“…Several authors noticed that bivalve recruit densities found in coastal areas in summer vary strongly from year to year and that recruitment success may be related to the temperature of the preceding winter, with the most successful recruitments occurring after the coldest winters (Möller & Rosenberg 1983, Jensen & Jensen 1985, Beukema 1992a, Beukema et al 2001, 2009, Strasser et al 2001a, 2003, Strasser 2002. Results of the present study corroborated the negative relationship between winter temperatures and recruit densities in the following summer for all 4 bivalve species studied, in 3 of them significantly so (Table 1).…”

“…Review papers by Peterson (1979) and Reise (1985b) include numerous examples of early experiments with essentially similar results. Several more recent studies showed strong effects of predator exclusion on bivalve recruitment success as well (Mattila et al 1990, Fernandes et al 1999, Richards et al 1999, Beal et al 2001, Hiddink et al 2002, Hunt & Mullineaux 2002, Strasser 2002, Flach 2003, Van der Heide et al 2014, all suggesting that substantial reduction of bivalve recruitment by epibenthic predation is a generally occurring phenomenon. Results from detailed laboratory experiments (Andresen & Van der Meer 2010) strengthen the interpretation of results from cage experiments.…”

“…Reduction in cockle recruitment success by high predation rates and the presence of high densities of adult macrofauna led to recruitment failures (Beukema and Dekker, 2005;Flach, 2003). Predation of larval cockles by adult cockles through larviphagy can lead to reductions of up to 40% of the population (Andre and Rosenberg, 1991;Malham et al, 2012).…”

The cockle Cerastoderma glaucum represents one of the most common marine mollusc species present in Egyptian waters. This study aims to investigate the population structure, growth, mortality, and exploitation status of this cockle along Lake Qarun and Lake Timsah in order to make a comparison study. Cockles were collected from Lake Qarun at monthly intervals between February 2008 and May 2009 and collected from Lake Timsah at four seasons only. Length frequency data were analyzed using FiSAT software for estimation of population parameters to evaluate the stock. Asymptotic length (L∞) was smaller in Lake Qarun (28.35 mm) compared to that in Lake Timsah (33.60 mm).Growth coefficient (K) was higher in Lake Qarun (0.450 yr -1 ) than in Lake Timsah (0.280 yr -1 ).Growth performance index (Φ) values were similar (2.56) in both cockle stocks. The theoretical maximum age (Tmax) was higher in Lake Timsah (12.6 yr -1 ) than in Lake Qarun (7.4 yr -1 ). Total mortality (Z) was estimated by length-converted catch curve at 1.02 and 0.24 yr -1 , fishing mortality (F) at -0.04 and 0.47 yr -1 and natural mortality (M) at 1.06 and 0.71 yr -1 for Lake Qarun and Lake Timsah, respectively. Recruitment was continuous and showed two major pulses in the two lakes.

Populations of the Common European cockle (Cerastoderma edule) often have highly patchy distributions and variable recruitment success. One of the proposed reasons is that high densities of filter feeders and / or bioturbators are thought to reduce the success of larval settlement and post-settlement survival, but the direct causal processes driving these observations are not clearly identified and validated. Through combined field and laboratory experiments, we test the hypothesis that macrofauna cause decreases in post-larval density through feeding and movement activities. The effect of excluding the bioturbating lugworm Arenicola marina and filter-feeding adult cockles on post-larval cockle densities was estimated in separate field experiments at two locations from the time of initial larval settlement in May 2012 to late summer August 2012. Lugworm exclusion led to a significant increase in cockle post-larval densities whereas the opposite was true for adult cockles, where exclusion led to a reduction in C. edule post-larval density. Although clear effects were observed in the field, experiments conducted in the laboratory failed to detect changes in mortality or byssus drifting of post-larvae as a consequence of macrofaunal activity. This study demonstrates that the presence of macrofauna can have both positive and negative effects on post-settlement density of C. edule post-larvae. Thus the density, distribution and identity of macrofauna have significant effects on the density and spatial distribution of C. edule post-larvae during the post-settlement period. These observations have implications for conservation and fishery management of this species.Keywords: Arenicola marina, Cerastoderma edule, interaction, post-larvae, cockle, settlement Highlights  The effect of macrofauna presence on colonisation of cockle post-larvae was tested.  Combined field and laboratory studies were used.
