The role of brain peptides in the reproduction of blue gourami males Trichogaster trichopterus. In all vertebrates, reproduction and growth are closely linked and both are controlled by complex hormonal interactions at the brain-pituitary level.

In this study, we focused on the reciprocal interactions between brain peptides that regulate growth and reproductive functions in a teleostei fish blue gourami Trichogaster trichopterus. These findings together with previous studies were used to ijan a model summarizing the mechanism of brain peptides GnRH, PACAP and its related peptide and the relationship to reproduction and growth through pituitary atmbakan gene expression during ontogenesis and reproductive stages in blue gourami.

Replacement of fish meal protein by surimi by-product protein in the diet of blue gourami Trichogaster trichopterus fingerlings. The formulated diets were fed ad libitum to T. While whole-body protein content of fish was marginally decreased, the lipid content was increased with increase in surumi by-product incorporation level in the diet. Temperature affects brain and pituitary gene expression related to reproduction and growth in the male blue gouramisTrichogaster trichopterus.

This study examined the effect of temperature on reproduction and growth-related factors in blue gourami males under nonreproductive and reproductive conditions.

Nests were observed only ikab males under reproductive conditions. In conclusion, we propose that tambaakan has more effect on the transcription of genes, associated with reproduction, than on those pertaining to growth.

Acute toxicity of chlorpyrifos to embryo and larvae of banded gourami Trichogaster fasciata. Tambaka study elucidated the acute toxicity of chlorpyrifos on the early life stages ikkan banded gourami Trichogaster fasciata. To determine the acute effects of chlorpyrifos on their survival and development, we exposedthe embryos and two-day-old larvae to six concentrations 0, 0.

Biological nutrient recovery from culturing of pearl gourami Trichogaster leerii by cherry tomato Solanum lycopersicum in aquaponic system.

The possibility of using different densities of cherry tomato as a bio-filter in a simple media-based aquaponic system to recycle nutrients from pearl gourami intensive culture wastewater was evaluated.

Water quality parameters including total ammonia nitrogen TANnitrite NO 2 -nitrate NO 3 -phosphate PO 4 3-pH, and dissolved oxygen DO were determined in outlet of the aquaponic system during a day experimental period.

Cherry tomato was planted at four densities of 0 control3 T16 T2and 9 T3 plants per aquaponic unit with a constant fish stock density. Each treatment was equipped with aquaponic systems containing fish tank and plant growing bed. Productivity of the system was measured by recording the fish and plant growth indices.

Environmental modulation of the onset of air breathing and survival of Betta splendens and Trichopodus trichopterus. The effect of hypoxia on air-breathing onset and survival was determined in larvae of the air-breathing fishes, the three spot gourami Trichopodus trichopterus and the Siamese fighting fish Betta splendens.

Larvae were exposed continuously or intermittently 12 h nightly to an oxygen partial pressure PO2 of 20, 17 and 14 kPa from 1 to 40 days post-fertilization dpf.

Survival and onset of air breathing were measured daily. The same conditions altered the onset of air breathing, advancing onset by 4 days in B. These interspecific differences were attributed to air-breathing characteristics: Iridovirus disease in two ornamental tropical freshwater fishes: African lampeye and dwarf gourami.


Many species of ornamental freshwater fishes are imported into Japan from all over the world. We found African lampeye Aplocheilichthys normani and dwarf gourami Colisa lalia suffering from an iridovirus infection just after being imported by tropical fish wholesalers from Singapore.

African lampeye were cultured on the Indonesian Island of Sumatra and dwarf gourami were cultured in Malaysia before export. Diseased fishes displayed distinct histopathological signs of iridovirus infection: Electron microscopy revealed viral particles African lampeye: Digenic control of colouration in the two-spot gourami Trichogaster Vietnam, Malaysia, Sumatra, and many of the surround Feeding okan of giant gouramiOsphronemus gouramy Lacepede larvae.

Directory of Open Access Journals Sweden. Full Text Available Gambakan experiments were carried out in liter glass aquaria with 10 liters of water containing larvae aged 1. It was found that the feeding scheme of larval giant gourami aged days TL 8. The larvae aged days TL Larvae aged more than days TL Daily food uptake by the larvae and juvenile were determined in a liter aquaria water volume 10 liters containing larvae.

Aquaria without larvae were also set for a control of natural fluctuation in food density. The amount of food intake was calculated based on changes of food density in the aquarium with and without fish larvae. In vivo test was performed by injecting bacteria 0. In vitro study showed that prevention area of leaf extract against Aeromonas hydrophila was increase by increasing the concentration of leaf extract used, reached 9,33 mm. Prevention tambakah of leaf extract by difusion tends to constant, reached 7,6 mm.

By in vivo test, survival rate of giant gouramy infected by Aeromonas hydrophila was no significantly different between dosages of leaf extract. All treated fish, excluded control died after 24 hours infection.

Reproductive hormone profiles and gametogenesis in female of giant gouramy Osphronemus gouramy.

Full Text Available Giant gouramy is one of freshwater aquaculture fish species that has high economic value so that various efforts had been performed to continuous increase its production ikzn.

The successful of giant gouramy culture requires good understanding on its reproductive biology, however limited information is available. Therefore, this study was conducted to determine reproductive hormone profiles and gametogenesis of giant gouramy for a cycle of reproduction.

Eighteen broodstocks were naturally spawned; the day of spawning was referred as the first day zero weeks of post spawning.

[Freshwater fishes culture]. [Indonesian] [1988]

Nine Group A of those broodstocks were used to evaluate gonadotropin, estradiol, and progesterone profiles. The txmbakan broodstocks group B were used to evaluate gametogenesis. Blood sample from fish group A were taken on 0, 1, 2, ta,bakan and 4 weeks post spawning for measurement of hormone levels. On the same time, ovarian were taken ikab fish group B.

Ovarian were weighted to examine gonado somatic index GSI, and they were then be fixative by NBF solution, processed to histology using paraffin, and stained with haematoxyline-eosin.

Histology of ovarian was observed using a light microscope. The results of hormone analysis showed that the level of gonadotropin was relatively high during the spawning 0. Progesterone level from fish spawning to the first week was 0. Viability test of fish scale collagen Oshpronemus gouramy on yambakan hamster kidney fibroblasts fibroblast cell culture.
