Abstract

Indonesia is a fishery center that contributes significantly to international fish production. The amount of fish production can not be separated from the cultivation of both consumption fish and ornamental fish. One of the ornamental fish that has been developed and has become the main commodity for trading is koi fish, and it has even become a mainstay commodity in several areas including Sukabumi, Cianjur, and Blitar (Kursini, 2015). Therefore, it is necessary to do research on the effect of different administration of Pseudomonas putida on the survival of Koi fish. The method used in this research is the experimental method, which is then repeated 3 times each. The results of the test of the effect of giving Pseudomonas putida in this study resulted that the higher koi fish weight gain in the aquaponics system was 4.8±0.12%, while the lowest koi fish culture was 3.6±0.12%. while the average pH of koi fish in aquaponic systems is higher, namely 8.36. Meanwhile, in the lowest koi fish culture, the results are 8.25 and Phosphate that the average phosphate of koi fish in aquaponic systems is higher, which is 2, 58 mg/l, while the lowest koi fish culture yielded 1.11 mg/l which decreased and improved water quality.

Abstract

Lately in some areas there have been cases of death in the cultivation of tilapia fish en masse which is likely to be an infection of TiLV disease. TILV that attacks tilapia can be quick diagnosed with RT - Polymerase Chain Reaction (RT-PCR) method. This examination method detect the virus through the presence of its RNA. The purpose of this study is to determine the effectiveness of RT-PCR method in detecting disease in tilapia (Oreochromis niloticus) at the Fish Quarantine Station for Quality Control and Safety of Fishery Products in Medan I (BKIPM Medan I). Qualitative research method was conducted in BKIPM Medan I. Tilapia sample were taken from tilapia pond in Porsea and Laguboti, Toba Samosir, North Sumatera. Fifteen tilapias were taken from each pond. The sample criteria was 30 days old tilapia or tilapia that shown clinical symptom. RT-PCR method was perform at sample brain, kidney, and liver. The result from RT-PCR than analyzed and compared with the literature. The results of the study using the RT-PCR method on samples of tilapia (Oreochromis niloticus) from Porsea sub-district showed positive infected with TILV with the results of electrophoresis rna band TiLV appeared at 250 bp and the percentage of infestation of 66.67%. While fish from Laguboti subdistrict there is no indication of TILV disease with the percentage of tilapia infestation (Oreochromis niloticus) affected by Tilapia Lake Virus (TiLV) disease by 0%. While fish from Laguboti subdistrict there is no indication of TILV disease with the percentage of tilapia infestation (Oreochromis niloticus) affected by Tilapia Lake Virus (TiLV) disease by 0%. So it can be concluded that RT-PCR effectively detects TILV disease in tilapia fish.

Abstract

The rise of tilapia fish cultivation cannot avoid the application of high cultivation intensification. This can have a negative impact, one of which was the onset of Motile Aeromonas Septicaemia (MAS). Motile Aeromonas Septicaemia (MAS) was one of the diseases that can attack tilapia, this disease was caused by the bacterium Aeromonas hydrophyla. The study aimed to determine the effect of the use of pepaya seed extract (Carica papaya L.) on the survival of tilapia fish, tilapia growth and the profile of red blood cells of tilapia fish infected with A. hydrophila bacteria. The research method used was an experimental method with a completely randomized design (CRD) while the treatments are P1 (immersion with a concentration of 20%), P2 (30%), P3 (40%), P4 (50%) carried out for 30 days. The results showed the highest survival in the P3 treatment which is 66.66% and the lowest is P0 which is 13.33%, red blood test results show healthy fish blood on average above 30x10? cells / mm³ while sick fish that have been infected with A. hydrophila bacteria point to an average of above 5x10? cells / mm³ and fish in the treatment of P1, P2, P3, and P4 that have been soaked using pepaya seed extract and maintained for 14 days show blood test results above 25x10? cells / mm³ while fish that are not soaked show the results of calculations of 17.4x10? cells / mm³. The conclusion of this study was that P2 treatment with a dose of 30% was recommended for the survival rate of tilapia fish. P1 with a dose of 20% with the administration of pepaya seed extract has a real effect on the number of red blood cells of tilapia fish. As for the absolute long growth and absolute weight of tilapia fish, the immersion of pepaya seed extract has no real effect.

Abstract

In spawning clown fish it takes a treatment on the manipulation of the place of origin of clown fish to spawn in cultivation containers. Tile and ceramic substrates are suitable for the attachment of clownfish larvae because the texture of the two substrates is hard, this indicates that the type of hard substrate will be able to be made a living place for clownfish, because the properties of clown fish must grow and develop in hard substrates. This research was conducted with the aim of studying differences in the survival of clown fish larvae on different substrates. This research was conducted for 45 days, starting from 1 September to 15 October 2021 at the Lombok Marine Cultivation Fisheries Center (BPBLL). The method used in this research is to use an experimental method with a completely randomized design (CRD) pattern with four treatments with 3 replications, namely P1 (ceramic substrate), P2 (tile substrate), P3 (paralon substrate), P4 (pottery substrate). . The test animals used in this study were male and female clown fish (Amphiprion ocellaris) aged between 4-5 years. Based on the research that has been done, there are fertilization results P1 = 88.67%, P2 = 94.17%, P3 = 83.83%, P4 = 78.67%. While the results of hatchability P1 = 88.67%, P2 = 94.17%, P3 = 83.83%, P4 = 78.67%. And the results of survival were P1 = 82.15%, P2 = 82.84%, P3 = 80.94%, P4 = 80.11%. The conclusion of this study was that the use of ceramic, tile, paralon, and earthenware substrates had no effect on fertilization and hatchability of clown fish eggs. The survival of clown fish has a significant effect on the use of substrate in spawning clown fish.

Abstract

The main problem faced today is the low level of postlarva vannamei even though various acclimatization methods have developed to low salinity. Efforts are needed to be able to deal with the problem of delayed growth of shrimp maintained at low salinity. One of them is by adding calcium in the cultivation media. Calcium solubility is needed in order to help the process of calcium absorption. This study aim to improve the dissolution rate of calcium with the addition of ketapang leaf for increased production performance and the growth of vaname shrimp larva (Litopenaeus vannamei). This study used completely randomized design (CaCO3) with 5 treatment and 3 replacement. Doses that used in this study were 50 ppm of lime with 0, 0,12, 0,24, 0,36, and 0,48 ppt doses of ketapang leafs. Observational parameters werw absolute growth rate of weight, absolute growth rate of length, survival rate, feed conversion ratio, oxygen consumption rate, calciums level in water and water quality contains temperature, pH, DO, salinity, and ammonia. The results showed that the addition of 0,48 doses of ketapang leaf significantly effected absolute growth rate of length growth, feed conversion ratio, oxygen consumption rate, and calcium level. While the addition of 0,36 doses of ketapang leaf significantly effected survival rate. By the addition of ketapang leaf can improve performance and the growth of vaname shrimp larva.

Abstract

Freshwater ornamental fish commodities are in great demand by people in Indonesia, one of which is guppy fish (Poecilia reticulata). Guppies are very popular because they are easy to maintain and have beautiful color variations, especially for male guppy fish. The constraint in guppies cultivation is that the number of male chicks produced is usually lower than the number of females. The use of mensirak leaf extract is thought to be used in the process of masculinizing guppies. This study was conducted to determine the best dose of mensirak leaf extract to increase male sex ratio in guppies. The method used in this study is an experimental method using a single Completely Randomized Design (CRD) with 5 levels of treatment consisting of 3 replications. The immersion doses of female guppy broodstock used were P1 (2 mg/L), P2 (4 mg/L), P3 (6 mg/L), positive control 17?-methyltestosterone (2 mg/L) and negative control (0 mg/L). L). The results showed that the use of mensirak leaf extract immersing pregnant mothers had a significant effect on the percentage of male sex with the best concentration of 2 mg/L (45.93±27.19%). The masculinization of guppies using mensirak leaf extract on the immersion of pregnant guppy broodstock had a significant effect on the percentage of male sex. The best dose for immersing pregnant guppies using mensirak leaf extract was obtained in treatment P1 with a dose of 2mg/L, which resulted in the percentage of male sex being 45.93±27.19%.

Abstract

The pearl oyster Pinctada margaritifera (Linnaeus, 1758) or black lip pearl oyster is a marinebivalves with important economic value. This Indo-Pacific species is found in abundance in the waters of North Sulawesi, but cultivation activities have not been optimized. Growth information is important for aquaculture activities because it is a useful indicator to determine the health of pearl oysters and environmental suitability (Moussa, 2013). The purpose of this study was to determine the growth pattern of P. margaritifera pearl shells in the waters of North Sulawesi. Species P. margaritifera were collected at a depth of 2-20 m in the waters of North Minahasa Bahoi, Arakan waters South Minahasa and Talengen waters Sangihe Islands, North Sulawesi Province. The morphometric parameters observed included shell length (PC), shell height (TC), shell thickness (tC), and total weight (BT). The relationship between length, height, shell thickness and total weight was analyzed by regression equation. Morphometric measurements of P. margaritifera showed average shell length (PC) of 95.26 mm (Arakan waters), 81.15 mm (Talengen waters) and 70.19 mm (Bahoi waters). The growth pattern of P. margaritifera in the waters of Bahoi, Arakan and Talengen, North Sulawesi Province was allometric negative. This means that the increase in length, height and thickness of the shell is faster than the total weight.

Abstract

Tilapia fish is a freshwater fish commodity that has the potential to be developed for fisheries business. Tilapia fish have many advantages such as easy breeding, fast-growing, and can survive at high salinity. To increase durability at high salinity it is necessary to prepare saline tilapia seeds produced from parentage that is tolerant to high salinity or through the salination process since the size of the seed. The purpose of this study was to determine the survival rate, absolute growth, and water quality during the adaptation period of increasing salinity of tilapia juvenile. The experimental design used was a completely randomized design with three replications. The salinity increase treatments used were A (1 ppt salinity), B (2 ppt salinity), C (3 ppt salinity), D (4 ppt salinity), and E (5 ppt salinity). The results showed the survival rate of tilapia seeds each treatment is treatment A (1 ppt) by 100%, treatment B (2 ppt) by 100%, treatment C (3 ppt) by 100%, treatment D (4 ppt) by 99.2%, and treatment E (5 ppt) by 98.6%. The results of each absolute growth of each treatment are treatment A (1 ppt) of 0.002 grams / day, treatment B (2 ppt) of 0.002 grams / day, treatment C (3 ppt) of 0.001 grams / day, treatment D (4 ppt) of 0.0007 grams / day, and treatment E (5 ppt) of 0.001 grams / day. It can be concluded that the adaptation of fish seeds at different salinities (1 ppt, 2 ppt, 3 ppt, 4, ppt, and 5 ppt) still shows a good survival rate, but the absolute growth of tilapia seeds on the adaptation of salinity increases of 4 ppt and 5 ppt has not been optimal.

Abstract

The spawning sites of Anguilla borneensis and Anguilla celebesensis were in the seas off Sulawesi and the Gulf of Tomini, the spawning sites of Anguilla marmorata and Anguilla bicolor pacifica were in the western part of the North Pacific. The purpose of this study was to find out information on the diversity of eel seeds and adult eels in the Dumoga River based on the abundance of eel seeds and gonad maturity of adult eels. The eel species consisted of 1,106 A. marmorata, A. bic. pacifica as many as 854 tails and Anguilla spp as many as 291 individuals. The caught eel fish were separated based on the morphology of the eel species. Segregation of catches based on special characteristics of eel, namely preanal and predorsal lengths. Anodorsal values were divided into three groups, namely ±15.57% (A. marmorata); ±1.18% (A. bicolor pacifica) and ±7.09% (Anguilla spp.). Meristic values of A. marmorata for spine (TB) total 104-106 units, pre-dorsal TB 17-19, pre-anal TB 36-39 and ano-dorsal TB 18-20. Meristic values of A. bicolor pacifica for spine (TB) totaled 108-112, pre-dorsal TB 32-36, pre-anal TB 32-39 and ano-dorsal TB 0-3. Meristic values of Anguilla spp for spinal (TB) totaled 100-106, pre-dorsal TB 27-29, pre-anal TB 30-33 and ano-dorsal TB 6-12. The growth pattern of adult eels is negative allometric, i.e. the body length gains faster than the slower body weight gain. The condition of adult eels in the Dumoga River is not fat because the condition factor ranges from 0.0024-0.0036. The average length of adult eels was 58.92cm in Anguilla marmorata (GIC 1.57–2.90%); 54.2cm in A. bicolor pacifica (ICI 1.27–2.79%) and 52.32cm in Anguilla spp (ICI 0.97-2.50%).
