Abstract

Striped snakehead is one of the potential local species, however, its production in Indonesia still comes from capture fisheries. Over exploitation had decrease the population in nature. Domestication is one of promising tool to solve the problems faced. In order to breed the domesticated species, the information of their reproduction was needed. This study aimed to describe relationship between length and weight, length and fecundity, weight – fecundity and gonad weight – fecundity of the striped snakehead from West Java. A total of 19 mature female specimens were collected from Parung (Bogor), and seven mature female specimens were collected from Babelan (Bekasi). The results showed that the determinant value (R2), the first for Parung and the second for Babelan, between weight and fecundity were 0.599 and 0.843, length-fecundity were 0.541 and 0.841; gonad weight – fecundity 1.00 and 0.846 Gonadosomatic Index (GSI) ranged from 0.67 to 9.94% and 2.03 to 8.17%. Gonad Index ranged from 6.17 – 76.73 and 18.48 – 76.77, respectively. The data indicated that growth pattern was allometric. Length and body weight has linear relationship with gonads and fecundity. Fecundity has higher correlation to the weight rather than length. Gonad weight and fecundity has a strong relationship.

Abstract

The aim of this research was to determine the optimum percentage of glycerol addition into the diets of  Nile Tilapia (Oreochromis niloticus) on growth performance, feed convertion ratio, and survival rate. The research was conducted using 15 aquaria with the size of 60 x 50 x 45 cm3, each containing 25 O. niloticus with average initial weight of 4.63 ± 0.15 g. The experiment was conducted using a complete random design with five treatments and three replications. Isonitrogenous (31%) and isocaloric (17 MJ.kg-1) diets were provided for 60 days of rearing period. Five diets were formulated with glycerol content of 0% (G0); 5% (G5); 10% (G10); 15% (G15), and 20% (G20). Fish were fed twice daily with experimental diet at satiation level. The result showed that addition of 10% glycerol in the diet (G10) presented the highest values for weight gain (105.85 ± 0.40%), specific growth rate (3.44 ± 0.01%), protein retention (27.75 ± 0.02%), protein efficiency ratio (2.53 ± 0.15%), lipid retention (60.44 ± 0.03%), and feed convertion ratio (1.59 ± 0.01%) (P < 0.05). Survival rate was not affected by dietary containing glycerol (P > 0.05). Therefore, addition of 10% glycerol into the diet gave a significant increase on growth performance and feed convertion ratio without adverse effect on survival rate of Nile Tilapia.

Abstract

The production of good quality seed for culture purpose begins with proper attention to the nutritional requirements of the parental broodstock. The objective of this research was to know the level of lipid in broodstock feed to reach good seed production.The experiment was conducted in concrete ponds located at Research Instalation for Aquaculture Environment and Toxicology,Cibalagung, Bogor. Broodstock with average individual body weight of 420.8 ± 72.10 g were cultured in concrete pond 3.5 x 2.53x 0.8 m with stocking density of 15 fish/pond. Pelleted fish with 35% protein content and different lipid level of 4, 6, 8, 10, and 12 % were given with daily ratio 2 % of body weight. Gonadosomatic index, ovosomatic index; the weight, the number and the diameter of egg; fertilization rate, hatching rate, percentage of larva produced and daily growth rate and survival rate of 21 days old seed were observed. The result showed that there were no significant difference (P>0.05) among treatments for all parameters except for the diameter of the egg. The result showed that all of the broodstock were matured in three months.Gonadosomatic index were ranged between 13.69-16.65%, ovosomatic index: 11.26-14.62%. The weight of the egg varied from 1.45-1.69 mg/egg with the diameter in between 1.37-1.66 mm. The number of eggs per kg broodstock varied from 74,473-88,787 with fertilization rate of : 67.15-93.29%, and hatching rate were ranged from 88.33%-96.62%. The feed with 8% lipid level showed the highest value of gonadosomatic index (16.65%), fertilization rate (93.29%), percentage of larva produced (90.14%), egg weight (1.69 mg) and egg diameter (1.66 mm). Average daily growth rate of the 21 days old offsprings was 18.12%-19.25% with survival rate of 60.25%-75.50%. The feed with 8% lipid level tends to give the best effect on the reproduction parameters and the performances of the seed.

Abstract

ABSTRACTSnakehead Channa striata is a local specific fish species and has high economic value. Until now the production of snakehead still reelies on the catch of nature because cultivation of snakehead is still underdeveloped. The main constraint in snakehead fish farming is high mortality on snakehead juvenile rearing phase. This study was conducted to determine the best stocking density on snakehead juvenile rearing to achieve optimal production. The treatments used in this study were stocking density of 1 juvenile/L, 2 juveniles/L, and 3 juveniles/L. Snakehead juveniles with a length of 3.41 ± 0.39 cm and weight 0.28 ± 0.07 g, were reared for 42 days in the aquarium sized 40×40×40 cm with a volume of 40 L. Fishes were fed by bloodworms in ad libitum method. The result showed that the treatments did not affect the survival, growth and the ratio of RNA/DNA of snakehead juvenile. Survival of juvenile snakehead ranged 92.5‒94.58% (P>0.05). The result of water quality measurement showed that it was on optimum condition to supporting snakehead growth at 3 juveniles/L stocking density. Furthermore, recirculation can be use to maintenance water quality for optimum condition. Thus, the rearing of snakehead fish juvenile in the recirculation system can use a stocking density of 3 juveniles/L, and the recirculation system could maintain the water quality in good condition. Keywords: growth, recirculation system, snakehead fish, stocking density, survival rate  ABSTRAK Ikan gabus Channa striata merupakan ikan spesifik lokal dan mempunyai nilai ekonomis tinggi. Sampai saat ini produksi ikan gabus masih mengandalkan tangkapan dari alam karena kegiatan budidaya ikan gabus masih belum banyak berkembang. Kendala utama dalam budidaya ikan gabus adalah tingginya mortalitas pada fase pemeliharaan benih. Penelitian ini dilakukan untuk menentukan padat tebar terbaik dalam upaya memperoleh pertumbuhan dan sintasan terbaik. Perlakuan yang digunakan dalam penelitian ini adalah padat tebar 1 ekor/L, 2 ekor/L, dan 3 ekor/L. Benih ikan gabus dengan panjang rata-rata 3,41± 0,39 cm dan bobot rata-rata 0,28 ± 0,07 g dipelihara selama 42 hari di dalam akuarium berukuran 40×40×40 cm dengan volume air 40 L. Benih ikan gabus diberikan pakan berupa cacing sutera secara ad libitum. Hasil penelitian menunjukkan bahwa penggunaan padat penebaran yang berbeda tidak memengaruhi sintasan dan pertumbuhan dan rasio RNA/DNA benih ikan gabus (P>0,05). Sintasan benih ikan gabus pada akhir pemeliharaan berkisar antara 92,5‒94,58%. Hasil pengukuran terhadap kualitas air pada kepadatan 3 ekor/L masih dalam kondisi optimum untuk mendukung pertumbuhan benih ikan gabus sehingga sistem resirkulasi yang digunakan dapat mempertahankan kualitas air dengan baik. Hasil penelitian menunjukkan pemeliharaan benih ikan gabus pada sistem resirkulasi sebaiknya menggunakan padat tebar 3 ekor/L dan sistem resirkulasi dapat mempertahankan kualitas air dalam kondisi baik. Kata kunci: ikan gabus, pertumbuhan, padat tebar, sintasan, sistem resirkulasi.

Abstract

Penelitian ini bertujuan untuk mengevaluasi pengaruh suplementasi glutamin terhadap pertumbuhan dan aktivitas antioksidan pada ikan Torsoro (Tor soro). Ikan uji yang digunakan adalah juvenil ikan dengan berat awal rata-rata 5,21 ± 0,04 g. Perlakuan yang diberikan terdiri atas suplementasi glutamin bebas dengan dosis yang berbeda (0; 0,5; 1,0; 1,5; dan 2%) dan alanil-glutamin (0,84; 1,67; 2,51; dan 3,35%) pada pakan, setiap perlakuan memiliki lima kali ulangan. Perlakuan pakan diberikan tiga kali sehari sekenyangnya. Ikan uji dipelihara selama 60 hari. Parameter yang diamati meliputi performa pertumbuhan, pemanfaatan nutrisi, indeks biologis, dan aktivitas antioksidan. Hasil penelitian menunjukkan bahwa pakan yang disuplementasi glutamin bebas berpengaruh nyata (p<0,05) terhadap performa pertumbuhan, pemanfaatan nutrisi, indeks biologis, dan aktivitas antioksidan ikan uji. Hasil uji lebih lanjut menunjukkan bahwa suplementasi alanil-glutamin dalam pakan sebesar 2,51% memberikan hasil terbaik terhadap bobot akhir, laju pertumbuhan spesifik, retensi protein, rasio efisiensi protein, konversi pakan, rasio viseral somatik, rasio panjang usus, aktivitas superoksida dismutase, glutation peroksidase, dan katalase pada ikan Torsoro. Berdasarkan evaluasi keseluruhan terhadap parameter yang diamati, penelitian ini menunjukkan bahwa suplementasi alanil-glutamin dalam pakan pada tingkat 2,51% mampu meningkatkan kinerja pertumbuhan, pemanfaatan nutrisi, indeks biologis, dan aktivitas antioksidan pada ikan Torsoro.This study aimed to evaluate the effects of glutamine supplementation on the growth of and antioxidant activity in Torsoro fish (Tor soro). The test fish used were Torsoro fish juveniles with an average initial weight of 5.21 ± 0.04 g. The treatments consisted of different supplementation levels of free glutamine (0; 0.5; 1.0; 1.5; and 2%) and alanyl-glutamine (0.84; 1.67; 2.51; and 3.35%) in feed, where each treatment had five replicates. The feed treatments were given three times a day ad satiation. The experimental fish were reared for 60 days. The parameters observed included growth performance, nutrient utilization, biological indices, and antioxidant activity. The results showed that free glutamine-supplemented feed significantly affects (p<0.05) the growth performance, nutrient utilization, biological indices, and antioxidant activity of the tested fish. Further test results showed that alanyl glutamine supplementation in feed at 2.51% produced the best results on the final weight, specific growth rate, protein retention, protein efficiency ratio, feed conversion, somatic visceral ratio, intestine length ratio, superoxide dismutase, glutathione peroxidase, and catalase activities of Torsoro fish. Based on the overall achievement of the observed parameters, this study determines that alanyl-glutamine supplementation in feed at 2.51% improves the growth performance, nutrient utilization, biological indices, and antioxidant activity of  Torsoro fish.
