Abstract

The slow growth of the Java barb (Puntius javanicus Bleeker, 1855) fingerlings is due to the feeding of plant-based protein which is usually lack of lysine.  The lack of it, can hinder the feed efficiency and growth. The best way to solve the problem is by adding lysine in the diet. The objectives of the study were to determine optimal needs of lysine to increase feed efficiency, growth, and nutrient contents of Java barb.  The fish samples were fingerlings of Java barb which weighed from 3.26 to 3.78 g-1 fish. The feed comprised 30% isoprotein and 262 Kcal isoenergy supplemented with lysine amino acid.  The dosages of the lysine in the diet were 1.25% (A1), 1.5% (A2), 1.75% (A3), 2.0% (A4), 2.25% (A5), and 2.5% (A6) of dried diets. The parameters observed were relative growth rate (RGR), apparent digestibility coefficients of protein (ADCp), efficiency of feed usage (EFU), feed conversion ratio (FCR), protein efficiency ratio (PER), survival rate (SR), hepatosomalic index (HSI), viscerosomatic index (VSI) and nutrient contents of Java barb. The results of the study disclosed that the enrichment of lysine into the diet increased the feed utilization, the growth and the nutrient contents of Java barb.  The needs of lysine for Java Barb (Puntius javanicus) fingerlings to optimize feed efficiency, growth, and nutrition contents ranged from 1.58% to-1.70% dried diet (5.3 to 5.6 % of protein diet).

Abstract

The shrimp culture is collapsing at Jepara coast. Several internal and external reasons have  caused this and are needed to be handled seriously. An alternative solution should be conducted and applied without delay. Recent Existing condition of the shrimp culture at Jepara Coast is  experiencing a tremendous decline in the last five years. There are four category of internal  factors determinant which shows this decline:  the  development  of  shrimp  culture production,  the  development  of  shrimp culture  available cultivation area, shrimp culture number of units,  and the development of the farmers’ internal revenue. The degradation of the shrimp culture at Jepara coast is mainly caused by environmental and managerial reasons. The environment is no longer supporting the shrimp culture at Jepara coast and to overcome this, a  relocation  or  re-zonation  should  be  applied.  As  alternative  solution,  to regain  the  Jepara region’s aquaculture potencies, a new species can be introduced and applied. In order to develop new species and to sustain its productivity, the new species should have some characteristics as  follows: easy to culture, invulnerable to disease, high market demand, high market price, short cultivation period, low production cost, and able to adapt with unfortunate water quality.   Key words : Shrimp culture condition, Jepara coast

Abstract

Vannamei shrimp (Litopenaeus vannamei) is one of the leading fishery products of the fisheries sector. The problem that is often found in the failure of vannamei shrimp productions is the high level of mortality due to the nature of cannibalism during molting. One solution to minimize the cannibalism of vannamei shrimp is to provide tryptophan supplements in a feed. Tryptophan is a type of essential amino acid that serves as a precursor for serotonin biosynthesis. This study aims to determine the effect and optimal dose of tryptophan added to feed to reduce cannibalism and growth of vannamei shrimp. The test fish used in this study were vannamei shrimp with an average weight of 0,81 ± 0,26 g/individual.  This study used an experimental method, a completely randomized design (CRD) consisting of 4 treatments and three replications. The test feed used in this study was artificial feed with a protein content of 38% plus tryptophan according to treatments A (0%/kg feed), B (0.75%/kg feed), C (1.5%/kg feed), and D (2.25%/kg feed). The results showed that the addition of Tryptophan in the feed had a noticeable effect (P<0,05) on cannibalism levels, survival, and molting rates but had no significant effect (P>0,05) on absolute weight growth, specific growth rates, efficiency ratios protein and efficiency feed utilization of vannamei shrimp. The best dose of tryptophan addition in feed to lower the rate of vannamei shrimp cannibalism in this study was 2,25%, capable of producing a cannibalism rate of 13,33%. Udang vaname (Litopenaeus vannamei) merupakan salah satu produk perikanan unggulan sektor perikanan. Permasalahan yang sering ditemukan dalam kegagalan produksi udang vaname adalah tingginya tingkat mortalitas karena adanya sifat kanibalisme pada saat terjadi molting. Solusi untuk meminimalisir kanibalisme udang vaname adalah dengan memberi suplemasi asam amino pada pakan, salah satunya adalah triptofan. Triptofan merupakan salah satu jenis asam amino esensial yang berfungsi sebagai prekursor untuk biosintesis serotonin. Penelitian ini bertujuan untuk mengkaji pengaruh dan dosis optimal triptofan yang ditambahkan ke dalam pakan untuk menurunkan tingkat kanibalisme dan pertumbuhan udang vaname. Ikan uji yang digunakan pada penelitian ini adalah udang vaname dengan bobot rata-rata 0,81±0,26 g/ekor. Penelitian ini menggunakan metode eksperimen, rancangan acak lengkap (RAL) yang terdiri atas 4 perlakuan dan 3 kali ulangan. Pakan uji yang digunakan dalam penelitian ini adalah pakan buatan dengan kandungan protein 38% ditambah triptofan sesuai perlakuan yaitu : A (0%/kg pakan), B (0,75%/kg pakan, C (1,5%/kg pakan), dan D (2,25%/kg pakan). Hasil penelitian menunjukkan bahwa penambahan triptofan dalam pakan berpengaruh nyata (P<0,05) terhadap tingkat kanibalisme, kelulushidupan dan tingkat molting, namun tidak berpengaruh nyata (P>0,05) terhadap pertumbuhan bobot mutlak, laju pertumbuhan spesifik, protein efisiensi rasio dan efisiensi pemanfaatan pakan. Dosis terbaik dari pemberian triptofan dalam pakan untuk menurunkan tingkat kanibalisme udang vaname dalam penelitian ini adalah 2,25%, mampu menghasilkan tingkat kanibalisme sebesar 13,33%.

Penelitian ini dilakukan pada bulan Maret sampai dengan April 2017 di Balai Benih Ikan (BBI) Boja, Kabupaten Kendal, Jawa Tengah. Penelitian ini dilakukan menggunakan metode eksperimen Rancangan Acak Lengkap (RAL) dengan 3 perlakuan dan 5 ulangan. Perlakuan dalam penelitian ini adalah perbedaan intensitas cahaya, perlakuan A dengan intensitas cahaya 0-5 lx, perlakuan B dengan intensitas cahaya 20±5 lx, dan perlakuan C dengan intensitas cahaya 50±5 lx. Variabel yang diamati meliputi pertumbuhan bobot mutlak (gram), laju pertumbuhan relatif (%/hari), kelulushidupan (%), dan kualitas air. Hasil penelitian menunjukkan bahwa perbedaan intensitas cahaya tidak berpengaruh nyata terhadap pertumbuhan bobot mutlak, laju pertumbuhan relatif, dan kelulushidupan benih ikan patin. Kualitas air pada media pemeliharaan berada pada rentang yang masih dapat ditoleransi benih ikan patin. Kisaran intensitas cahaya terbaik bagi performa pertumbuhan dan kelulushidupan benih ikan patin tidak ditemukan dalam penelitian ini, namun pertumbuhan bobot mutlak dan laju pertumbuhan relatif tertinggi ditunjukkan oleh perlakuan A (0-5 lx), sedangkan kelulushidupan tertinggi ditunjukkan oleh perlakuan C (50±5 lx). Catfish (Pangasius hypophthalmus) is one of the favourite consumed fishes for Indonesian. Proper fingerling culture will generate optimal growth performance and high survival rate. The purposes of this research are to understand the effect of various light intensity on growth performance and survival rate in catfish fingerling culture and to determine the best light intensity for catfish fingerlings culture. Materials and instruments used in this research namely catfish fingerlings, fish commercial foods, containers, fishnets, digital scale, aeration equipments, 5 watt LED lights, mulsa plastics as a cover to prevent light’s entrance from the outside, sufficient electrical instalations for a stable light intensity, lux meter to measure the light intensity, stationeries and water quality measuring instruments. The research was conducted in March to April 2017 at Balai Benih Ikan (BBI) Boja, Kendal Regency, Central Javaby using completely randomized design experimental method with 3 treatments and 5 repetition.

Abstract

The success of fish farming is largely determined by the availability of quality feed that not only contains protein that meets the needs of the fish, but also contains a complete amino acid profile. The problem faced by catfish farmers Sangkuriang Sido Makmur Tambaksari Village, Rowosari District, Kendal District, which is a partner of the community service activity of the Community Superior Commodity Strengthening (PKUM) scheme is the still low efficiency of feed utilization so that feed costs are high, almost 60% of the total production costs. This is because soybeans as a source of vegetable protein in feed have limited methionine amino acid content. One effort to overcome partner problems is to apply methionine amino acid supplementation in feed to improve feed quality. The method of community service activities of the PKUM scheme consists of several stages, namely socialization, training, application of technology, mentoring and evaluation, and sustainability. The purpose of this PKUM scheme community service activity is to assist partners in solving problems so that feed utilization efficiency increases, fish growth increases, feed costs decrease and partner income increases. From the results of the PKUM scheme community service activities, it shows that the increase in the efficient value of feed utilization is 75%, fish growth is 4.2%/day, feed costs decrease to 50% of the total production costs, Sangkurian catfish production increases to 2,050 kg/cultivation cycle and partner income increases to Rp.8,750.-00/cultivation cycle. The results of the PKUM scheme community service activities can be concluded that the application of methionine amino acid supplementation in feed can increase the efficiency of feed utilization, the growth of Sangkuriang catfish, reduce feed costs and increase the income of partner members
