“…In Wadden Sea Macoma balthica, we did not observe sex-dependent differences in gonad weights, nor did Harvey & Vincent (1989) observe differences in sexual-product weights between male and female M. balthica in the St. Lawrence estuary. Thus, although only eggs were used in the calculations of gamete output, the results are presumed to apply to both sexes.…”

The number of eggs produced in the annual spawning season by an adult female Macoma balthica (L.) of Wadden Sea origin increases in a non-linear manner with increasing shell length and body weight. It depends primarily on the weight-at-length immediately before spawning. Lean individuals with a low body-mass index (BMI) of 5.6 mg cm -3 or less spawn no eggs. Gamete output increases to about one-third of soft-body weight (in the order of 100 000 eggs) at the maximal BMIs observed (~15 mg cm ). Annual growth was also significantly lower in years starting with a low BMI value. Because spawning lowers body weight and thus the BMI, spawning is bound to reduce subsequent survival rates and body-weight increments. Thus, a trade-off situation exists between immediate and future spawning outputs. The consequences for total lifetime egg production of various levels of gamete output at first spawning (at an age of 2 yr) were estimated by model calculations, starting from a wide range of body weights at a standard length. The model results realistically predict that maximal lifetime egg production can be achieved only if M. balthica refrain from spawning at BMIs below a certain threshold value (viz. ~6 mg cm

“…Individuals staying in the upper zone would soon experience difficulties with their energy balance, as judged from the low growth rates and reproductive outputs (cf. Harvey & Vincent, 1989). If high numbers stayed in the upper zone, the situation would become even worse by negative density effects, as Vincent et al (1989) observed -particularly in the upper parts of the intertidal zone.…”

“…8}. In the St. Lawrence estuary, Harvey & Vincent (1989 also observed more rapid growth at lower elevations, but Green {1973) and Bachelet {1980) found the reverse relationship in the Hudson Bay and the Gironde estuary, respectively. Local conditions and way of feeding appear to be important.…”

“…In the Balgzand area, adult h4acoma appear to obtain most of their food from the overlying water and not from the sediment surface (Hummel, 1985;Kamermans, 1992). R e p r o d u c ti o n. In the St. Lawrence estuary, Harvey & Vincent (1989) observed that Macoma hying at lower intertidal levels produce more gametes than those hying at higher levels. Gamete production in this area is largely assured by the small populations living low in the intertidal.…”

Successive changes in distribution patterns as an adaptive strategy in the bivalveMacoma balthica (L.) in the Wadden sea

During their first year in the Wadden Sea, high proportions of the tidal-flat populations of the telhnid bivalve Macoma balthica (L.) redistribute twice: immediately after their settlement in late spring, the postlarvae show a net transportation in a shoreward direction -whereas in the subsequent winter, the grown spat move in the reverse direction. As a consequence of these two periods of high mobihty, distribution patterns shift twice: though initial settlement takes place mainly in the lower half of the intertidal, most spat grow to a size of ~-0.5 cm in the upper half of it, whereas most adults live in the middle and lower zones. The successive distribution patterns of spat and older Macoma are described in detail for Balgzand, an extensive tidal-flat area in the westernmost part of the Wadden Sea. Long-term observations in this area and pubhshed evidence from other areas are used to evaluate the suitability of different tidal zones as a habitat for successive life stages of Macoma. For spat, the upper zone is a more favourable habitat than the lower, because predation pressure (mainly from shrimp) and disturbance are less and growth is more rapid. For adults, the upper parts are no longer a favourable habitat, because the few animals that stay suffer from high parasite load, low survival, slow growth and low reproductive output, tt is concluded that in their successive life stages the majority of M. balthica live at the intertidal level most favourable to them. The strategy of timely shifts tO areas more suitable to the next life stage contributes to the success of the species: it is the most widespread and common (and one of the most stable) macrozoobenthic species in the Wadden Sea.

“…In modular organisms, such as plants and corals, in which size and age are not always correlated, it has been often reported that size is more important than age in determining population dynamics and reproductive traits (Werner & Caswell 1977, Chapman 1986, Ang 1991, Babcock 1991, but see Hughes & Connell 1987. However, only a few studies have examined independent effects of size and age on the life history pattern of solitary animals, including marine bivalves (Kautsky 1982, Peterson 1983, Harvey & Vincent 1989. Nevertheless, some vital traits of bivalve populations, especially mortality, are strongly dependent on size (Hughes 1970, Paine 1976, Blundon & Kennedy 1982, Goshima 1982, Peterson 1982a, b, Arnold 1984, Juanes 1992, Zwarts & Blomert 1992.…”

Between-site variation in age and size at maturity, egg size, fecundity and reproductive effort was measured in a population of the bivalve Yoldia notabilis in Otsuchi Bay, northeastern Japan, and tests were conducted to address whether these reproductive traits are dependent on size or age. The diameter of mature oocytes increased with age and size, as did fecundity and reproductive effort. Most individuals were mature at 3 yr of age (Age 3) at the shallower station (10 m depth) and at Age 4 at the deeper station (14 m), although the size at maturity was similar (between 15 and 20 mm shell length) at the 2 stations. This is the size at which the bivalve escapes heavy predation from the crab Paradorippe granulata. Age-specific reproductive effort was higher at the shallower station than at the deeper one; however, reproductive effort did not differ significantly between stations when compared on the basis of size. These lines of evidence suggest that the onset of reproduction and the schedule of reproductive effort depend more on size than age. The observed size-dependency of reproduction is considered to be associated with size-dependent mortality rate due to predation, as well as with slzelimited reproductive capacity due to morphological constra~nts in shell volun~e.
