Environmental enrichment with aquatic plants: Impact of the environment of choice on performance of bettas

This study aimed to evaluate the choice between environments with aquatic plants and the impact of the environment of choice on the performance of bettas (Betta splendens). First, the choice between environments with natural and artificial plants was evaluated. Adult...

The maintenance conditions of the zebrafish (Danio rerio) breeding stock affect the survival and behavior of their offspring

The environment in which we live influences our biological traits throughout our ontogeny, being markedly significant during the beginning of our lives. Some characteristics inherited (genetically and/or epigenetically) from parents can also influence individual development, known as transgenerational effects. In...

Recovery of male Siamese fighting fish (Betta splendens) after overland shipping

Ornamental fish shipped by road or rail may spend days in transit without food, leading to a reduction in somatic growth after transportation and during acclimatization. In the present study, a time-series (0, 2, 4, 6, 8, 10, and 12...

How does food enrichment and the presence of visitors affect the behaviour of two species of freshwater fish in a public aquarium?

Food-based environmental enrichment (EE) is a valuable strategy for stimulating foraging behaviour in fish under human care, as it increases the challenge of food acquisition and encourages prolonged engagement in this activity. Curimbas (Prochilodus argenteus) and pacus (Myleus micans) are...

Editorial: Fish welfare in aquaculture and research—where are we going?

Rapid technical developments are taking place in aquaculture, and its production is increasing globally every year by more than 4%. Research is the necessary foundation for politics to define reasonable regulations and recommend guidelines for aquaculture, but also the basis...

Evaluating the suitability of substrate enrichment for Zebrafish in high-capacity research aquaria

Zebrafish, Danio rerio, show a preference for substrate enrichment within their tanks however this is seldom included within high-capacity research aquaria due to fears its inclusion may impact on their ability to breed on demand. To investigate this potential impact...

Pre-transport salt baths mitigate physiological stress and tissue damage in channel catfish (Ictalurus punctatus) fingerlings: evidence from multi-biomarker assessment and histopathology

Effective transport strategies are critical for the survival and welfare of juvenile Ictalurus punctatus, but the effects of pre-transport salt bath treatments remain uncertain. In this study, we systematically evaluated the effects of pre-transport salt bath acclimation at 0‰ (S1),...

From Fish to Mice to Monkeys in Research: Challenges and Opportunities for Mental Well-being

This chapter focuses mainly on animals in medical research. Many, especially the smaller species such as rat, mice, and zebrafish, may be seen only a few minutes a day by their human caregivers. Most laboratory animals are kept in confinement...
