The Journal of Marine Research has published papers on physical, biological, and chemical oceanography vital to the academic oceanographic community for almost 80 years in the long and rich tradition of the Sears Foundation for Marine Research at Yale University. Back issues of all volumes since inception are available here and from the publisher's website. All current paid subscriptions will be honored and accessible through March 2022. Therefore, the Journal of Marine Research is no longer accepting manuscript submissions, new subscriptions, or subscription renewals for 2022. 30 loose juvenile oysters (15 spat, 15 mm shell height (SH) and 15 seed.
We regret to announce that the Journal of Marine Research-one of the oldest peer-reviewed journals in American marine science-will cease publication with Volume 79 as of December 31, 2021. An inverse relationship between mud crab size and NCE strength in the TMII. Stable as it is the accumulation of many spat falls per year over many years. These results suggest that N e may be small for a given spat fall, but the entire adult population may have large N e and is temporally Analysis of pooled adult samples across all sites suggests that N eįor the whole bay may be very large, as indicated by the large point estimates and the lack of upper confidence limits. For single sample collections, N e estimates for spat (140–440) were consistently smaller than that for adults (589–2,779). Variable, small and often without upper confidence limits. N e estimates obtained with five different methods were Comparisons of genetic diversity and relatedness among adult and spat samples failed to provide convincing evidence for strong SRS. Recruits, while the adult populations are spatially homogeneous and temporally stable. Slight genetic differences were revealed by Fst statistics between the adult populations and spat Adult and spat oysters were collected from five locations in different years and genotyped with seven microsatellite markers. To examine if SRS occurs in the eastern oyster, we studied N eĪnd genetic variation of oyster populations in Delaware Bay. The eastern oyster ( Crassostrea virginica) may be prone to SRS due to its high fecundity and high larval mortality.
In a large population may indicate high reproductive variance or sweepstakes reproductive success (SRS). N e estimates for many marine populations are small relative to the census population size. These results suggest that nutritional requirements of cultivated spat for specific fatty acids of physiological importance for marine bivalves, such as: 16:0, 16:1n-7, 18:2n-6, 20:4n-6, 18:3n-3 and 20:5n-3, were satisfied from microalgal diets with Ch-A, alone or in combination, compared with spat fed from the field culture.Effective population size ( N e) is an important concept in population genetics as it dictates the rate of genetic change caused by drift. In contrast, monoalgal diets of Tc and Ig yielded no significant differences in size and mass of spat, compared with the field culture. A significant increase in size and soft tissue mass occurred in spat fed the diets including the tropical diatom ( Chaetoceros sp.). During the field grow-out phase (field culture), samplings were performed at days 1, 15 and 30 to measure environmental variables of phytoplankton biomass (chlorophyll a), dissolved oxygen, seston, temperature and salinity. After 30 days of trial, fatty acid profiles of spat were determined along with growth in length and height shell, adductor muscle and soft tissue dry mass. (Ch-A, isolated from north-eastern Venezuela). Laboratory groups were fed with mono, binary and ternary mixtures of three cultivated algae: Isochrysis galbana (Ig), Tetraselmis chuii (Ig) and the Chaetoceros sp. We report the results of survival and growth in size and dry mass of spat of the Caribbean pearl oyster Pinctada imbricata cultivated under outdoor (field culture) and indoor (Laboratory) conditions.
