Fish welfare in a changing world: New developments and current challenges

Journal of Fish Biology, EarlyView.
Abstract The welfare of non‐human animals is central to ethical discussions on animal use, with increasing attention to fish welfare across research, aquaria, aquaculture, and fisheries. This paper reviews current theoretical approaches to animal welfare and recent advances in defining and assessing fish welfare since the seminal paper by Huntingford ...

Sexual selection and reproductive success in mesocosm populations of African annual killifish

Journal of Fish Biology, EarlyView.
Abstract Variation in individuals’ ability to obtain mates generates sexual selection, which typically acts more strongly on males and can produce pronounced differences in phenotypes between the sexes (i.e., sexual dimorphism). The dynamic of sexual selection and individual reproductive success is considerably affected by the availability of ...

Case-Building Behavior, Persistence, and Emergence Success of \u3ci\u3ePycnopsyche Guttifer\u3c/i\u3e (Walker) (Trichoptera: Limnephilidae) in Laboratory and \u3ci\u3ein situ\u3c/i\u3e Environments: Potential Trade-Offs of Material Preference [PDF]

, 2018
When removed from their cases in a non-flow laboratory environment, 5th instar Pycnopsyche guttifer (Walker) larvae were always successful in constructing a new case within 24 h when woody debris was present as a material choice.

Haematological and histopathological monitoring of monosodium glutamate–supplemented feeding in rainbow trout (Oncorhynchus mykiss): A possible modelling for a single health approach

Journal of Fish Biology, EarlyView.
Abstract The aim of this study was to investigate the potential effects of monosodium glutamate (MSG), a known flavour enhancer added to many ready‐to‐eat foods, as a feed additive in rainbow trout (Oncorhynchus mykiss). Evaluating the effects of MSG on aquatic organisms will fill the knowledge gap in this field by monitoring the haematological indices

St John's Wort (Hypericum perforatum) Oil on Immune Response, Growth Performance and Bacterial Resistance Against Lactococcus garvieae Pathogen in Rainbow Trout (Oncorhynchus mykiss)

Journal of Fish Diseases, EarlyView.
ABSTRACT In this study, we investigated the immunomodulatory effects of St. John's Wort (Hypericum perforatum) oil on the growth performance, immune responses and resistance against Lactococcus garvieae in rainbow trout (Oncorhynchus mykiss). The plant oil was incorporated into feeds at concentrations of 1, 3, and 5 g kg−1, designated as K1, K3, and K5,

Intraspecific Variation in the Characteristics of Cryptocaryon irritans Isolated in Japan

Journal of Fish Diseases, EarlyView.
ABSTRACT Cryptocaryon irritans is an obligate parasitic ciliate and the causative agent of cryptocaryoniasis. This parasite is widely distributed in tropical and subtropical marine waters, and numerous outbreaks in aquaculture have been reported worldwide. Previous studies have documented variations in biological traits, such as cell size, serotype and

The dental plate on bichir pectoral fins: A unique dermal skeletal element bearing individual odontodes with tooth‐like replacement

Journal of Anatomy, EarlyView.
Pectoral fins of bichirs encompass the so‐called dental plates – unique dermal skeletal elements with individual odontodes identical to the oral teeth. Abstract The dermal skeleton appeared early in vertebrate evolution in the form of mineralized skin denticles composed of tooth‐like units—odontodes.
