The combined effects of salinity and temperature on survival and growth of larvae of the mussel Mytilus edulis (L.) were studied. The effects of salinity and temperature are significantly related only as the limits of tolerance of either factor are approached. Survival of larvae at salinities from 15 to 40‰ is uniformly good (70% or better) at temperatures from 5° to 20°C, but is reduced drastically at 25 °C, particularly at high (40‰) and low (20‰) salinities. Larval growth is rapid at a… 

Combined effects of temperature and salinity on fed and starved larvae of the European flat oyster Ostrea edulis

Combined effects of temperature, salinity and nutrition on larval survival and growth of the European oyster Ostrea edulis L. were studied over a period of seven days in the laboratory. Larvae were

The combined effects of temperature and salinity on embryos and larvae of the black-lip pearl oyster, Pinctada margaritifera (L.)

The combined effects of temperature and salinity on embryonic development and growth and survival of black-lip pearl oyster, Pinctada margaritifera (L.) larvae were examined to find the optimal conditions for maximum survival and growth.

Combined effects of temperature and salinity on embryos and larvae of the northern bay scallop Argopecten irradians irradians

It is suggested that northern bay scallop embryos and larvae be reared at their respective optimal temperature-salinity levels so as to increase efficiency of aquaculture operations.

Effects of temperature and salinity on the life cycle of Ophryotrocha diadema (polychaeta, dorvilleidae)

Ophryotrocha diadema is stenohaline and the complete life cycle has only been observed at salinities of 30, 35 and 40 ‰, where reproduction occurs between 11 and 27 °c and growth rate was observed at 30 and 35 ‰ salinity and 25°C.

A response-surface approach to the combined effects of temperature and salinity on the larval development of Adula californiensis (Pelecypoda: Mytilidae). I. Survival and growth of three and fifteen-day old larvae

Temperature and salinity ranges for maximum survival were narrower than the ranges which occur within the estuary where the adult populations exist, and no statistically significant temperature-salinity interaction was found for either survival or growth.

Effect of temperature on survival, growth and development of Mytilus galloprovincialis larvae

Temperature treatments on Mytilus galloprovincialis larvae under laboratory conditions produced better growth, higher survival rates and faster metamorphosis as compared with 17 °C, and implications of these results on the development of commercial hatcheries were discussed.

It is suggested that acclimation of the shell growth of M. edulis to salinities in the 12·8–28·8‰ S range was achieved by the mussels during the experimental period.

GENETIC ASPECTS OF LARVAL GROWTH UNDER REDUCED SALINITY IN MYTILUS EDULIS

The genetic analysis indicated substantial genetic variation in larval length measured 16 days after fertilization, as well as significant genetic interaction with salinity interpreted as the presence of genes influencing larval growth which depend on salinity for their expression and may be related to the past selective influence of a fluctuating environment.

A REEVALUATION OF THE COMBINED EFFECTS OF TEMPERATURE AND SALINITY ON SURVIVAL AND GROWTH OF BIVALVE LARVAE USING RESPONSE SURFACE TECHNIQUES

The combined effects of temperature and salinity on larval survival and growth of Crassostrea virginica, Mercenaria mercenaria, and Mulinia lateralis were critically examined using response surface techniques.

TEMPORAL CHANGES IN THE SALINITY AND TEMPERATURE REQUIREMENTS OF TROPICAL MUSSEL LARVAE

A generalized model for the growth responses of tropical mussel larvae is developed which is presented as a motion picture study of the changing responses to temperature and salinity.

INDIVIDUAL AND COMBINED EFFECTS OF SALINITY AND TEMPERATURE ON EMBRYOS AND LARVAE OF THE COOT CLAM, MULINIA LATERALIS (SAY).

Growth of larvae was most rapid within the salinity range from 20 to 35‰ and within the temperature range from 22.5 to 27.5° C and atSalinity and temperature were significantly related only when the tolerance of either one or the other was approached and, conversely, when both salinity andTemperature were within the satisfactory range there was no significant interrelationship.

The rate of growth of Mytilus larvae increased with increased temperature from 10–18° C, but from 13–13° C the growth was relatively temperature-independent, and at temperatures higher than 18° C larvae from a littoral area grew at a slightly increased rate, but larvae from an sub-littoran area showed decline of the growth rate.

K Kraft mill effluent is a very effective material in stimulating spawning in the mussels M. edulis and M. californianus, and electrical stimulation of intact mussels was also shown to stimulate spawning, but was not as effective as KME.
