Are Siamese fighting fish rare?

What are the characteristics of a fighting fish?

Another striking feature of domesticated fighting fish is the overgrowth of almost all types of fins.

Why is the Siamese fighting fish so aggressive?

Centuries of artificial selective breeding for beauty and aggression resulted in a plethora of colors, long-fin varieties, and hyper-aggressive behavior in the air-breathing Siamese fighting fish (Betta splendens), supplying an excellent system for studying the genomic basis of phenotypic variations.

Is the fighting fish genome a good reference species for zebrafish?

In brief, the fighting fish genome was used as reference for pairwise whole-genome alignment with zebrafish (D. rerio), medaka (O. latipes), stickleback (G. aculeatus), fugu (T. rubripes), and Nile tilapia (O. niloticus) (downloaded from Ensembl database, release 86) using LASTZ (Harris 2007).

Is the Siamese fighting fish endangered?

Although the Siamese fighting fish is the popular Betta species as a home aquarium pet, there are several other species that have a conservation status of Threatened. Several Betta species have a Vulnerable conservation status according to the IUCN Red List. The species with the scientific name B. livida is Endangered, and B. miniopinna, B.

How many unigenes does a betta fish have?

We obtained a de novo transcriptome of betta fish consisting of 71,775 unigenes with an average length of 1,107 bp and an N50 of 2,225 bp.

Can RNA-Seq provide information on novel genes in Betta fish?

Our results also suggested that the transcriptomic data of the betta fish were effectively assembled and annotated. Moreover, our results suggested that RNA-Seq might provide information on novel genes in betta fish and also indicate that the throughput and sequencing quality was good enough for further downstream characterization.

What is the role of calcineurin in the pathophysiology of zebrafish regeneration?

Kujawski S, Lin W, Kitte F, Börmel M, Fuchs S, Arulmozhivarman G, Vogt S, Theil D, Zhang Y, Antos CL.. 2014. Calcineurin regulates coordinated outgrowth of zebrafish regenerating fins.

What is a Siamese tigerfish?

The Siamese tigerfish, Finescale tiger fish, Scientific Name: Datnioides pulcher, is a critically endangered Asian fish native to the Chao Phraya, Mae Klong and Mekong basins. It can reach up to 18 inches (45 cm) in length, though in the aquarium they generally only get 9 to 12 inches (20-30 cm).

Is the Siamese fighting fish a vulnerable fish?

The Siamese fighting fish is the national aquatic animal of Thailand, which continues to be the leading breeder and exporter of betta fish for the global aquarium market. Despite their popularity as pets, the IUCN has classified B. splendens as “vulnerable” due to increased pollution and habitat destruction. What is a Betta Fish?

How many genes can be detected in an RNA panel?

In another study, Dacic et al. evaluated an RNA panel allowing the analysis of 169 gene fusions in 19 genes, including the imbalance detection of 12 kinases, using an Ion Proton system.

What are the advantages of using RNA as a sequencing tool?

RNA-based approaches have the overall advantage of allowing an analysis of transcriptionally expressed gene fusions and sequencing is not affected by intronic regions [13]. In addition, RNA panels, besides gene fusions, allow a contemporary analysis of exon skipping events and expression levels of genes with a clinical value [42].

Can a male Betta fish breed with a female?

When you’re trying to breed your bettas, you can allow one male to enter the sorority for a short interval. You cannot leave him in the tank, as male and female bettas do not get along for long. You can’t keep the bettas near the eggs, as they have a tendency to eat them.

How does the potassium-leak channel maintain allometric growth in zebrafish appendages?

The increase in activity of the two-pore potassium-leak channel Kcnk5b maintains allometric juvenile growth of adult zebrafish appendages. However, it remains unknown how this channel maintains allometric growth and how its bioelectric activity is regulated to scale these anatomical structures.

How do calcineurin and kcnk5b affect the size of fins?

In turn, this affects the movement of potassium ions across the membrane, changing electrical activity and, as a consequence, the proportional growth of the fin. Further work should explore how Kcnk5b and calcineurin link to other signals that regulate the size of fins and limbs.

How do calcineurin and kcnk5b control appendage growth in zebrafish?

Kcnk5b and calcineurin seem to play similar roles in the proportional growth of the fins in relation to the body, but exactly how was unknown. To investigate this question, Yi et al. used genetically modified zebrafish to show how the Kcnk5b channel could control genes responsible for appendage growth.

How does calcineurin affect potassium activity?

Yi et al. also showed that calcineurin can modify the Kcnk5b channel to control its activity. In turn, this affects the movement of potassium ions across the membrane, changing electrical activity and, as a consequence, the proportional growth of the fin.

How many eyes does a betta fish have?

Betta fish have two eyes, located on each side of their head. Upon close inspection, you will notice they protrude in a bubble with the top portion making up the interorbital region and the bottom of the eye-socket being the suborbital region. A disease that affects the eye and shows visible symptoms is known as popeye.

How has RNA deep sequencing changed the immune-related genes in fish?

Recently developed RNA deep sequencing technologies, such as Solexa/Illumina RNA-seq and Digital gene expression (DGE), have dramatically changed the way immune-related genes in fish are identified because these technologies facilitate the investigation of the functional complexity of transcriptomes [ 11, 12 ].

What is retinoic acid signaling in zebrafish fin regeneration?

Retinoic acid signaling controls the formation, proliferation and survival of the blastema during adult zebrafish fin regeneration. Development (Cambridge, England), 139(1), 107–116. doi:10.1242/dev.065391[PubMed] [Google Scholar]

What is the function of notch in zebrafish fin regeneration?

Notch regulates blastema proliferation and prevents differentiation during adult zebrafish fin regeneration. Development (Cambridge, England), 140(7), 1402–1411. doi:10.1242/dev.087346[PubMed] [Google Scholar] Nabrit, S.M. (1929). The role of the fin rays in the regeneration in the tail fins of fishes (in Fundulus and Goldfish). Biol.

Why study the caudal fin of the zebrafish?

As in goldfish, the zebrafish caudal fin has several ideal properties for experimental procedures and regeneration studies. First, it is the largest external appendage located at the posterior end of the body, which makes it the most accessible for surgery and imaging.

What kind of fish is a Siamese tiger fish?

The Siamese Tiger Fish is one of two commonly available Datnoids, or “dat’ species. The other is the Silver Tigerfish or Four-barred Tigerfish Datnioides quadrifasciatus.
