The effects of suspensoids on fish
- M. Bruton
- Environmental ScienceHydrobiologia
- 1 June 1985
High suspensoid loads are a common feature of many Southern Hemisphere inland waters. Case studies on a natural lake (Chilwa), a man-made lake (Le Roux) and S.W. Indian Ocean estuaries reveal that…
Have fishes had their chips? The dilemma of threatened fishes

SynopsisThe conservation status and factors threatening fishes worldwide are reviewed in order to introduce a series of one-page articles on ‘Threatened fishes of the world’, and to encourage the…
The food and feeding behaviour of Clarias gariepinus (Pisces: Clariidae) in Lake Sibaya, South Africa, with emphasis on its role as a predator of cichlids
- M. Bruton
- Environmental Science
- 8 July 2010
Catfish predation is discussed in terms of recent predation theory, and their role as predators of cichlids is tentatively postulated as three-fold: to enhance species fitness by removing enfeebled individuals, to dampen fluctuations in prey abundance, and to act as a “regulator”.
The breeding biology and early development of Clarias gariepinus (Pisces: Clariidae) in Lake Sibaya, South Africa, with a review of breeding in species of the subgenus Clarias (Clarias)
- M. Bruton
- Environmental Science, Biology
- 8 July 2010
The breeding biology and early development of the common southern African clariid catfish, Clarias gariepinus (Burchell), are described and the marked dichotomy between nest-guarded in two Asian species, and non-guarding, open-substrate spawning in all other Asian and African species is noted.
A fiftieth anniversary reflection on the living coelacanth, Latimeria chalumnae: some new interpretations of its natural history and conservation status
For this year's 50th anniversary of the famous discovery of the first living coelacanth, retraced the routes and visited the main actors of this zoological drama, facilitated by novel interpretation of earlier data and expeditions to the Comoro Islands.
Aspects of the biology of Tilapia mossambica Peters (Pisces: Cichlidae) in a natural freshwater lake (Lake Sibaya, South Africa)
- M. Bruton, R. E. Boltt
- Environmental Science
- 1 July 1975
The biology of T. mossambica in Lake Sibaya is compared to data on the same, and similar species, in other systems and the importance of the retention of generalized characters for the successful habitation of the cyclically–renewed habitat of the littoral is made.
An inventory of all known specimens of the coelacanth Latimeria chalumnae , with comments on trends in the catches
- M. Bruton, Sheila E. Coutouvidis
- Environmental Science
- 1 September 1991
A list is presented of all known specimens of the coelacanth Latimeria chalumnae based on a survey of the literature and of museum, aquarium and university holdings. Details are given of the date,…
Alternative life-history strategies of catfishes
- M. Bruton
- Biology, Environmental Science
- 1 November 1996
Only two families have successfully colonised the sea; physiological constraints and strong competition from Elasmobranchii and Actinopterygii fishes are probable reasons, and it is notable that the two families that have succeeded have precocial lire histories that are more suited to highly competitive environments.
Alternative Life-History Styles of Animals
- M. Bruton
- BiologyPerspectives in vertebrate science
- 1989
This book discusses the evolution of alternative life styles in fishes, the constraint of maternal nutrition on the trajectory of fetal growth in humans, and the epigenetic mechanisms of bifurcation.
The growth of Tilapia mossambica Peters (Pisces: Cichlidae) in Lake Sibaya, South Africa
- M. Bruton, B. Allanson
- Environmental Science
- 1 November 1974
Pre- and postbreeding feeding migrations, and increases in condition factor, were associated with scale ring formation in Tilapia mossambica Peters* from Lake Sibaya.
