Enrichment of nutrition of Brachionus spp. in the tropical areas [PDF]

open access: yes, 2020
Larvae feeds incorporating Brachionus spp. play a great role in fish cultivation. However, the development and nutritional content of Brachionus spp. depends on the nutrient enrichment provided.

Comparing the Effects of Microplastics From Conventional Cigarette Butts and Heated Tobacco Device: The Role of UV‐Induced Aging

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Despite the widespread presence of cigarette butts in the environment, the potential toxicological effects posed by microplastics (MPs) derived from them remain poorly understood. In this study, we compared the effects of MPs from conventional cigarette butts (cellulose acetate) and heated tobacco devices (cellulose acetate and polylactic acid

Linking genome size variation to population phenotypic variation within the rotifer, Brachionus asplanchnoidis

open access: yesCommunications Biology, 2021
Claus-Peter Stelzer et al. take advantage of genome size variation within a natural population of the rotifer, Brachionus asplanchnoidis, to investigate the effects of genome size on phenotypic correlates, such as cell size and development time.

Continuous darkness is associated with improved growth performance during a high‐temperature period and sex‐specific modulation of early gonadal development in juvenile yellowtail (Seriola quinqueradiata)

open access: yesJournal of Fish Biology, EarlyView.
Abstract Selective breeding of yellowtail (Seriola quinqueradiata) is expanding in Japan, increasing the demand for practical reproductive control tools in commercial aquaculture to reduce genetic risks from escapees. Slowing early gonadal development through environmental manipulation may support future sterilization strategies, particularly when ...

Embryonic and larval development of the endangered Chiapas killifish Tlaloc hildebrandi (Cyprinodontiformes: Profundulidae)

open access: yesJournal of Fish Biology, EarlyView.
Abstract The early ontogeny of endemic freshwater fishes provides essential baseline biological information for conservation and management, particularly in species with restricted distributions and high vulnerability to habitat degradation, environmental change and population decline. This study presents the first detailed description of embryonic and

Possible involvement of hemolytic activity in the contact-dependent lethal effects of the dinoflagellate Karenia mikimotoi on the rotifer Brachionus plicatilis [PDF]

open access: yes, 2010
We investigated the effects of two strains (SUO-1 and FUK) of the dinoflagellate Karenia mikimotoi on the rotifer Brachionus plicatilis. The SUO-1 strain was highly toxic to rotifers, whereas the FUK strain was less toxic.

Enrichment‐Based Duplex PCR for Early Detection of Potentially Virulent Vibrio harveyi in Aquaculture

open access: yesJournal of Fish Diseases, EarlyView.
ABSTRACT Vibrio harveyi is an important bacterial pathogen in marine aquaculture, responsible for outbreaks affecting a wide range of fish species. Early detection of potentially virulent isolates in fish and environmental samples is essential for effective disease prevention and management, particularly under field conditions where the pathogen may be
