Small fish eat smaller fish: a model of interaction strength in early life stages of two tuna species
<p>Fish larvae are rarely a major driver of fish mortality, but tunas can produce large batches of larvae that rapidly develop the capacity to kill other fish. We combine a model for the killing potential from Atlantic bluefin tuna (BFT) larvae on larval albacore (ALB) with field observations at a major spawning ground. Both species spawn from June to August, but BFT has a narrow spawning peak at the beginning of the season that results in priority effects. Our model shows that, following a recent stock recovery, BFT larvae have increased their killing pressure, leaving areas of up to 1000km<sup>2</sup> with <1% chance of ALB daily survival. Such increase in killing pressure suggests larval ALB has reduced chances to survive, yet in large areas with few BFT other drivers of early survival prevail over BFT predation. This shows that strong predatory interactions can occur during larval stages in some fishes.</p>
Figure 4 in Invasive Carassius spp. in the Tiber River basin (Umbria, Central Italy): population status and possible interactions with native fish species
Figure 4. – Canonical Correspondence Analysis: plot of the densities of native and non-native species. The eigenvalues of axes 1 and 2 were 0.249 and 0.046, respectively. The first two axes explained 73.70% of the total variance.

Figure 3. – Canonical Correspondence Analysis plot of the environmental variables. The arrows represent the vectors of the environmental variables. The length of the arrow is proportional to the importance of each variable: a long arrow indicates large spatial changes closely correlated with the ordination axes.
