SynopsisThe life history characteristics of tule perch were compared within and among populations in three drainages with substantially different environmental conditions. Within populations there were, in general, substantial increases in brood size, size of young, brood weight, and gonadal-somatic index (GSI) with age and with size of female. In at least one population there was a trade-off between the number and size of young produced. However, in a lake where individual growth was very slow… 

The life history and fishery potential of Labeo umbratus (Teleostei: Cyprinidae) in five small South African reservoirs

There was a weak relationship between the fishery potential of L. umbratus populations and algal biomass, and thus it was concluded that populations in small, shallow, slightly enriched reservoirs would be those more suitable for exploitation.

Fecundity is highest in the species which occupies highly seasonal freshwater environments, Coastal species produce moderately large broods and species which occupy stable deep water environments produce the smallest broods.

Patterns of reproduction in two populations of pumpkinseed sunfish,Lepomis gibbosus, with differing food resources

Variation in patterns of reproduction between populations suggests that fish may be able to fine-tune responses to local environmental conditions.

Microgeographical variation in ovum size of the blacktail shiner, Cyprinella venusta Girard, in relation to streamflow

– There is a strong, positive correlation between egg size and the discharge variable mean annual runoff among populations of Cyprinella venusta Girard from streams in different drainages ranging


The reproductive biology of intertidal, black brown frillfin goby, Bathygobius fuscus (Ruppell) have been surveyed from the coastal region of Keelung, Taiwan and the higher reproductive season can be well observed from female GSI (Gonadosomatic Index) during May to September.

Habitat influences on reproductive allocation and growth of the mummichog (Fundulus heteroclitus) in a coastal salt marsh

While the length of the spawning season differs in mummichogs inhabiting marsh creeks and ponds, annual reproductive allocation depends more upon the hydrodynamic conditions of the particular waterbody than its habitat type per se.

Diet, size and reproductive biology of the silver catfish, Chrysichthys nigrodigitatus (Siluformes: Bagridae) in the Cross River, Nigeria.

The silver catfish, Chrysichthys nigrodigitatus (Lacépède: 1803) is a highly valued food-fish included among the dominant commercial catches exploited in major rivers of Africa. To provide useful

Life-history variability of non-native centrarchids in regulated river systems of the lower River Guadiana drainage (south-west Iberian Peninsula).

Life-history variability of two non-native centrarchids, pumpkinseed Lepomis gibbosus and largemouth bass Micropterus salmoides, was evaluated in three stream stretches of the lower River Guadiana drainage with different degrees of regulated flows, demonstrating the importance of species adaptation to local conditions which might favour their invasion success.

Comparative life history of female mosquito fish, Gambusia affinis, in tidal freshwater and oligohaline habitats

It is suggested that Gambusia affonis may have a greater reproductive effort in low salinity/near-neutral pH environments than in freshwater/low pH habitats.

Reproductive Morphology of Male Black Perch (Embiotoca jacksoni)

The progression of spermatocyte development and formation of the spermatozeugmata within the testicular tissue is documented and histology is used to detail the association of the intromittent organs with the anal fin.



Latitudinal Variation in Reproductive Characteristics of American Shad (Alosa sapidissima): Evidence for Population Specific Life History Strategies in Fish

The reproductive characteristics of five populations of American shad on the Atlantic coast were studied and the pattern of reproductive responses of shad to the thermal environment of the natal river is consistent with existing ecological theory concerning the evolution of reproductive strategies.

Morphometric Analysis of Tule Perch (Hysterocarpus traski) Populations in Three Isolated Drainages

Morphometric analysis of tule perch from six sites in three isolated drainages supports the view that populations in separate drainages are sufficiently distinct to warrant subspecific designation.

Life history patterns of a livebearing fish in contrasting environments

The population dynamics and energy allocations of the Gila topminnow, a small livebearing fish, were studied in two contrasting environments, a spring run of constant characteristics and a fluctuating desert wash, where many fish in both areas matured the year after their birth.


The present paper is an account of some of the investigations on the biology of the perch in Windermere, which are being conducted in connexion with a trap-fishery experiment, which revealed the relative complexity of the interrelationships of length, weight and condition.

Reproductive Guilds of Fishes: A Proposal and Definition

Thirty-two guilds putatively encompass all living fishes, based mainly on form and function in early developmental intervals, on preferred spawning grounds, and on features of reproductive behavior, based on an earlier concept of ecological groups.

Environmental Influences on Early Development and Year-Class Strength of Northern Pike in Lakes Oahe and Sharpe, South Dakota

Estimates of year-class strength of northern pike in the two reservoirs suggest that large year classes were associated with stable to rising water level and temperature, flooded vegetation, and calm weather during the spawning season, while small year classes have been associated with abrupt water temperature fluctuations, dropping water level, and high silt deposits.

Inherited interpopulation differences in size at first reproduction in threespine stickleback, Gasterosteus aculeatus L.

Field and laboratory data indicate that interpopulation differences in minimum size at first reproduction are inherited and probably represent local adaptations.

Fecundity of Grand Bank Haddock

Fecundity of Grand Bank haddock was investigated and it was found that fecundity increased at a rate proportional to about the fifth power of the body length and to the square of the age, the correlations between feces and length being better than those between age and length.

The White Perch in Nebraska

Sexually mature white perch (Morone americana), brought into Nebraska in the spring of 1964, spawned successfully in hatchery ponds and completely displaced the native black bullhead as the dominant species in the reservoir.
