Impact of fishmeal replacement with Arthrospira platensis on growth performance, body composition and digestive enzyme activities of the freshwater prawn, Macrobrachium rosenbergii

open access: yesAquaculture Reports, 2016
In this study, we assessed the suitable level of replacement of fishmeal with a blue green microalga, Arthrospira platensis in feed for the post larvae (PL) of the freshwater prawn, Macrobrachium rosenbergii by evaluating the growth performance, prawn ...

Crustacean hematopoiesis

open access: yesDevelopmental & Comparative Immunology, 2016
Crustacean hemocytes are important mediators of immune reactions, and the regulation of hemocyte homeostasis is of utmost importance for the health of these animals. This review discusses the current knowledge on the lineages, synthesis and differentiation of hemocytes in crustaceans.

Sublethal Biochemical Effects of Polyethylene Microplastics and TBBPA in Experimentally Exposed Freshwater Shrimp Palaemonetes argentinus

open access: yesBiology, 2023
The biochemical effects of sublethal exposure to polyethylene microplastics (PEM) of 40–48 µm particle size and the flame retardant tetrabromobisphenol A (TBBPA), a plastic additive, on the freshwater shrimp Palaemonetes argentinus were assessed.

The lack of genetic variation underlying thermal transcriptomic plasticity suggests limited adaptability of the Northern shrimp, Pandalus borealis

open access: yesFrontiers in Ecology and Evolution, 2023
IntroductionGenetic variation underlies the populations’ potential to adapt to and persist in a changing environment, while phenotypic plasticity can play a key role in buffering the negative impacts of such change at the individual level.MethodsWe ...

Horizontal transfer of parasitic sex ratio distorters between crustacean hosts [PDF]

open access: yes, 1998
Parasitic sex ratio distorters were artificially transferred within and between crustacean host species in order to study the effects of parasitism on host fitness and sex determination and to investigate parasite–host specificity. Implantation of Nosema

SOMATIC GROWTH OF THE MUDFLAT FIDDLER CRAB Uca rapax (Smith, 1870) (Brachyura: Ocypodidae) FROM TWO SUBTROPICAL MANGROVES IN BRAZIL

open access: yesEcosistemas y Recursos Agropecuarios, 2014
The crabs were collected monthly, from April 2001 to March 2002 in the mangroves of Itamambuca and Ubatumirim in Ubatuba, São Paulo, Brazil, using the procedure of catch per unit effort (cpue) during 15 minutes at low tide periods by digging the burrows.

Comment: Food web interactions and biomanipulation in Australian reservoirs [PDF]

open access: yes, 1997
The authors have been studying the control of phytoplankton biomass in several Australian reservoirs. To manipulate fish communities in order to reduce phytoplankton biomass, one needs a thorough understanding of processes in the plankton-associated food
