Flexibility of reproductive tactics and their consequences in the brood parasitic fish Pungtungia herzi (Teleostei: Cyprinidae).
The hatching rates of parasitic egg masses were significantly higher than those of non-parasitic egg masses, and the hatching rate of P. herzi eggs exhibited a strong positive correlation with continuous egg guarding by a reproductive O. obscura male, indicating that brood parasitism effectively improves reproductive success in P.Herzi.
Countertactics of the japanese aucha perchsiniperca kawamebari against brood parasitism by the japanese minnowpungtungia herzi
Japanese aucha perch males taking care of eggs and fry are often brood-parasitized by a Japanese minnow, and countertactics of the perch against such brood parasitism were examined in a river of western Japan.
Alloparental care in fishes
Broad patterns of known examples of alloparental care are described, the pathways to adoption are highlighted, and the ways in whichalloparents derive fitness benefits are highlighted.
Exploitation of the eggs of nest associates by the host fish Pseudobagrus nudiceps
Considering the unusual timing and low survival rate of Pu.
Diversity in interspecific interactions between a nest-associating species, Pungtungia herzi, and multiple host species
Compared with another known host, the freshwater perch Coreoperca kawamebari, the observed differences in the impact of nest association to the associate species likely correspond to Differences in the spatial reproductive resources used by the respective hosts.
An intelligent approach to identify parasitic eggs from a slender-billed’s nest
A new method to quantify a parasitic egg from a dataset of egg’s image using Convolutional Neural Network, a supervised learning method used to classify images, to extract features from image to characterize any egg is presented.
Alloparental care in the sea: Brood parasitism and adoption within and between two species of coral reef Altrichthys damselfish?
The first documentation for alloparental care in coral reef fish is provided and why these patterns may reflect conspecific and interspecific brood parasitism is discussed, as well as possible costs and benefits of parasitism to hosts and parasites.
Can a nest associate fish use an introduced host?—Brood parasitism by Pungtungia herzi toward introduced Coreoperca kawamebari
The minnow Pungtungia herzi is a nest associate spawner that utilizes the spawning nests of other species, including freshwater perch, goby, and catfish, but the frequency of utilization was lower than that in the native range of C. kawamebari, suggesting that the minnow has not yet fully used the new host.
Positive Interactions in Freshwater Systems
Positive interspecific interactions (mutualism, commensalism, and facilitation) are ubiquitous in nature, but understudied in freshwater ecosystems. This review assesses the state-of-the-knowledge of


Spawning Association of the Redfin Shiner, Notropis umbratilis, and the Green Sunfish, Lepomis cyanellus'
An odor hypothesis is presented to explain the mechanism involved in the use of sunfish nests by Notropis umbratilis and it is suggested that the scent of milt and ovarian fluid by spawning sunfish initially attracted the shiners to the sunfish nest and sexually stimulated them.
The Ecology of Brood Parasitism in Birds
Counterparts of the cuckoos are known among insects, of which several groups are specialized for interactions with social insects, ranging from facultative commensalism to an inquilinism close to the cucksoo nexus.

In Lake Tanganyika, an endemic mochokid catfish, Synodontis multipunctatus Boulenger, is a brood parasite of mouthbrooding fishes of the family Cichlidae, and the early stages of development of this catfish not only depend upon their hosts for food and protection, but exploit almost their entire parental investment.
