Erythrophoromas in Colored Crucian Carp, Carassius auratus [PDF]

Israeli Journal of Aquaculture - Bamidgeh, 2016
Chromatophoromas, cutaneous pigment cell tumors that originate from skin dermochromatophores of fish, amphibians, and reptiles are rarely reported. The four basic pigment cell types found in poikilothermic vertebrates are melanomas (melanophoromas), iridophoromas, xanthophoroma, and erythrophoromas.

Multi‐Seasonal eDNA Metabarcoding Highlights a Resurgence in Fish Diversity Across a Severely Impacted Estuarine Ecosystem

Aquaculture, Fish and Fisheries, Volume 6, Issue 2, April 2026.
ABSTRACT Aquatic ecosystems have been in an alarming state of decline for decades. In particular, estuarine ecosystems have experienced long‐term declines in fish diversity due to factors such as habitat degradation, pollution and altered hydrology. Monitoring these systems is often limited by the difficulty and cost of conventional survey methods.

Development and Research Progress of the ‘Land‐Based Container + Ecological Pond’ Recirculating Aquaculture Model in China

Aquaculture, Fish and Fisheries, Volume 6, Issue 2, April 2026.
This review systematically examines China's Land‐based Container + Ecological Pond (LCEP) recirculating aquaculture model. It synthesizes the system's development, technical principles, and research progress, highlighting its significant resource savings (>75% land, >90% water) and high‐density production capabilities. The analysis critically evaluates

异源四倍体银鲫外周血和精巢的组织学特征 [PDF]

, 2012
通过比较D系三倍体银鲫(Carassius auratus gibelio Bloch)与异源四倍体银鲫,我们发现异源四倍体的外周血与精巢组织跟三倍体银鲫存在明显差异。HE染色结果表明,异源四倍体银鲫外周血红细胞有明显的分裂倾向。利用流式细胞术对D系三倍体银鲫与异源四倍体银鲫外周血的DNA直方图进行比较,结果表明异源四倍体外周血的DNA直方图有两个主峰。此外,我们观察到异源四倍体银鲫精巢的三种类型,其中Ⅰ型精巢可以产生正常精子,Ⅱ型可观察到精小囊结构,但不能产生精子,Ⅲ型精巢未发育出精小囊结构 ...

Findings From the Pearl River Basin: Dissolved Oxygen Dominates Functional Trait Filtering and Diversity Patterns in Urban Rivers

Ecology and Evolution, Volume 16, Issue 4, April 2026.
Urbanization reshapes fish communities via environmental filtering. Surveying 44 sites across an urban (Huadi) and a relatively natural (Zengjiang) river in the Pearl River Basin (2024), we linked environmental variables to fish functional traits using RLQ and SEM, finding that dissolved oxygen is the dominant filter in urban reaches—selecting low ...

Comparative analysis of morphology, growth performance and gonadal development between the hybrid crab (Scylla serrata ♀ × S. paramamosian ♂) and S. serrata

Journal of the World Aquaculture Society, Volume 57, Issue 2, April 2026.
Abstract Interspecific hybridization, through integrating genetic resources across distinct species, serves as a pivotal strategy for improving yield, stress resistance, and quality in aquacultural species. To evaluate the performance of hybrid crab (Scylla serrata ♀ × S.

Optimal dietary protein level for juvenile Hefang crucian carp (Carassius auratus): Balancing growth performance and hepatic health

Journal of the World Aquaculture Society, Volume 57, Issue 2, April 2026.
Abstract A 54‐day feeding trial was conducted to investigate the effects of dietary protein levels on growth performance, digestive capacity, plasma biochemical indexes, and gene expression in Hefang crucian carp (Carassius auratus). Six experimental diets were prepared with protein levels of 21.7%, 24.0%, 29.4%, 34.0%, 38.0%, and 43.2%, respectively ...

Modulation of the effectiveness of 17-alpha-hydroxy-20-beta-dihydroprogesterone or of a gonadotrophic extract on the in vitro intrafollicular maturation of oocytes of the rainbow trout Salmo gairdnerii by various non-maturing steroids [Translation from: Compte Rendu Hebdomadaire des Seances de l'Academie des Sciences, Paris, Series D 281, 811-814, 1975] [PDF]

, 1980
The effectiveness of 17 α-hydroxy-20 β-dihydroprogesterone (17 α-20 β Pg) or of a trout hypophyseal gonadotrophic extract on the in vitro intrafollicular maturation of trout oocytes can be modulated by steroids which do not have a direct maturing effect;
