Results of study showed that yolk egg utilization efficiency of embryos and larvae incubated at 30 o C was 73.70% and 0,18%, respectively, and no different with that of room and 27 o C incubation temperatures. Hatching rate of eggs incubated at 30 o C (84.75%) was also same with that of other treatments. However, incubation time to hatch (27.41 hours) was shorter than that of other treatments. The growth rate by length of larvae (2.16%) and survival rate (75.28%) incubated at 30 o C was also higher compared with that of other treatments. Thus, in general, optimum temperature for egg hatching and larval rearing of maanvis was 30 o C.

Di samping itu, Indonesia memiliki keanekaragaman sekitar 45% species ikan dunia yang tersebar di setiap perairan baik di laut maupun di daratan. Namun, dari sekian banyak species tersebut belum banyak yang dikembangkan untuk kegiatan usaha budidaya (akuakultur). Dengan demikian peluang pengembangan akuakultur Indonesia di masa depan dapat memberikan hasil yang menjanjikan. Aquaculture Indonesia Weblog (2006) mencatat bahwa komoditas perikanan unggulan yang dapat dikembangkan untuk kegiatan akuakultur di Indonesia, meliputi crustacea, ikan bersirip (fin fish), rumput laut echinodermata, moluska dan lain 1 . Dalam rangka pembangunan akuakultur di Indonesia dengan tujuan untuk meningkatkan nilai gizi dan kesejahteraan sosial ekonomi bagi masyarakat, pemerintah telah berusaha mengarahkan para pembudidaya dan pengusaha (investor) untuk memanfaatkan sumberdaya lingkungan perairan yang ada, baik itu perairan umum, pesisir pantai dan laut sebagai sarana untuk meningkatkan produksi perikanan. Arahan yang disertai dengan penyediaan sarana dan prasarana yang memadai tersebut telah memacu perkembangan akuakultur yang pesat di antaranya budidaya udang (Peneaus monodon) di tambak air payau, dan ikan Mas (Cyprinus carpio) di waduk dan danau air tawar pada beberapa tempat di Indonesia 2 . Perkembangan budidaya intensif di dua ekosistem perairan yang berbeda tersebut terbukti sangat positif pengaruhnya bagi perekonomian lokal dan nasional; bahkan budidaya intensif di tambak, khususnya udang pernah mengantarkan Indonesia menjadi produsen terbesar ke-2 di dunia setelah China serta penyumbang devisa ke-4 pada sektor non-migas. Krustase yang terdiri dari berbagai macam udang-udangan, seperti windu, vanamei, galah, putih, lobster, kepiting, rajungan dan cherax yang telah 1

Water and plankton samples were collected from fish ponds (tambak), Kali Buaya channel and sea. Questionnaires were administered to 25 farmers. Results of water quality analyses showed that Holtekamp coastal water is characterized with higher concentration of BOD5 (Biological oxygen demand), N-total, COD (chemical oxygen demand) and TOM (total organic matter) 4.96 mg/l, 4.19 mg/l, 33.53 mg/l, and 22.18 mg/l, turbidity (7.02 NTU) and TSS (total suspended solids) 201.67 mg/l were higher in Kali Buaya chanal and PO4-P (2.08) in fishpond. The carrying capacity of coastal water is 10.452.915 m3 and a maximum of effluents 104.529 m3, respectively.Key Words: Ponds; Effluents; Water quality; Carrying capacity; Holtekamp

In : Herlinda S et al . ( Eds .), Prosiding Seminar Nasional Lahan Suboptimal 2019, Palembang 4-5 September 2019. pp. 9-19. Palembang: Unsri Press. Aquaculture or fish farming is a fisheries production system that has an important role in providing food now and especially in the future, together with agriculture and animal husbandry in the agrimaritime context. The system that can apply in freshwater on land, brackish water and sea waters, including suboptimal land area, is predicted will supprass the production of capture fisheries in providing fish for the community. In line with the development of industry 4.0, aquaculture began and is developing an instrumentation, integration and automation strategy that leads to smart farming, both on-farm and off-farm levels, as aquaculture 4.0. At the on-farm level, aquaculture 4.0 can apply to the entire production process since site selection, pond or...

The 1 day old larvae (day after hatching), with 3,37-3,97 mm length and 0,62-0,79 mg weight, were reared in aquarium 60x50x40 cm with stocking density of 20 fish/l. Larvae were fed Artemia dan tubificid worms 2-8 dan 7-15 days after hatching (dAH), respectively (schedule I); 2-6 and 5-15 dAH (schedule II); and 2-4 and 5-15 dAH (schedule III). Chlorella was ready to eat by larvae at the entirely rearing. For enzyme assay, larvae were sampled from each aquarium at stages of 1, 2, 3, 5, 7, 10 and 15 dAH. Protease and lipase activity were detected in digestive tract of 1 dAH larvae. Digestive enzymes development have a similar pattern in larvae for all feeding schedules. Protease activity decreased with the increasing of age until 3 dAH, then increased until the larvae reached 7 dAH, and sharply decreased until 10 dAH and then slowly decreased thereafter. Lipase activity tended to increase slowly with age up to 3 dAH, and increased sharply until 5 dAH, and then decreased sharply until 7 dAH before decreased again up to the end of rearing. Amylase activity in larvae increased slowly with the increasing of age up to 5 dAH, then increased sharply until 7 dAH, and decreased thereafter. In dimly lighted larvae, amylase activity decreased before increased up to 12 d AH, then decreased thereafter. The amount of food organisms in larval gut, body weight and length, and survival rate of larvae were also measured and discussed.
