TLDR
Crassostrea gigas (Thunberg) and Ostrea edulis L. were grown at sustained temperatures of 12°, 15°, 18° and 21°C for a period of 19 weeks.Abstract:
Crassostrea gigas (Thunberg) and Ostrea edulis L. were grown at sustained temperatures
of 12°, 15°, 18° and 21°C for a period of 19 weeks. Regular assays of weight specific ammonia excretion rate were made, following which animals were sacrificed for estimation of dry meat weight, dry shell weight, biochemical composition (percentage carbon, nitrogen, carbohydrate, ash) and gonadal development (histological assessment). Crassostrea gigas grew from an intial live weight of 5·2 g to values of 23·5, 28·2, 34·6 and 38·7 g at 120, 150, 180 and 21 °C respectively.read more

Seventy years' observations of changes in distribution and abundance of zooplankton and intertidal organisms in the western English Channel in relation to rising sea temperature
TL;DR: In this paper, the authors studied changes in marine communities in southwest Britain and the western English Channel during the past 70 years and found that the distribution of both plankton and intertidal organisms was affected, with latitudinal shifts of up to 120 miles; there were increases or decreases of 2-3 orders of magnitude in abundance.

The use of physiological condition indices in marine bivalve aquaculture
Albert Lucas,Peter G. Beninger +1 more
TL;DR: The dynamic indices reviewed are based on production estimates, and hence reflect physiological changes over specified time intervals, and only net growth efficiency is recommended for use in bivalve aquaculture, and it is applicable to all life stages.

Developmental and Seasonal Metabolic Activities in Marine Molluscs
TL;DR: Developmental and seasonal metabolic activities in marine mollusks are a reflection of the complex interactions between food availability, temperature, growth, and reproductive activities and it seems unlikely that there will be a significant contribution from anaerobic metabolism in bivalve larvae.

The Assessment of Marine Pollution - Bioassays with Bivalve Embryos and Larvae
TL;DR: Bioassays have increasingly come into use during the past three decades and are now commonly employed to ascertain the biological effects of pure chemicals, as well as to determine the quality of effluents, coastal waters and sediments sampled in the field.

Introduced Pacific oysters (Crassostrea gigas) in the northern Wadden Sea: Invasion accelerated by warm summers?
TL;DR: It is concluded that the further invasion of C. gigas in the northern Wadden Sea will depend on high late-summer water temperatures, which coincide with above-average temperatures in July and August when spawning and planktonic dispersal occurs.

The Influence of Current Speed, Body Size and Water Temperature On the Filtration Rate of Five Species of Bivalves
TL;DR: In this article, the rate of water filtration by bivalves has long excited interest, but it has in practice proved difficult to measure in conditions where the animal is relatively free from constraint.
