Crustacean and Mollusc Shell Proteins: Origin, Structure, and Functionality
ABSTRACT Crustacean and molluscan processing as seafood generates a significant amount of shell waste annually, owing to the dense, mineral‐rich composition of the exoskeleton. Although valorization efforts have mostly focused on chitin and chitosan, the protein fraction remains underutilized despite its prominent nutritional, functional, and sensory ...

Cryopreservation has been widely employed to preserve genetic material of aquatic animals. Although of common use in bivalves, resulting effects due to the toxicity of the cryoprotectants dimethyl sulfoxide (DMSO), propanediol (PG), methanol (MET) and ethylene glycol (EG), upon sperm motility in the Chinese pearl oyster, Pinctada fucata martensii, has ...

Settlement and metamorphosis are key developmental hurdles in marine mollusk aquaculture. Environmental signals (such as biofilms, algae, and signals from conspecifics) and biochemical pathways (including nitric oxide, thyroid hormones, catecholamines, and GABA) regulate the transition of larvae into benthic juveniles. Combining ecological observations

Delaware Inland Bays and Market Oyster (Crassostrea virginica) Quality for Consumption
Consumption of raw oysters is known to cause serious health conditions due to bioaccumulation of contaminants. As filter feeders, oysters ingest bacteria along with phytoplankton from their surrounding habitats. Ensuring seafood safety for human consumption is always a concern.

Chromosome complement of the Indian pearl oyster Pinctada fucata (Gould) [PDF]
The chromosome number (n = 14, 2n = 28) of the Indian pearl oyster Pinctada fucata (Gould) is reported for the first time. It conforms with *he chromosome number reported for P. fucata martensii from Japan and P. imhricata from the Atlantic.

Mapping molluscan endocrinology: a systematic and critical appraisal
ABSTRACT Historically, a vertebrate‐centric paradigm has framed our interpretation of molluscan endocrinology, with considerable research focusing on vertebrate‐type steroid hormones (e.g. oestrogens, testosterone). However, contradictory evidence on the occurrence of vertebrate‐type steroid hormones in molluscan tissues, and a lack of the specific ...

The types of tissues accumulating glycogen and seasonal changes in glycogen content were investigated in the following shell species: pen shell Atrina lischkeana, ark shell Scapharca kagoshimensis, and Manila clam Ruditapes philippinarum. Comparison of the results showed that the adductor muscle or foot was the main glycogen reservoir and the levels ...

Tyrosinase plays an important role in the formation of the shell matrix and melanin synthesis in mollusks shells. A cDNA clone encoding a 47 kDa protein was isolated from the pearl oyster Pinctada fucata. The cDNA was 1,957 base pairs long and encodes a 417 residue protein that has extensive sequence identity with tyrosinase (polyphenol oxidase: EC 1 ...
