Abstract

Non-specific immunities are the main defenses in the fish seed. One of the natural ingredients as a source of immunostimulants is Moringa oleifera. Moringa leaves contain flavonoids, alkaloids, terpenoids and saponins as immunostimulant agents. Immunostimulants are biological that can enhance the immune system. The purpose of this study was to determine the effect of Moringa leaf extract in increasing non-specific immunity in tilapia (Oreochromis niloticus) seeds infected by Aeromonas hydrophila. In giving Moringa leaf extract intramuscular injection of 0.1 mL/fish with concentrations of 50 mg, 75 mg, and 100 mg. In this research method, a completely randomized design (CRD) was used with 4 treatments and 3 replications, each aquarium containing 12 tilapia measuring 8-10 cm each. Feeding on tilapia is done every 3 times a day namely morning, afternoon, and evening. The parameters tested were leukocytes, differential leukocytes, erythrocytes, phagocytic activity, and index. The results showed that the administration of Moringa leaf’s extract injected into tilapia seed can increase non-specific immunity, which are total leukocytes, total erythrocytes, differential leukocytes, activity, and phagocytosis index.

Abstract

Sakatiga Village, located in Indralaya District, Ogan Ilir Regency, South Sumatra, has the potential to develop aquaculture. Problems often experienced by fish farmers in the village of Sakatiga include the high price of feed and the lack of public knowledge about local materials that can be used as raw material for fish feed. These problems can be overcome by making feed independently. The purpose of this activity is to evaluate the effectiveness of the utilization of local materials as a raw material for feed to an increase in the productivity of catfish (Clarias sp.) in Sakatiga village, Indralaya District, Ogan Ilir Regency, South Sumatra. The method used is counseling and discussion, training in making food and a demonstration plot using local materials as raw material for fish food and technical assistance by the team and assisted by students who carry out field practices at partner locations. Based on the results obtained indicate an increase in community knowledge about local materials that can be used as fish food and community motivation to make feed using local raw materials. Utilization of local raw materials as catfish feed yields an absolute weight and length growth of 9.94 g and 3.83 cm respectively, a daily growth rate of 2.21%/day, feed efficiency of 103.24% and survival of 97%.

Abstract

This study aims to determine the effect of the extender combination of dates and ringer lactate extracts on the quality of spermatozoa of some freshwater fish in the process of preserving spermatozoa. The process of sperm preservation depends on the nutrients provided by the extender material. Ringer lactate has been used as an extender in the process of preserving sperm which is useful as an energy provider. Other energy can be obtained from materials that contain fructose or glucose. Date palm juice is one ingredient that has a fructose and glucose content that is expected to help provide energy for sperm during the process of sperm preservation. In this study an experiment of sperm preservation of several freshwater fishes carp (Carassius auratus), Siamese catfish (Pangasius hypophthalmus), and Koi (Cyprinus carpio) using an extender made in combination from ringer lactate and date palm solution. This study used different concentrations of date extracts i.e. 0.5%, 1%, 2.5%, 2% used randomized group design with fish as group. The results showed that the average of the Siamese’s motility achieved the highest value (52,00%) while the highest average fertilization rate occurred on Carp spermatozoa with a value of 97,06%. Palm juice solution can provide nutrients to the spermatozoa during the preservation process because the juice of dates contains fructose and glucose so that preserved spermatozoa can still fertilize normally.

Abstract

This study was aimed to observe the effects of different cryoprotectants in embryo cryopreservation on damage and hatching rates of African catfish (Clarias gariepinus) embryo. The gastrula-staged embryos were treated 5% (v/v) solutions concentration of dimethyl sulfoxide (DMSO), propylene glycol (PG), honey, and combined cryoprotectants, respectively and preserved at temperatures of 4 and 0ºC for 30 min, 1 h, 2 h, 3 h, 4 h, 5 h, and 6 h, respectively. Thawing of embryos was conducted in freshwater at a temperature of 28ºC. Then, the embryos were incubated in the aquaria at 28ºC temperature. The result showed that the different cryoprotectants in gastrula-staged embryo cryopreservation affect damage and hatching rates of African catfish embryos at different length of preservation. The percentage of catfish embryo damage increases with different length of preservation and the storage temperature. A combination of DMSO-honey and PG-honey has the lowest damage percentage and the highest hatching rate of catfish embryo compared to other treatments (p<0.05).

Abstract

Omega-3 fatty acids (Alpha-linolenic acid) and omega-6 fatty acids (Linoleic acid) are a group of essential fatty acids. Essential fatty acids are fatty acids that cannot be synthesized by the body so that must be supplied from the diet. One of the sources of essential fatty acids is derived from fish oil. This study aims to determine the effect of Crude Fish Oil (CFO) in the feed to EPA and DHA content in penaeid shrimp meat. The research method used was a completely randomized design. The treatments used are the varying content of Crude Fish Oil (CFO), which are P0 (0%), P1 (2%), P2 (4%), P3 (6%), and P4 (8%). The results of the study showed significant differences (p <0.05) on the content of EPA and DHA in penaeid shrimp meat. The highest content of EPA and DHA found in P4 treatment (8%) and the lowest at P0 treatment (0%). The use of CFO in penaeid shrimp feed need further study related to the growth of shrimps and prawns reproductive cycle to increase the productivity of penaeid shrimp. CFO on feed should be used at a dose of 6%.

Abstract

Nowadays, the inclining of Asian clam market demand for supplying the seller Etak in some areas in Malaysia particularly Kelantan where etak had become the main concern due to the stock availability in the natural population was over-exploited. Thus, an effort to expedite the availability seed of Etak must be initiated to conserve the Asian clam population in their habitat. Until now, the information about production larvae is needed to begin the domestication process. The scientific goal aims to evaluate the best time to produce Asian clam larvae to supply the hatchery production process. To answer this question, the evaluation of broodstock conditioning adult Corbicula fluminea monthly during a year and this condition was compared into the fine sand sediment as well as no sediment. The results showed that the Asian clam adult pattern released larvae monthly during a year wherein the great number larvae were produced 22464 Ind/L totally in December and the produced larvae in Oct and Nov was almost similar with range 22350-22500 Ind/L. The condition index with fine sand sediment was 3.8419 % higher than the control treatment 3.5750 %. And last, the ingestion rate both treatment was 1.126 ± 0.534 μg/h and control treatment 1.609± 0.434 μg/h.

Abstract

Udang merupakan salah satu komoditas unggulan nasional dan memiliki nilai ekonomi yang tinggi. Produksi udang budidaya di Indonesia tahun 2012-2017 mengalami kenaikan secara signifikan. Meski mengalami kenaikan, masih terdapat masalah yang harus diatasi, salah satunya adalah penyakit yang disebabkan oleh parasit Enterocytozoon Hepatopenaei (EHP). Infeksi EHP mengganggu sel tubulus hepatopankreas. Lesi yang disebabkan oleh EHP dapat menjadi tempat pertumbuhan koloni Vibrio sehingga meningkatkan kemungkinan munculnya penyakit lain. Penelitian ini bertujuan untuk mengetahui keanekaragaman Vibrio pada udang terinfeksi EHP yang dianalisis dengan Enterobacterial Repetitive Intergenic Consensus Polymerase Chain Reaction (ERIC PCR). ERIC PCR dapat membedakan strain bakteri yang berkerabat dekat, prosedur kerja yang sederhana, cepat dan murah. Bakteri Vibrio diisolasi dari hepatopankreas, feses dan air udang terinfeksi EHP dan udang sehat (kontrol), dilanjutkan dengan ekstraksi DNA, ERIC PCR, elektroforesis dan konstruksi pohon filogenetik. Hasil penelitian menunjukkan bahwa jumlah bakteri Vibrio pada hepatopankreas, air dan feses udang terinfeksi EHP lebih tinggi dibandingkan dengan udang sehat. Udang terinfeksi EHP memiliki keanekaragaman Vibrio yang lebih rendah dari pada udang sehat. Hal ini menunjukkan adanya spesies Vibrio spesifik yang mendominasi pada udang terinfeksi EHP.

Abstract

The ornamental fish business is now an economic driver. The ocellaris clownfish (Amphiprion ocellaris Cuvier, 1830) is one of the leading commodities of marine ornamental fish that is in great demand, especially in foreign markets. One obstacle faced by farmers in determining the appropriate density for the ocellaris clownfish rearing stage. This study aimed to evaluate the effect of stocking density on production factors, which included survival rate, and growth rate of ocellaris clownfish. Three hundred fish were used as experimental fish with an average length of 23.00 ± 2.36 mm and a weight of 0.27 ± 0.02 gather study was conducted using 4 treatment tanks with a volume of 120 L with densities of 0.17, 0.37, 0.67, and 0.80 fish/L. Observations showed that the density of 0.37 fish per L (K2) gave the best results with a survival rate of 98.18%. For the SGR parameter, the highest value was 1.14% per day in the K1 treatment. This indicated that the stocking density has a relationship with the factor of production in rearing ocellaris clownfish in the recirculation system.

Abstract

Caulerpa is one of the seaweed that grows naturally in Indonesian waters such as those in Mandangin Island. This study aimed to identify Caulerpa sp. based on molecular analysis using certain genetic markers. This research is expected to provide information on the identification of macroalgae from Indonesia waters, especially Mandangin Island, Madura with the use of molecular analysis based on 18SrRNA primers. The two green seaweed samples from the Caulerpa genus in this study were successfully analyzed using 18SrRNA primers. The BLAST results of samples 1and 2 are related to Caulerpa taxifolia 18SrRNA, but in the phylogenetic tree result, Sample 1 was more closely related to Caulerpa sertularioides f. longipes. 18SrRNA primers have been used for molecular identification of green seaweed from Mandangin for the first time and this shows that barcode markers can be used for molecular identification of seaweed, specifically Caulerpa in the waters of Mandangin Island, Indonesia.

Abstract

In the present work, the feasibility of fattening Oreochromis niloticus specimens on a pilot scale in a geothermal water resource located in the Southeast of the province of Buenos Aires was analyzed. Before placing the culture units, physical and chemical characteristics of hot spring were studied to evaluate its suitability for tilapia farming. In the experimental stage, two hundred specimens with an average weight of 14.5 ± 1.8g were placed in two floating cages (1.30x1x1m) (100 individuals per cage) and they were harvested at 140 days. The specimens were fed 3 times a day with a commercial pelleted feed with a content of 35% of proteins. Monthly samplings were carried out to evaluate growth (weight and total length), survival, and water samples were collected to measure their physical-chemical characteristics. The results of the water analysis showed a high quality in the hot springs (Simplified Water Quality Index=88). The fattening results showed an average final weight of 423-435.9 g, a survival of 87-91%, a SGR 1.47- 1.49% / day and  the FCR was estimated at 1.05-1.07 for each cage respectively. We can conclude that this hot spring has the necessary water conditions to obtain excellent weight gains during the fattening period for the O. niloticus specimens. The present study represents the first Nile tilapia culture in the southernmost thermal waters, setting a precedent for future ventures in the area.
