Comparative Evaluation of Feeding Tiger Puffer (Takifugu rubripes) With Trash Fish and Formulated Feeds on Growth Performance, Flesh Quality, Antioxidant, and Immunity Capacity

open access: yesAquaculture Nutrition, Volume 2026, Issue 1, 2026.
This study evaluated the effects of replacing trash fish (TF) with formulated feeds in tiger puffer (Takifugu rubripes) on the growth performance, liver and serum biochemical indices, flesh quality, and metabolomics. Fish (39.6 ± 0.2 g) were fed TF, commercial feed (CF), and self‐formulated feed (SF) for 8 weeks. Results indicated that CF and SF groups

Celioscopic liver biopsy in silver catfish (Rhamdia quelen) [PDF]

open access: yesPesquisa Veterinária Brasileira, 2015
Endosurgery has been used for assessment of fish celomatic cavity, as well as for obtaining biopsies for organic analysis. Such minimally invasive access may also be used for the analysis of environmental impact on biomarkers of pollution. In Brazil, studies and literature regarding the use of celioscopy in fish are sparse.

Antioxidant Defenses in the Kidneys and Heart of the Freshwater Fish Astyanax lacustris Subjected to High (31°C) and Low (15°C) Temperatures

open access: yesCell Biochemistry and Function, Volume 43, Issue 11, November 2025.
ABSTRACT Aquatic ecosystems have their abiotic and biotic factors constantly altered by various factors. Among them, water temperature is an abiotic factor that can significantly affect fish physiology, increasing energy demand, which can impact homeostasis and survival. Endocrine and metabolic changes and enzymatic modulation are referred to as stress

New insights into the biology of the rare ectoparasitoid rhopalosomatid wasps (Hymenoptera: Rhopalosomatidae) in the Neotropics: parasitoid–host relationships in Brazil and Costa Rica

open access: yesAustral Entomology, Volume 64, Issue 4, November 2025.
Abstract Rhopalosomatidae (Hymenoptera, Vespoidea) are rare ectoparasitoid wasps that parasitize crickets (Grylloidea), with few records documented in the literature, which originate from the Nearctic and Australian regions. Here, we report the first record of Rhopalosomatidae larvae parasitizing crickets of the family Phalangopsidae in the Neotropics.
