Cryopreservation of spermatozoa of the barramundi, Lates calcarifer (Teleostei: Centropomidae)
Aquaculture, 1987Three cryoprotectants, dimethylsulphoxide (DMSO), glycerol and methanol, were tested for their ability to cryopreserve viable sperm from Lates calcarifer. The dilution ratio of milt to diluent was 1:4 (v:v) and the initial freezing rate was 31°C/min. DMSO at a concentration of 5% with either 15% milk powder or 20% egg yolk gave the best results (post ...

Study of age and growth in lates niloticus (centropomidae) at Khartoum
Hydrobiologia, 19671. The vertebrae are the most reliable part of the skeleton for the determination of the age ofLates niloticus. 2. A correlation between the age and size of the fish is recorded. 3. On the average, females are longer and heavier than males of equal ages. 4.

First occurrence of common snook, Centropomus undecimalis (Centropomidae), in Argentinean waters
2006A specimen of common snook, Centropomus undecimalis (Bloch, 1792) (785 mm TL), was caught in the coastal region of Miramar (Buenos Aires Province, Argentina) in 1996. This represents the southernmost record along the south-western Atlantic coast and the first in Argentine waters.

Centropomidae as defined by Greenwood (1976) is composed of three genera: Centropomus, Lates, and Psammoperca. But composition and monophyly of this family have been challenged in subsequent morphological studies. In some classifications, Ambassis, Siniperca and Glaucosoma were added to the Centropomidae.

Journal of Morphology, 2000
The ovarian germinal epithelium in the common snook, Centropomus undecimalis, is described. It consists of epithelial and prefollicle cells that surround germ cells, either oogonia or oocytes, respectively. The germinal epithelium borders a body cavity, the ovarian lumen, and is supported by a basement membrane that also separates the epithelial ...

MASS MORTALITIES OFLATES(PISCES: CENTROPOMIDAE) IN LAKE ALBERT
Journal of the Limnological Society of Southern Africa, 1976SUMMARY Parker attributed a mass mortality of Lates in Lake Albert to the shock effect of an earthquake which occurred at the same time. A consideration of the limnology of the lake and of limitations to the ability of fish to adjust their buoyancy suggests that the immediate cause of the mortality could have been loss of hydrostatic equilibrium when ...

Winter Scale Rings in Lates niloticus (Pisces: Centropomidae) from Lake Chad
Nature, 1965THE formation of scale rings in tropical fishes has usually been ascribed to some form of physiological stress producing a temporary check in the growth-rate. Holden1 thus proved that in Tilapia spp. from Lake Victoria ring formation is associated with spawning; Johnels2 and Daget3 both correlated the annual rings which occur in many West African ...

Environmental Biology of Fishes, 2002
Aggressive mimicry has been proposed for several unrelated fish species both in freshwater and marine environments. I describe herein a few additional examples, including the first ones from brackish water. In one well documented case, juvenile snooks, Centropomus mexicanus (Centropomidae) join bottom-foraging groups of the superficially similar ...

Centropomus is the sole genus of the Centropomidae family (Teleostei), comprising 12 species widely distributed throughout the Western Atlantic and Eastern Pacific, with 6 of them occurring in the Western Atlantic in extensive sympatry. Their life history and phylogenetic relationships are well characterized; however, aspects of chromosomal evolution ...
