Nile tilapia Oreochromis niloticus is a popular freshwater fish that has been extensively and intensively cultured worldwide. However, cryopreservation of its sperm, especially pre-freezing procedure, has not been properly developed. Therefore, the study aimed to determine the best pre-freezing procedure for cryopreservation of Nile tilapia Oreochr...

This study aims to determine the effect of adding red dragon fruit peel extract in feed on the level of color brightness, growth, and survival of guppy fish. This study used a completely randomized design (CRD) method consisting of four treatments and four replications. The administration of dragon fruit peel extract was carried out by spraying it...

The study aims to determine the type of extender and the best dilution ratio for short preservation walking catfish Clarias batrachus sperm at a refrigeration temperature of 4°C. The study employed a completely randomized design with two factors, each consisting of 6 treatments and 3 replications. The experiments were divided into 2 stages: the fir...

There is no known artificial breeding method for depik fish Rasbora tawarensis . Sperm extender and the dilution ratio are crucial factors in the artificial breeding of fish. The current study aimed to assess the effect of several common fish sperm extenders and its dilution ratio on sperm characteristics and fertilization of depik fish eggs. Two s...

Clarias batrachus is native species from the Clarias genus that has significant economic value in the world, including Indonesia. The genetic relationship between C. batrachus populations in Asia has not been intensively studied. This study used the mitochondrial COI gene as a marker to examine the phylogeography pattern of Clarias batrachus in Ind...

Aceh province is renowned for its potential marine resources, including fish, with snapper being one of the most economically important coral fish. In Indonesia, this fish serves as the main target for coral fishing, particularly in Aceh, causing a decline in its wild population. This decline requires a sustainable development management plan by ac...

In current study, effects of L-tryptophan (1.0 mM), Ascorbic acid (1.0 mM) and with the combination of L-tryptophan /ascorbic acid (1.0 mM/1.0 mM) on rainbow trout Oncorhynchus mykiss sperm were investigated during short-term storage. Sperm samples were stored at 4°C in extender consisted of 0.3 M glucose, 10% egg yolk and 10% Dimethyl sulfoxide (D...

In recent years, the development and implementation of fish sperm cryopreservation techniques have become a priority. To date, cryopreservation of fish sperm has been reported in over 200 fish species. Sperm cryopreservation is the process of freezing and storing sperm cells at very low temperatures to maintain their viability and fertility for a s...

Sperm cryopreservation is a sperm storage method that needs to be developed to ensure the availability of climbing perch fish (Anabas testudineus) sperm considering the difficulty of providing quality broodstock. This study aims to determine the effect of several types and concentrations of cryoprotectants on the DNA integrity of climbing perch fis...

Lutjanus or snappers usually known as economical fish in Indonesia and worldwide. This research aims to observe the different phylogeography correlation of Lutjanus bengalensis in Indonesia Waters and South China Sea used COI gene marker. The primary data collected from fish port Pulo Aceh, Indonesia (5 sequences), while the population of others re...

Anabas testudineus, the climbing perch, is a valuable and well-liked freshwater fish with significant commercial worth. This fish is found in Indonesia and other parts of Asia. Nonetheless, there hasn't been much research done on the genetic relationships across Asian populations of climbing perch. Thus, the aim of this work was to use the mitochon...

Lutjanus kasmira is one of the snappers occupying and commonly found in the Arabian Sea and the Bengal Strait. The purpose of this study was to examine the comparative phylogeography pattern of Lutjanus kasmira in the Bengal Strait and the Arabian Sea using the mitochondrial COI gene as a marker. The population sampled of Indonesia was taken from f...

Walking catfish Clarias batrachus is a freshwaterr fish that has high economic value. Currently, the culture of this local catfish has been initiated in Indonesia, but the breeding technology has not been well developed. Therefore, this study aims to explore the type of natural extender for sperm preservation of local catfish C. batrachus so that i...

BACKGRUND: Goldfish Carassius auratus is a popular ornamental fish extensively cultured worldwide. Sperm cryopreservation is a common fish breeding method that ensures sperm availability around the year. Studies on cryopreservation of goldfish sperm, especially on the suitability of cryoprotectant types and pre-freezing time, are scarcely available...

Background: The cryopreservation of the sperm of the depik fish, Rasbora tawarensis, has previously been developed. However, the quality of the sperm post cryopreservation was not satisfactory and might be improved through the application of antioxidants. Objective: To determine the most suitable antioxidant for the cryopreservation of the depik...

The purpose of this study was to identify ectoparasites and their prevalence infecting Rastrelliger kanagurta in North Sumatera, Medan. So far, people use this fish as a processed product. The method used in this study is a survey method with direct collection at the research site. Samples were taken using random sampling technique. Sampling was ca...

Refrigerated preservation is a simple and inexpensive method for the short‐term preservation of fish sperm used in the hatchery. The type of extender is an important factor that determines the nature of the preservation conditions because certain extenders are better suited for preserving sperm obtained from specific species. Therefore, this study...

Mahseers (Cyprinidae) is one of the most important freshwater fish in Southeast Asia. This fish is being a consumption fish, ornamental and sport fishing. Mahseers can grow up to more than 30 kg. Therefore, this species is called The King of The River. This paper reviewed some aspects of this interesting fish. A total of 54 papers have been reviewe...
