Salzwedel (1979) studied a population of Fabulina fabula (studied as Tellina fabula) from the German Bight. Peak abundance (ca 2000 individuals/m²) occurred in September following the main period of spatfall and then decreased to a minimum in February (ca 500 individuals/m²), at which point settlement began to occur again. The mean annual abundance was approximately 1000 individuals/m². Lopez-Jamar et al. (1995) reported the mean abundance of Fabulina fabula (studied as Tellina fabula) from La Coruna Bay in NW Spain to be 897 individuals/m², with a maximum abundance of 1871/m². Warwick et al. (1978) studied the Venus community from very fine sand in Carmarthen Bay, Bristol Channel. They reported Fabulina fabula (studied as Tellina fabula) densities of 80 individuals/m² and biomass of 340 mg/m².
Size at maturity
Growth rate of Fabulina fabula appears to be highly dependent on environmental conditions. Withers (1977) recorded spatfall of Fabulina fabula (studied as Tellina fabula) at Oxwich in Wales. 14 months after settlement, individuals had grown to lengths between 5.5 mm and 11 mm. However, growth may not be so rapid and Muus (1973) described Fabulina fabula from Øresund as attaining lengths of 3-4.5 mm after 21 months. Under laboratory conditions, Salzwedel (1979) recorded maximum growth of Fabulina fabula (studied as Tellina fabula) to be 10.3 mm in one year or 15.7 mg of dry tissue weight. Mean daily growth over the course of a year was a 0.40% increase in shell length. Salzwedel (1979) also noted 3 annual minima in growth rates which corresponded with the growth rings on the outside of the shell.
