Cuticle-degrading Enzymes of Entomopathogenic Fungi: Regulation of Production of Chitinolytic Enzymes [PDF]

Microbiology, 1986
Summary: Synthesis of chitinase and chitosanase by the entomopathogenic fungus Metarhizium anisopliae is regulated by products of chitin and chitosan degradation through an inducer-repressor mechanism. Slow-feeding with sugars or alanine (about 20 μg ml−1 h−1) in a carbon deficient medium to prevent catabolite repression (restricted cultures ...

A Novel Crustavirus as a Candidate Aetiology of Tail Fan Necrosis in New Zealand Red Rock Lobsters, Jasus edwardsii

Journal of Fish Diseases, Volume 49, Issue 2, February 2026.
ABSTRACT Tail fan necrosis (TFN) is a shell disease affecting spiny lobsters' outer integument, with significant implications for the health and commercial viability of red rock lobsters (Jasus edwardsii) in New Zealand. Despite its impact, the potential role of a microbial agent in TFN remains poorly understood.

Effects of Dietary Calcium and Magnesium Levels on the Growth Performance, Tissue Mineral Deposition, Exoskeleton Development, and Molting Performance of Chinese Mitten Crab (Eriocheir sinensis)

Aquaculture Nutrition, Volume 2026, Issue 1, 2026.
Calcium and magnesium are essential mineral elements for animal growth and development, playing crucial roles in skeletal formation, particularly in the molting process of crustaceans. However, their interaction is still poorly elucidated. This study investigated the effects of dietary calcium and magnesium levels on the growth performance, tissue ...

Combined Substitution of Fishmeal and Fish Oil With Black Soldier Fly Larval Meal and Corn Oil: Effects on Growth, Hematology, Hematobiochemical, Amino and Fatty Acid Composition, and Fillet Nutritional Quality of Hybrid African Catfish Clarias gariepinus × Heterobranchus longifilis

Aquaculture Nutrition, Volume 2026, Issue 1, 2026.
This study aimed to evaluate growth performance, amino acid and fatty acid composition of fillets, and blood biochemistry of hybrid catfish (Heteroclarias) cultured on Black Soldier Fly (BSF), Hermetia illucens larval‐based diets. The experiment was conducted in a recirculating system, circular poly tanks (350 L), in a completely randomized design ...

Dietary Hermetia illucens Larvae Meal Enhances Growth Performance, Intestinal Health and Modulates Intestinal Microbiota of Juvenile Mirror Carp (Cyprinus carpio)

Aquaculture Research, Volume 2026, Issue 1, 2026.
As global aquaculture expands, sustainable alternative feed ingredients are needed to reduce reliance on fishmeal (FM) and conventional plant proteins. Herein, this study evaluated defatted black soldier fly (BSF; Hermetia illucens) larvae meal as a replacement mainly for soybean meal (SBM) and soy protein concentrate (SPC) in juvenile mirror carp ...
