Antagonistic activity of cellular components of Pseudomonas species against Aeromonas hydrophila [PDF]

open access: yes, 2006
Antagonistic effects of Pseudomonas fluorescens, P. aeruginosa and P. putida were studied against 12 strains of Aeromonas hydrophila (Ah1–Ah12). Four different fractions of cellular component (i.e.

Key species drive community and functional stability of segment‐specific gut microbiomes after the swimming crab molting

open access: yesiMetaOmics, Volume 2, Issue 1, March 2025.
Molting is a crucial process for crab growth and development. However, the impacts of molting on the structure and function of the gut bacterial community in swimming crab Portunus trituberculatus are poorly understood. Then, dynamic changes in the microbiotas of gut segments (foregut, midgut, and hindgut) after molting were investigated using 16S rRNA

Nutritional value and biochemical composition of two new tropical polychaete species: Potential use as feed ingredients

open access: yesJournal of the World Aquaculture Society, Volume 56, Issue 1, February 2025.
Abstract Polychaetes are a promising intertidal resources due to their widespread distribution, considerable biomass, and high nutrition value. The nutritional profiles of two novel tropical polychaetes species (Marphysa sp. and Halla sp.) were determined.

Identification, cellular localization, and function analysis of a novel toll‐like receptor (PtToll4) in Portunus trituberculatus

open access: yesJournal of the World Aquaculture Society, Volume 56, Issue 1, February 2025.
Abstract Toll‐like receptor (TLR) is one of the most important pattern recognition receptors in both invertebrate and vertebrate animals. In previous study, three different kinds of TLR cDNAs (PtToll1‐3) have been cloned from Portunus trituberculatus. In this study, a novel PtToll4 cDNA sequence was identified in this crab. The PtToll4 ORF is predicted

Optimal Tryptophan Improved Growth and Regulated Agonistic Behavior of Oriental River Prawn, Macrobrachium nipponense

open access: yesAquaculture Nutrition, Volume 2025, Issue 1, 2025.
Tryptophan, recognized as the third limiting amino acid, plays a crucial physiological function. The optimal tryptophan requirement for oriental river prawn (Macrobrachium nipponense) was assessed, and its impact on agonistic behavior was evaluated in this study. An 8‐week feeding trial was implemented with six different tryptophan levels: 0.07%, 0.17%,

Physiology of Ovarian Development in Crustaceans: Interactions Among Hormones, Nutrients, and Environmental Factors From Integrated Perspectives

open access: yesAquaculture Nutrition, Volume 2025, Issue 1, 2025.
Reproductive maturation remains a central bottleneck in crustacean aquaculture, as ovarian development dictates broodstock quality, fecundity, and larval viability. This review synthesizes current knowledge on the physiological regulation of ovarian maturation in decapod crustaceans, emphasizing the interplay of hormones, nutrients, and environmental ...
