Growth and histomorphological responses of Chindongo socolofi to the long‐term replacement of fish meal with defatted Tenebrio molitor meal

Journal of the World Aquaculture Society, Volume 57, Issue 4, August 2026.
Abstract The long‐term suitability of defatted Tenebrio molitor larvae meal (TM) as a substitute for fish meal (FM) protein was evaluated in Chindongo socolofi over a 170‐day feeding period. Six isonitrogenous (38% crude protein) and isoenergetic (4396 kcal kg−1) diets were formulated, in which TM protein replaced FM protein at 0% (control), 20%, 40 ...

Food habits of three non-native cichlid fishes in the lowermost Chao Phraya River basin, Thailand

Journal of Freshwater Ecology, 2019
The food habits of three non-native cichlid fishes, Mayan cichlid (Mayaheros urophthalmus), Mozambique tilapia (Oreochromis mossambicus) and Nile tilapia (O. niloticus), in the lowermost Chao Phraya River basin, Thailand, was examined by stomach contents

Flexible parental care in a songbird correlates with sex‐specific responses to seasonal phenology, mating opportunity and reproductive success

Journal of Animal Ecology, Volume 95, Issue 7, Page 1178-1193, July 2026.
This population‐comparative study reveals that male and female parents respond differently to social and ecological conditions. This sex‐specific responsive strategy is related to the incongruent parental care systems across populations in Chinese penduline tits.

Understanding explosive diversification through cichlid fish genomics [PDF]

, 2018
Owing to their taxonomic, phenotypic, ecological and behavioural diversity and propensity for explosive diversification, the assemblages of cichlid fish in the East African Great Lakes Victoria, Malawi and Tanganyika are important role models in ...

Social organization and habitat use shape the gut microbiome of a marine fish

Journal of Animal Ecology, Volume 95, Issue 7, Page 1091-1107, July 2026.
This study provides the first evidence linking habitat use—and to a lesser extent social organization—to gut microbiome composition in a wild marine fish. The results indicate that local habitat conditions are the primary driver of microbial variation, while social effects are detectable but weak.

Do Coexisting Cryptic Species of Predatory Peacock Bass (Cichliformes: Cichlidae) Partition Their Niche?

Ecology of Freshwater Fish, Volume 35, Issue 3, July 2026.
ABSTRACT The mechanisms facilitating coexistence of cryptic species in sympatry have long puzzled ecologists. Cryptic species have nearly identical morphology and, therefore, would be presumed to have high niche overlap and potential for interspecific competition and competitive exclusion when resources are limited. Lowland rivers in South America have

The role of microRNAs in the repeated parallel diversification of lineages of Midas cichlid fish from Nicaragua [PDF]

, 2016
Cichlid fishes are an ideal model system for studying biological diversification because they provide textbook examples of rapid speciation. To date, there has been little focus on the role of gene regulation during cichlid speciation. However, in recent

Ecophenotypic Variation of Midas Cichlid, Amphilophus citrinellus (Gunther, 1864), in Lake Batur, Bali, Indonesia [PDF]

Brazilian Journal of Biology
Cichlid fishes exhibit rapid adaptive radiations with significant diversification rates in response to ecological variability, i.e., ecological opportunity or geographical isolation.

Signatures of convergence in Neotropical cichlid fish [PDF]

Convergent evolution of similar phenotypes suggests some predictability in the evolutionary trajectories of organisms, due to strong and repeated selective pressures, and/or developmental constraints.

The Accumulation of Reproductive Incompatibilities in African Cichlid Fish [PDF]

, 2009
The rate at which different components of reproductive isolation accumulate with divergence time between species has only been studied in a limited, but growing, number of species.
