The relationship between food availability, cannibalism, and reproduction was investigated experimentally in the live-bearing fish Gambusia affinis. A two-way factorial design was used, with juvenile conspecifics (present or absent) and food (high, variable, or low) as the treatment variables. The results show a significant effect of food level on the occurrence of cannibalism. Cannibalism in turn has an interesting influence on reproductive output. Reproductive output is significantly… 
Cannibalism, Food Availability, and Reproduction in Mosquitofish: A Critique
  • G. Meffe
  • Biology
    The American Naturalist
  • 1986
TLDR
Data from a laboratory experiment testing the relationship between cannibalism, food availability, and reproduction in the mosquitofish, Gambusia affinis support the contention that no maternal energetic input into embryonic development occurs beyond vitellogenesis.
Cannibalism in teleost fish
TLDR
It is considered that cannibalism deserves more attention from fish biologists, and investigations should recognize the different types of cannibalistic interaction, and, in particular, should explore the different implications of kin and nonkin cannibalism.
Cannibalism in the pea aphid, Acyrthosiphon pisum
TLDR
It is found that the starvation treatments had the most significant effect on the prevalence of cannibalism in mature A. pisum, and there was no difference between the prevalence or duration of cannibalistic activities within and between different clones.
Seasonal pattern of filial cannibalism by Apogon doederleini mouthbrooding males
TLDR
No seasonal variation of cannibalism by 2 year-old fish can be explained by their intermediate nature of growth and reproduction, whereas fish 1 year old frequently cannibalized early broods of the season, especially the first brood, whereas the cannibalism rate by 2 years old fish did not vary within the season.
Seasonal pattern of filial cannibalism by Apogon doederleini mouthbrooding males

In temperate waters of southern Japan, mouthbrooding males of the cardinal fish Apogon doederleini sometimes ate their entire brood within a day of spawning. In spite of annual variation in age
Individual differences in egg cannibalism in female dark chub (Pisces: Cyprinidae)
Nine of 41 identifiable females of dark chub, Zacco temmincki, in a river cannibalized eggs of other females. There was no significant difference in body size, condition factor or the location of
Using attraction to light to decrease cannibalism and increase fry production in guppy (Poecilia reticulata Peters) hatcheries. II: the effects of light and cannibalistic adults
TLDR
The results demonstrated the potential efficacy of using white light in reducing cannibalism and increasing fry yields in guppy hatcheries.
The diet of the mosquitofish Gambusia affinis (Baird and Girard) (Poecilliidae) in Mediterranean France
Gambusia affinis (Baird & Girard) , the Mosquitofish, originally native to the coastal region of the southeastern United-States , has been widely introduced throughout the warm temperate and tropical
Consumption of Invasive Western Mosquitofish Fry by Adult Conspecifics and Native Crayfish
TLDR
Results show that cannibalism is a potentially significant source of mortality in Western Mosquitofish, and thus may be a factor involved in the regulation of their population dynamics, and native Little Brown Mudbug, while they do consume mosquitoofish fry, are probably not a major source of mosquitofish mortality in nature.

Effect of Food and Density on Development of Typical and Cannibalistic Salamander Larvae in Ambystoma tigrinum nebulosum
TLDR
The results suggest the typical and cannibalistic larvae which occur in some populations of Ambystoma tigrinum nebulosum is an environmentally induced developmental polymorphism that results from some individuals responding to the environment differently than others.
Cannibalism in Natural Populations
TLDR
It is shown that cannibalism is a normal phenomenon in many natural populations, to evaluate its possible roles in influencing demo­ graphic structure and population processes, and to suggest conditions for, and constraints on, its occurrence.
Effects of Food Supply on Fecundity in the Female Guppy, Lebistes reticulatus (Peters)
TLDR
Three distinguishable size groups of oocytes are contained in the ovary of the viviparous poeciliid, Lebistes reticulates — small, middle-sized, and large — and the effect of changes in the amount of available food on these oocytes and hence on the number of offspring was explored by an experiment involving 27 female Lebists.
Genetics of cannibalism in a viviparous fish and its relationship to population density
TLDR
The genetics of cannibalism and the significance of its density-dependent mechanism in teleosts of the genus Poeciliopsis, a five-membered unisexual–bisexual complex, is examined.
THE IMPACT OF PREDATION ON LIFE HISTORY EVOLUTION IN TRINIDADIAN GUPPIES (POECILIA RETICULATA)
TLDR
Empirical studies have sought correlations between life histories and potential sources of demographic selection and, in some cases, have attempted to determine if the organisms have evolved as predicted by theory, but few have achieved either goal.
REPRODUCTIVE ADAPTATIONS AMONG VIVIPAROUS FISHES (CYPRINODONTIFORMES: POECILIIDAE)
TLDR
Although poeciliids seemingly have sacrificed quantity for quality, they have not done so to the same degree nor by the same mechanism; thus a fairly wide range of productivity levels persists within the family.
Some Developmental Consequences of Handling, Egg‐eating, and Population Density for Flour Beetle Larvae
TLDR
Evidence is presented that egg—eating would also accelerate the development of unhandled larvae and, at the highest egg—feeding rates, the effects of handling and density were almost completely compensated.
DISTRIBUTION, COEXISTENCE, AND COMPETITION OF WHIRLIGIG BEETLES

TLDR
Attempts to generalize about the diversity and relative abundance of species in a community or in a single trophic level might logically proceed from reasoning about how resources are apportioned through competition, and Birch (1957) has composed a verbal definition of interspecific competition.
Nutrition of Gambusia affinis on the rice fields of Turkestan.
TLDR
The analysis showed that Gambusia mostly feeds on products of animal origin, and only in 30 of the 219 adult stomachs analysed were remnants of vegetable food found-13-7 % of the total, in young fish the percentage was 12-9 vegetable.
Cannibalism and Kin Selection in Labidomera clivicollis (Coleoptera: Chrysomelidae)
TLDR
The phylogenetic migrations of the ambient muscle and the evolution of viviparity in marsupials are studied.
