GENETICS of the SIAMESE FIGHTING FISH, BETTA Splendensl
GENETICS OF THE SIAMESE FIGHTING FISH, BETTA SPLENDENSl HENRY M. WALLBRUNN Department of Biology, Uniuersity of Florida, Gainesuille, Florida First received March 13, 1957 ETTA SPLENDENS more commonly known as the Siamese fighting fish has B been popular in aquariums of western Europe and America for over 35 years. Its domestication and consequent inbreeding antedates the introduction into the West by 60 or 70 years. Selection for pugnacity, long fins (see Figure l), and bright colors over this long period has produced a number of phenotypes, none of which is very similar to the short-finned wild form from the sluggish rivers and flooded rice paddies of Thialand (SMITH1945). The aquarium Betta is noted for its brilliant and varied colors. These are pro- duced by three pigments, lutein (yellow), erythropterin (red), and melanin (black) ( GOODRICH,HILL and ARRICK1941 ) and by scattering of light through small hexagonal crystals (GOODRICHand MERCER1934) giving steel blue, blue, or green. Each kind of pigment is contained in a distinct cell type, xanthophores, containing yellow, erythrophores red, and melanophores black. There are no chromatophores containing two pigments such as the xanthoerythrophores of Xiphophorus helleri. The reflecting cells responsible for iridescent blues and greens are known as iridocytes or guanophores and they are more superficial than the other chromatophores. Since the pigment granules may be greatly dispersed in the many branched pseudopods or clumped into a small knot in the center of the chromatophores, the color of any single fish may vary over a wide range of shades, and may do SO in a matter of seconds. -

We suggest that the integration of genomic Sexual selection Speciation approaches with ecological and behavioural studies, across the entire cichlid family and beyond it, will contribute to the utility of the cichlid model system for understanding the evolution of biological diversity. -

Checklist of the Cichlid Fishes of Lake Malawi (Lake Nyasa)
Checklist of the Cichlid Fishes of Lake Malawi (Lake Nyasa/Niassa) by M.K. Oliver, Ph.D. ––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––– Checklist of the Cichlid Fishes of Lake Malawi (Lake Nyasa/Niassa) by Michael K. Oliver, Ph.D. Peabody Museum of Natural History, Yale University Updated 3 November 2018 First posted June 1999 The cichlids of Lake Malawi constitute the largest vertebrate species flock and largest lacustrine fish fauna on earth. This list includes all cichlid species, and the few subspecies, that have been formally described and named. Many–several hundred–additional endemic cichlid species are known but still undescribed, and this fact must be considered in assessing the biodiversity of the lake. Recent estimates of the total size of the lake’s cichlid fauna, counting both described and known but undescribed species, range from 700–843 species (Turner et al., 2001; Snoeks, 2001; Konings, 2007) or even 1000 species (Konings 2016). Additional undescribed species are still frequently being discovered, particularly in previously unexplored isolated locations and in deep water. The entire Lake Malawi cichlid metaflock is composed of two, possibly separate, endemic assemblages, the “Hap” group and the Mbuna group. Neither has been convincingly shown to be monophyletic. Membership in one or the other, or nonendemic status, is indicated in the checklist below for each genus, as is the type species of each endemic genus. The classification and synonymies are primarily based on the Catalog of Fishes with a few deviations. All synonymized genera and species should now be listed under their senior synonym. Nearly all species are endemic to L. Malawi, in some cases extending also into the upper Shiré River including Lake Malombe and even into the middle Shiré. -

Species Composition and Invasion Risks of Alien Ornamental Freshwater
www.nature.com/scientificreports OPEN Species composition and invasion risks of alien ornamental freshwater fshes from pet stores in Klang Valley, Malaysia Abdulwakil Olawale Saba1,2, Ahmad Ismail1, Syaizwan Zahmir Zulkifi1, Muhammad Rasul Abdullah Halim3, Noor Azrizal Abdul Wahid4 & Mohammad Noor Azmai Amal1* The ornamental fsh trade has been considered as one of the most important routes of invasive alien fsh introduction into native freshwater ecosystems. Therefore, the species composition and invasion risks of fsh species from 60 freshwater fsh pet stores in Klang Valley, Malaysia were studied. A checklist of taxa belonging to 18 orders, 53 families, and 251 species of alien fshes was documented. Fish Invasiveness Screening Test (FIST) showed that seven (30.43%), eight (34.78%) and eight (34.78%) species were considered to be high, medium and low invasion risks, respectively. After the calibration of the Fish Invasiveness Screening Kit (FISK) v2 using the Receiver Operating Characteristics, a threshold value of 17 for distinguishing between invasive and non-invasive fshes was identifed. As a result, nine species (39.13%) were of high invasion risk. In this study, we found that non-native fshes dominated (85.66%) the freshwater ornamental trade in Klang Valley, while FISK is a more robust tool in assessing the risk of invasion, and for the most part, its outcome was commensurate with FIST. This study, for the frst time, revealed the number of high-risk ornamental fsh species that give an awareness of possible future invasion if unmonitored in Klang Valley, Malaysia. As a global hobby, fshkeeping is cherished by both young and old people. -
