai ekonomis tinggi. Kendala dalam pengembangan budidaya ikan gabus adalah tingginya tingkat kematian pada stadia pemeliharaan larva. Tingginya kematian pada stadia larva karena kecukupan jumlah pakan dan nutrisi pakan awal yang tidak optimum. Tujuan percobaan adalah menentukan frekuensi pemberian Moina sp. yang tepat sebagai pakan awal pada pemeliharaan larva ikan gabus pada sistem air hijau (dengan menambahkan Chlorella sp.). Penelitian dirancang dengan rancangan acak lengkap. Perlakuan yang diberikan adalah frekuensi pemberian Moina sp. per hari sebagai pakan awal: A. enam kali tanpa pemberian Chlorella sp. (kontrol), B. enam kali + Chlorella sp., C. empat kali + Chlorella sp., dan D. dua kali + Chlorella sp. Hasil penelitian menunjukkan pemberian pakan awal dari jenis Moina sp. pada pemeliharan larva ikan gabus pada sistem air hijau dengan frekuensi pemberian dua, empat, dan enam kali dalam sehari memberikan performa sintasan (93,42%-94,29%) dan pertumbuhan tidak berbeda secara nyata (P>0,05). Frekuensi pemberian Moina sp. sebanyak dua kali sehari merupakan perlakuan yang efektif untuk sintasan dan pertumbuhan larva ikan gabus pada pemeliharaan dengan sistem air hijau.Snakehead fish Channa striata is one of the highly-valued freshwater fish commodity. However, its aquaculture development is hampered by a high mortality during larval stage rearing. This high mortality is suspected to be caused by insufficient quantity and quality of food. The purpose of this study was to determine the appropriate feeding frequency using Moina sp. as an initial food for snakehead fish larvae reared in a green water system (Chlorella sp.). A completely randomized design was arranged for this experiment where the treatments consisted of different feeding frequencies of Moina sp. given to the larvae as follows: A) six times a day without the addition of Chlorella sp. (control); B) six times a day with the addition of Chlorella sp.; C) four times a day with the addition of Chlorella sp.; and D) two times a day with the addition of Chlorella sp. The results of the experiment showed that the survival rate (93.42%- 94.29%) and growth of the larvae reared in the green water system with were not significantly different (P>0.05). However, this study suggested that feeding frequency of two times per day was sufficient to support an optimum growth and survival of snakehead larvae reared in a green water system.

Nursery of juvenile lobsters in the coastal area was attempted but survival was very low with unknown causes of mortality. The study determined whether communal or individualized houses affect the growth and survival of small and big juvenile lobsters after 60 days nursery culture in the laboratory. Four (4) treatments with four (4) replicates were identified in Completely Randomized Design (CRD) and these were small juvenile lobsters in communal tank (T1), small juvenile lobsters in individualized tank (T2), big juvenile lobsters in communal tank (T3) and big juvenile lobsters in individualized tank (T4). Results showed that communal tank for big juveniles attained significantly (P<0.05) highest weight increment of 5.31±1.66 g compared to individualized house for both sizes of lobsters (2.15±1.45 g and 0.68±0.49 g) and communal tank for small lobsters of 1.26±0.97 g. However, survival rate was very low in all treatments with communal tank obtained the highest survival of 45.75±8.50% with no significant difference among individualized tanks for both sizes of lobsters (29.00±20.93% and 20.75±15.76%) and communal tank for small lobsters (20.92±15.93%). Thus, communal tank is better than individualized tank in the nursery, particularly, for big juvenile lobsters but some aspects of the nursery may be improved to increase higher survival rate.

Background: Plants face different abiotic stresses such as salinity that affect their normal development, growth and survival. Forage pea is an important legume crop for herbage production in ruminants. Its agronomy requires high levels of irrigation and fertilization. This study aimed to evaluate the effect of salinity on seedling root system development in forage pea under semi-hydroponics conditions.Methods: Different treatment of NaCl doses (0, 50, 100, 150, 200, 250 and 300 mM) on root architecture was investigated in two different forage pea cultivars (Livioletta and Ulubatlý) with contrasting root structures under controlled conditions. The experimental design was completely randomized design with three replications and nine plants per replication.Result: Salinity affects root and shoot development differently on these cultivars. Despite the salinity, Livioletta produced more shoot (0.71 g) and root biomass (0.30 g) compared to Ulubatlý (0.52 g and 0.25 g for Root and Shoot biomass, respectively) at 150 mM and all other salinity levels. Livioletta developed a better root system and tolerated salt to a higher dose than Ulubatlý. Understanding root system responses of forage pea cultivars may allow breeding and selecting salinity tolerant cultivars with better rooting potential.

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.

The aims of the study were to evaluate seedling growth and survival of Prunus africana provenances in awi highland based on ecological requirement of the tree. We measured survival and growth of three P.africana provenances seedlings found in Ethiopia (provenances sources namely: Gedeo, Jibat and Munnessa). Design of experiment with randomized complete block design (RCBD) with three replications. Seedlings planted at 2m, 2.5m and 3m distance between plants, plot, and blocks respectively. A plot size of 10mx10m and 25 plants are found per plot (0.01ha). We used ANOVA to test differences in survival, and growth among provenances over time. Results concluded that, provenances have no significant variation among in establishment rate, plant height and collar diameter growth. Of these provenances, Jibat was the first in establishment (56%), second in height (1.97m) and diameter (2.89cm). Gedeo was stood first in height (2.30m) but second in establishment rate (52%) and thickness(3.45cm), but Munessa with very good growth in diameter(3.59cm) might be prefreed for bark extraction followed by Gedeo, last in height (1.75m),but established second (52%). Contrary to expectations, seedlings were still at substantial risk of mortality ≥3 years after planting. Probably the plants survival rate and growth probably affected by altitude, soil water potential, light exposure, and wild animal presence in the surrounding. In steep slope sites, canopy shade, existing weed vegetation as well as wild animals such as apes is unlikely to enhance seedling survival after planting. Our results suggest that seedling mean growth increased with 0.008mm thickness and 0.41mm per day while 2.8mm thickness and 146.8mm tall increment recorded in 2560meter elevated high land or injibara with mean value of 18.5°C and rain fall is 1300mm.
