Parameter values for zebrafish survival model under two different feed regimes.

<p>Observed (○) and modelled (line) values for parameters <i>a</i> and <i>b</i> in the Beverton-Holt survival model for constant feed (A & C) and individual requirement feed regimes (B & D). Parameter <i>A</i> denotes density-independent mortality and parameter <i>B</i> denotes density-dependent mortality.</p

Dynamic simulation results.

<p>The results of dynamic simulations into the growth and mortality of zebrafish from hatch to 130 dpf maintained under constant feeding conditions. Final population abundance (A) and final population biomass (B) were calculated under full density dependence (dashed red), density dependence in mortality only (dotted blue), density dependence in growth only (dashed green) and no density dependence (solid black).</p

Average number of zebrafish under two different feed regimes.

<p>Average number of individual fish (±s.e) stocked at three different densities (low density - •, mid density -▴, high density - ▪) over 130 dpf under a constant feed regime (A) and an individual requirement feed regime (B).</p

Parameter estimates (and CIs) for the model relating the strength of density dependence on mortality to fish length (Eqn. 5).

Average total length of zebrafish under two different feed regimes.

<p>Average length (±s.e) of zebrafish stocked at three different densities (low density - •, mid density -▴, high density - ▪) over 130 dpf under a constant feed regime (A) and an individual requirement feed regime (B).</p
