One-year-old bay scallops, Argopecten irradians irradians (58 ± 2 mm, 22 ± 1 g live weight) were exposed to four replicated photoperiod treatments (24D, 8L:16D, 16L:8D, and 24L where D = dark hours, L = light hours) in order to measure the effect on gonad weight and maturation during the conditioning process.

Nursery culture of the bay scallop, Argopecten irradians irradians, in suspended mesh nets
Aquaculture, 1991Abstract Scallops were suspended subtidally in pyramid-shaped (pearl) nets in Long Island Sound, Milford, Connecticut, USA to assess effects of density and temperature at deployment on growth and survival. Juveniles as small as 4 mm were grown at densities ranging from 250 to 15 000/m 2 .

An inhibitor κB homologue from bay scallop Argopecten irradians
Fish & Shellfish Immunology, 2010IkappaB is an important member of NF-kappaB pathway in the innate immune system. In the present study, the full-length cDNA sequence encoding IkappaB protein (designated AiIkappaB) was isolated from bay scallop Argopecten irradians. The complete sequence of AiIkappaB cDNA containing a 5' untranslated region (UTR) of 237 bp, a 3' UTR of 1023 bp with a ...

AMPK is a key regulator of metabolism in eukaryotes across various pathways related to energy regulation. Although extensive investigations of AMPK have been conducted in mammals and some model organisms, research on AMPK in scallops is comparatively limited.

Juvenile bay scallops (7.2-26.4 mm) were exposed for 72 h to different concentrations of un-ionized ammonia, nitrite, or nitrate. Using the Trimmed Spearman Karber method, 50% lethal concentrations (LC(50)) and 95% confidence limits were calculated individually for each.

Comparative Biochemistry and Physiology Part B: Biochemistry and Molecular Biology, 2016
Bivalve mollusks lack de novo cholesterol biosynthesis capabilities and therefore rely upon dietary sources of sterols for rapid growth. Microalgae that constitute the main source of nutrition for suspension-feeding bivalves contain a diverse array of phytosterols, in most cases lacking cholesterol.

The experimental results showed that: 1) The embryonic development of bay scallop is inhibited at a dissolved oxygen range of 1.38–3.64×10−3 at 23°C, and completely blocked below the lower limit. 2) The tolerance of larvae to anoxia increased with larval sizes and was related to their oxygen debt.

Exposure of bay scallop Argopecten irradians to micro-polystyrene: Bioaccumulation and toxicity
Comparative Biochemistry and Physiology Part C: Toxicology & Pharmacology, 2020Marine microplastic pollution poses a threat to aquatic organisms, including bivalves. In this study, we investigated the accumulation of microplastics and their elicited antioxidant stress response in the bay scallop Argopecten irradians. Scallops were exposed to 1 μm diameter micro-polystyrene (MP) beads at 10, 100, and 1000 beads/mL concentrations ...

The relationships between glucose-6-phosphate isomerase (Gpi) genotype and quantitative variation related to reproduction and growth were explored over the lifespan of a single cohort of northern bay scallops, Argopecten irradians irradians (Lamarck), from September 1986 to April 1988 in the Niantic River estuary, Connecticut, USA.

Overview of Bay Scallop (Argopecten irradians) Landings
1989Bay scallops (Argopecten irradians) have been harvested along the Atlantic coast of North America since colonial times. Settlers on Cape Cod picked them up by hand at low tide (Belding 1910). In North Carolina also, shipping to northern markets in New York and Boston began as early as 1870 (Chestnut 1951).
