Botia fish (clown loach) growth is relatively slow, taking 4-5 months to reach marketable size (2 inch) and 3 years to achieve initial gonad maturation in female and 1 year in male fish. Environmental degradation and overfishing are factors triggering the production of newly potential broodstock. This study aimed to observe the growth response of potential broodstock through rearing technique with and without shelter. Fish were kept inside the aquaria sized 80x40x30 cm with 20 cm water height on the recirculation system. Fish used for shelter treatment were: Total length ± 7.7 cm, height ± 2.09 cm, and weight ± 7.33 g; for no shelter treatment were: Total length ± 6.7 cm, height ± 1.88 cm, and weight ± 4.59 g. Fish were stocked 10 fish / aquarium and fed 3 times / day by at satiation method. Parameters observed were total length, height and weight improvement also water quality. The results showed that growth and feed efficiency had better value when reared with shelter than without shelter.

The research is aimed to know the supplementation effect of different concentration of Spirulina platensis fluor on artificial feed against the growth and feed efficiency of goldfish. The experimental research was carried out on September 2018 until April 2019 at The Fisheries Laboratory, Djuanda University, Bogor. The experimental research used completely randomized design with 4 treatments and each 3 replications. The treatments are K (Control, without supplementation of Spirulina platensis fluor), A (30 g of Spirulina platensis fluor + 1 kg  of artificial feed), B (60 g of Spirulina platensis fluor + 1 kg  of artificial feed), and C (90 g of Spirulina platensis fluor + 1 kg  of artificial feed). The total length growth, the weight growth, feed efficiency, and water quality (temperature, pH, dissolved oxygen, and NH3) had been evaluated.  The results of research showed there was  a significantly different between treatments for the growth and feed efficiency (P<0.05).  The best results were obtained in treatment B with an average total length growth of 2.19 cm, average weight growth of 1.51 g, and average feed efficiency of 30.26%. Water quality during the research are temperaure of 25.6-27.5oC, pH of 7.2-8.3,  DO of 6.2-7.1 mg/L, and NH3 of 0.01-0.30 mg/L.Key words : Goldfish, Spirulina platensis, growth, feed efficiency

One of the technologies to keep the water quality remains optimal ias a recirculation system. This research is aimed to determine the influence of denisity of catfish (Clarias gariepinus) on the recirculation system. Fish test used is catfish fry the age of 2 weeks with average weight 0.58 g and an average length of 2.7 cm as much as 10,000 fish. The experimental research used completely randomized design with 4 treatments and 3 replications. The treatments were A (20 fish/liter of water), B (30 fish/liter of water), C (40 fish/liter of water) and D (50 fish/liter of water). The survival rate, the feed efficiency, and water quality has been observed. The results of research showed that the survival rate and the feed efficiency were significantly different (P<0.05). The highest survival rate in this research was in the treatment A (20 fish/liter of water) that was 70.5%. The stocking density of catfish fry of 20 fish/liter of water can be used as basis for  the maintenance of catfish fry for reach the optimal survival rate. Key words: Catfish, survival rate, feed efficiency, recirculation

This research aims to determine the effect of fine bubble technology with different pressures on Siamese catfish seed's growth and feed efficiency in an aquaponic system. This research used a completely randomized design with four treatments and three replications. Treatment A (Control), Treatment B (FBs with a pressure of 4.5 atm), Treatment C (FBs with a pressure of 5 atm and treatment D (FBs with a pressure of 5.5 atm). The parameters observed were Specific Growth Rate, Feed Conversion Ratio, water quality (temperature, pH, DO, and ammonia), and plant productivity.  The seeds used were catfish seeds aged 16-36 days, 1-2 inches long, and weighed 0.26-0.29 grams. The container used is a fiber tub of 16 units with a size of 70 cm x 70cm x 70 cm. The feed used is commercial feed PF 1000 content crude protein 35%. The data were analyzed using variance with the F test at the 95% confidence level. The best treatment for catfish growth was treatment D (pressure 5.5 atm), which gave the highest SGR value of 7.24 ± 0.5 and FCR value of 1.19 ± 0.09. The value of water quality parameters is in suitable condition for the growth of catfish seed. The best plant productivity was found in treatment D with an average weight of 60.75 g.

Fish Trade

Ornamental fish trade between regions in Indonesia allows the transfer of disease, especially if the disease does not show clinical symptoms in fish traded. Koi fish in Tahuna, North Sulawesi, mostly come from the area of ​​East Java, which is one area with many cases of myxobolusis. In addition, the potential for parasitic diseases that come along when koi fish are brought between areas cannot be avoided, because the examination of parasites, especially Myxobolus sp. no longer listed in the regulation as a quarantine inspection requirement. The purpose of this study was to see the Myxobolus sp infestation that infected koi in Tahuna, North Sulawesi, although there were no clinical symptoms using conventional techniques and histopathology. The results of the examination showed Myxobolus spore infestation on the gills of the koi, although the amount was not much, both conventional and histopathological techniques. This shows that our level of awareness of the types of parasites that can infect fish is still lacking. Myxobolus sp is only transmitted through the spore stage back and forth; there is no horizontal or vertical transmission in fish or tubifex T worm populations. More knowledge regarding the life cycle of the Myxobolus sp. in order to obtain the right handling to deal with outbreaks, especially water quality management at the location of the cultivation.

The present study describes Camallanus maculatus n. sp. (Nematoda: Camallanidae) from Xiphophorus maculatus (Osteichthyes: Poecilidae) collected in an ornamental fish farm in São Paulo State, Brazil. Thirty-three out of 40 examined fish were parasitized (82% prevalence) with mean intensity of 2.8 (1-20). Male specimens were 3,500µm total length and females 7,100µm total length, provided with orange-brown buccal capsule and two developed tridents. Males showed two unequal spicules, gubernaculum absent and females with vulva situated in the middle of the body. The main characteristics were the sleekly longitudinal ridges in the buccal capsule in both sexes, enlargement at the anterior end of the smaller spicule, the number of genital papillae, longer muscular and glandular portion of esophagus and round tail in female.
