Investigating Common Carp (Cyprinus carpio) as a Novel Feed Ingredient for Diets of Farmed Carnivorous Fish

, 2017
Over 60% of natural fish stocks are either fully‐exploited or overexploited. This declining productivity has led to the rapid growth of the aquaculture industry, or the farming of fish.

She Doesn't Whisper: Female‐Prominent Stridulation Shaped by Morphology in a Buthid Scorpion and Insights on Its Function

Ethology, EarlyView.
Sexual dimorphism and stress‐induced stridulatory responses in Jaguajir rochae (Borelli, 1910). Females exhibited greater absolute pectinal size and higher sound pressure levels, whereas males showed higher pectinal allometric ratios relative to body size, lower sound frequencies, and shorter delta times.

Shelters or ecological traps? Context‐dependent effects of nestboxes on breeding success in a colonial raptor

Ibis, EarlyView.
Artificial breeding structures, such as nestboxes, can potentially influence the population size and conservation status of bird species relying on heavily human‐modified environments such as agroecosystems and urban areas. However, the effectiveness of these interventions may vary, as artificial structures could attract individuals to suboptimal ...

Relationship between Total Length and Digestive Tract of Different Carnivorous Fishes

Progressive Agriculture, 2013
The study was conducted to find out the relationship between total length and alimentary canal of different carnivorous fishes. The morphometry associated with the feeding and digestion of one hundred eighty fishes of 9 species was studied. It was observed that well-defined sharp teeth were present on both jawsof the fishes examined.

Feeding ecology of an Amazonian electric knifefish under altered flood‐pulse dynamics caused by hydroelectric damming

Journal of Fish Biology, EarlyView.
Abstract This study evaluated the effects of the controlled flood pulse on diet composition, trophic niche breadth and feeding intensity of Archolaemus janeae, an electric knifefish species with a restricted distribution in the Amazon Basin. Monthly samples were collected from December 2020 to November 2021 in the Volta Grande stretch of the Xingu ...

Spatiotemporal dynamics of microcystin contamination in fish across the Lake Chaohu basin under the Yangtze River ten-year fishing ban: Ecological and human health implications

Ecotoxicology and Environmental Safety
Microcystins (MCs), produced by harmful cyanobacterial blooms, pose a threat to aquatic ecosystems and public health in the Yangtze River basin, including Lake Chaohu, which implemented a ten-year fishing ban in 2021 for ecological restoration.

Reproductive behaviour of the ocean triggerfish Canthidermis sufflamen (Tetraodontiformes: Balistidae) in the shallow waters of the marine‐protected area of El Hierro Island (Canary Islands)

Journal of Fish Biology, EarlyView.
Abstract The abundance of Canthidermis sufflamen has increased worldwide, including around the Canary Islands, due to global ocean warming. The reproductive behaviour of this species was studied within a marine‐protected area (MPA) and its adjacent areas off the island of El Hierro (Canary Islands).

Male‐territory‐visiting polygamy in the sand‐dwelling goby Fusigobius inframaculatus (Gobiidae) inhabiting reef caves

Journal of Fish Biology, EarlyView.
Abstract We conducted an observational field survey of the innerspotted sandgoby Fusigobius inframaculatus on reefs of Kuchierabu‐jima Island, southern Japan, to investigate its mating system. Individuals of the goby maintained home ranges on sandy bottoms within rocky caves or beneath overhangs that served as shelters. Of 34 identified individuals, 32%
