Abstract

The worm Dendronereis pinnaticirris is used as feed of shrimp broodstock in a hatchery, mainly because of its availability in the local market, and its nutritional content required for improving gonad maturation and post larvae production. The important economic value of the worm and the increasing demand for feed in shrimp hatcheries have led to an intense exploitation that suppers its population and the sustainability of the whole estuarine ecosystem. The study, which represents the starting point of large-scale production of the polychaete worm by culture in the artificial system, shall be undertaken. Accordingly, a production study using D. pinnaticirris juvenile was carried out under controlled conditions fed with two different feed (feed contains mainly plant protein and animal protein, respectively), and kept in three different substrates (substrate consists of mud and 8.78%, 37.34%, 39.17% sand, respectively). The treatments were arranged according to randomized completely block design in 8 (eight) replicates. The survival rate, body weight increment and growth, oxygen consumption, proximate body chemical, and fatty acid contents were measured. The results showed that growth and oxygen consumption was significantly influenced by a substrate and feed type (P<0.05).  Worms on the mud substrate with 39.17% sand, and feed containing vegetable protein showed the highest oxygen consumption.  Survival rate and chemical body content were not significantly influenced by the type of substrate and feed (P<0.05). The protein content of the worm was 32.02-43.81%, while fat content was 2.41-9.89%. Twenty different fatty acids were identified in the worm of all treatment groups.

Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh penyapihan pakan mikroenkapsulasi ekstrak kasar maggot pada umur larva nila (Oreochromis niloticus) yang berbeda serta menentukan waktu penyapihan yang tepat. Analisis yang digunakan adalah Rancangan Acak Lengkap (RAL) dengan 4 perlakuan (kontrol atau tanpa penyapihan, penyapihan pada umur 9, 14 dan 19 hari) dan 4 ulangan. Variabel yang diamati yaitu, pertumbuhan mutlak (panjang dan berat), laju pertumbuhan spesifik (SGR) dan sintasan (SR). Hasil penelitian menunjukan pertumbuhan mutlak panjang berkisar 7.15 - 8.65 mm, pertumbuhan mutlak berat berkisar 0.046 - 0.084 g, SGR berkisar 5.633 - 7.352 % dan SR berkisar 64 - 76 %. Waktu penyapihan pakan berpengaruh terhadap pertumbuhan dan sintasan larva ikan nila (p0,05). Waktu penyapihan pakan terbaik terdapat pada usia larva 9 hari.

Abstract

A study entitled “Chilled Preservation of Spermatozoa Half-moon Strain Fighting Fish (Betta spendens) in Honey and Physiological NaCl”, was conducted to determine preserved spermatozoa motility and viability of Fighting Fish in honey and NaCl solutions, under chilling temperature (-250C). The study applied Completely Randomized Design (CRD) to examine three treatments, i.e aquadest, 0.09% NaCl and honey extenders, with quantuplicates. Data, being spermatozoa motility (%) and viability (time in second), were F-tested (ANOVA) and followed by LSD test (P<0.01). After storage of 7 days, the result showed that spermatozoa motility did not differ between treatments, however the viability of spermatozoa were significantly different (P<0.01). The highest viability was observed in sperm stored in extender Honey averaging 368.90±102.16 seconds, compared to the 0.09% NaCl extender (81.79±8.54 seconds), and aquadest (187.90±35.36 seconds). It was concluded that the Honey, NaCl 0.09% and aquadest as extenders could be used as preservation solution fighting fish spermatozoa. The best viability of spermatozoa was observed in honey extender.

Abstract

Answering higher challenge of occupational area along with smaller available job opportunities, it is needed business creation for the society based on local resources and science and technology. One of aquaculture activity that conducted was application of injected spawning technique among and rearing larvae of catfish. The objective of this activity, skill, and increase income also as a new economic activity for students in Farmer Group Mandiri Jaya, Sokaraja, Banyumas. Research method comprised of activities like transfer of knowledge, training, demonstration plot and application of production for 4 months. Evaluation of technology transfer activity viewed from questionnaire value, training and demonstration plot viewed from ability and of participant to produce seed and profit gained. Generally, knowledge and skill of participant was improved. However viewed from production yield was still varied Evaluasi kegiatan transfer teknologi dilihat dari nilai kuisioner , pelatihan dan percontohan dilihat dari kemampuan dan keterampilan penguasaan teknologi sedangkan aplikasi produksi adalah kemampuan peserta menghasilkan benih dan keuntungan yang diperoleh. Secara umum pengetahuan, keterampilan peserta meningkat. Namun ditinjau dari segi hasil produksi masih bervariasi.

Abstract

Osteochilus vittatus is a freshwater fish that needs to be developed because it tastes savory and can be used as a biocleaning agent. Research on the effect of supplementation of Spirulina platensis in nilem fish that is maintained in a biofloc system on digestive enzyme activity has never been done before. The objectives of this study were to determine the effect of S. platensis supplementation on Osteochilus vittatus digestive enzyme activity maintained in the biofloc system and to obtain the most optimum level of S. platensis supplementation in improving the  digestive enzymes activity. The study was conducted experimentally with Completely Randomized Design with four treatments and five replications. Osteochilus vittatus were fed with Spirulina platensis level of 0, 2, 4, and 6 g kg-1 for 56 days. Enzyme activity was measured on days 0 and 56 with three kinds of buffer solutions. Amylase and protease activity was analyzed using ANOVA with a confidence level of 95%. The results showed that the highest amylase activity in the liver was 4.764 ± 1.705 U mg-1 protein and proximal intestine was 2.328 ± 0.838 U mg-1 protein. The highest protease activity was found in the liver and proximal intestine with activity of 6.536 ± 0.911 U mg-1 protein and 6.207 ± 2.195 U mg-1protein. Spirulina platensis supplementation level of 6 g kg-1 feed is the most optimum level (p0.05). Cultivation of fish with S. platensis supplementation in feed can increase enzyme activity and the fish maintenance in biofloc systems can improve water quality.

Abstract

The purpose of this activity is to improve the competence of fish feed manufacturing and can increase fish sales production. The approach method carried out in this activity is a participatory Participatory Rural Appraisal (PRA) approach starting with a survey and problem identification, socialization and counseling training on making fish meal, training and direct technical guidance on making feed formulations, and assistance in making fish feed. The result of this dedication is that partners know the technology of making feed using available and abundant ingredients so as to reduce production expenditure in fish farming. Counseling and training activities in community service received good enthusiasm from members and partners of direct participants in making fish feed. The result of service activities is that partners gain knowledge and skills in making independent fish feed from waste and local raw materials. Making independent feed is able to increase production profits by reducing production costs incurred. The potential for developing activities can encourage productivity and provision of skills that can be disseminated to the wider community.
