Diet of juvenile skipjack herring Alosa chrysochloris: Ontogenetic shifts, predator–prey size ratios and mouth gape allometry

Journal of Fish Biology, EarlyView.
Abstract The skipjack herring Alosa chrysochloris inhabits Gulf of Mexico drainages, primarily the Mississippi River Basin, and estuarine environments in the Gulf of Mexico. The trophic ecology of the skipjack herring is poorly understood, therefore we quantified the length, mouth gape and gut contents of juvenile skipjack herring from the Mississippi ...

Invertebrate communities in northern Lake Victoria, with reference to their potential for fishery production [PDF]

, 1999
The zooplankton and macrobenthic communities of Lake Victoria were sampled by lift net and Ponar grab, respectively. The zooplankton comprised copepods and cladocerans, rotifers and aquatic insect larvae. Most taxa exhibited wide distribution in the lake,

Polyphemus pediculus (L.) (Cladocera) as a possible indicator of water quality [PDF]

, 1980
Usually stenobiotic species are used as hydrobiological indicators of the degree of pollution in natural waters. Cladocera are eurybiotic organisms, therefore their role as specific indicators of the water quality is considered to be insignificant ...

Impact of Feeding Strategies on Trophic Dynamics, Growth Performance and Sustainability of Nile Tilapia in Semi‐Intensive Aquaculture Systems

Aquaculture, Fish and Fisheries, Volume 6, Issue 2, April 2026.
ABSTRACT Feed costs and limited knowledge of feeding strategies are a major constraint to the sustainability of semi‐intensive Nile tilapia aquaculture systems in sub‐Saharan Africa. In semi‐intensive systems, Nile tilapia (Oreochromis niloticus) utilizes natural pond production and supplemental feed, but their relative contributions to growth remain ...

Distribution and Biomass of the Cladocera in the Western Basin of the Anzali Lagoon (Abkenar)

‬‭Majallah-i ̒Ilmī-i Shīlāt-i Īrān, 1998
The biomass of Cladocera (Crustacea, Arthropods) and their distribution pattern in the western part of Anzali Lagoon were investigated during a one year study program in 1994. From each of the allocated sampling sites, 5 subsamples were collected using a

Zooplankton community responses to the mixture of imazethapyr with imazapic and bispyribac-sodium herbicides under rice paddy water conditions

Ciência Rural, 2014
The aim of this study was to assess the effect of concentrations of imazethapyr, imazapic, and bispyribac-sodium herbicides on zooplankton community (Cladocer, Copepod and Rotifer) in rice paddy fields. The decrease of half-life dissipation (DT50) of the

A Systematic Review of Biofloc Technology and Periphyton in Giant Freshwater Prawn (Macrobrachium rosenbergii) Aquaculture

Aquaculture, Fish and Fisheries, Volume 6, Issue 2, April 2026.
Biofloc technology and periphyton‐based systems enhance the sustainable production of giant freshwater prawn (Macrobrachium rosenbergii). A PRISMA‐guided review (2005 – 2024) shows that BFT improves survival (75 – 78 %) and feed efficiency, while periphyton supports natural productivity in grow‐out.

Exploring Cladocera Assemblage and Responses to Land Use Patterns

Diversity
Cladocera communities in surface sediments from 31 lakes in Hungary were analysed to assess the impacts of land use on the aquatic systems. We evaluated the alpha and beta diversity metrics, with land use classification types based on the Corine Land ...

Clashing in Murky Waters: On Amphibian Mosquito Suppression

Ecology and Evolution, Volume 16, Issue 3, March 2026.
This study compares the predator efficiency of common European amphibian species to common invertebrate mosquito predators. Focusing on the cosmopolitan mosquito Culex pipiens, known for transmitting pathogens like West Nile virus, we assessed predator rates, sex‐specific efficiency in amphibians, and the impact of predator presence on mosquito ...
