“…Our findings suggest that it is the species’ traits relative to their reproductive potential and life‐history trajectory that shape the strength of individual body size‐FID relationship. Hence, our analysis stresses the value of focusing on this behavioural trait to manage fish populations (Benevides et al, ; Goetze et al, ).…”

“…However, biomass estimates are often highly variable (McClanahan, Graham, Calnan, & MacNeil, ), which can mask both positive effects of management and lack of effect or compliance. Nevertheless, if FID varies consistently with both individual size and shoal size in different fish species, it has the potential to be a good proxy for the management status or intensity of human disturbance of a focal population (Benevides, Pinto, Nunes, & A. C. C., & Sampaio, C. L. S., ; Goetze et al, ).…”

Here, we present a comprehensive meta-analysis evaluating FID of fish in response to humans, taking advantage of the surge of recent studies on this topic.…”

A meta‐analysis of fish behavioural reaction to underwater human presence

In an increasingly anthropic world, humans have profound impacts on the distribution and behaviour of marine fishes. The increased human presence has modified fishes’ antipredator behavioural responses, and consequently flight decisions, as a function of their changed perceptions of risk. Understanding how fish react to human presence can help identify the most vulnerable functional groups/species and estimate impacts caused by human disturbance. Shoal and body size are known to influence fish flight initiation distance (FID; the distance between the predator and prey when the prey begins to escape); however, few studies attempt to test the moderators of these relationships. Here, we present a comprehensive meta‐analysis evaluating FID of fish in response to human presence. Specifically, we investigated six candidate moderators that could influence the relationship between FID with shoal and body size. Our results showed that individual fish size was strongly and positively correlated with FID and the most important moderator that explained the variance in individual body size‐FID relationship was shoaling behaviour. However, and somehow surprisingly, we detected no significant relationship between shoal size and FID. We discuss how these results can inform the development of fish conservation strategies and ultimately assist in the management of marine protected areas.

“…The effects of spearfishing extraction, such as reductions in density and mean size of targeted fish, are well‐known (Ennis & Aiken, ; Frisch et al, ), however there is less information available on the non‐lethal effects of this fishing method. Consistent spearfishing pressure causes significant changes in fish behaviour, such as increased wariness (Benevides et al, ; Côté et al, ; Goetze et al, ) and flight initiation distance (Benevides et al, ; Gotanda et al, ; Januchowski – Hartley et al, ; Tran et al, ), defined as the distance between the prey and a potential predator when it starts to flee (Gotanda et al, ). Changes in fish escape response have also been noted, with some fish escaping to open water (Guidetti et al, ) or seeking refuge at depth (Côté et al, ; Lindfield et al, ).…”

The grazing behaviour of two Caribbean parrotfish, a fished species, the stoplight parrotfish Sparisoma viride and a non‐fished species, the striped parrotfish Scarus iseri, were studied in the presence (fished site) and absence (marine reserve) of chronic spearfishing activity. Diurnal feeding periodicity did not differ between the sites in either species: roving individuals had significantly higher bite rates in the afternoon, while territorial individuals foraged consistently throughout the day. Mean bite rate varied between sites in both species. Abundance, biomass and bite rates of S. viride were all significantly higher within the reserve, except for roving S. viride which had a higher mean bite rate in the afternoon outside the reserve compared with within it, attributable to maximisation of feeding in the afternoon when fishing risk was lower. Scarus iseri mean abundance and bite rate were greater outside the reserve, potentially because reduction in large territorial herbivores allowed S. iseri to feed more rapidly. By reducing the grazing potential of the remaining S. viride individuals the effect of fishing is greater than would be predicted from biomass changes alone. Less grazing by S. viride would not be compensated for by the increase in grazing by S. iseri because the latter feeds on different algae. Spearfishing of key parrotfish species reduces grazing potential directly by extraction and indirectly by changing behaviour.

“…Although this practice is controversial (Maljkovi c & Côté, 2011) and currently restricted or banned in some marine protected areas (Orams, 2002), it continues to proliferate in several tropical and subtropical regions, attracting more and more tourists to such destinations (Clua et al, 2010;Patroni, Simpson, & Newsome, 2018;Ponzo et al, 2013). The presence of tourists and provisioning of food has been associated with detrimental effects on the physiology (Brookhouse, Bucher, Rose, Kerr, & Gudge, 2013), natural behaviour (Albuquerque et al, 2014;Fitzpatrick, Abrantes, Seymour, & Barnett, 2011), abundance (Foroughirad & Mann, 2013), and population structure (Corcoran et al, 2013) of various fish species, even at sites where operators claim that their business is environmentally responsible (Benevides, Pinto, José de Anchieta, & Sampaio, 2018).…”

1. Tourism in marine environments is growing each year, especially in regions with attractive coastlines. One of the main activities practised by tourists is offering food, normally bread, to fish. This activity can result in negative impacts that are still not fully understood. Such impacts were previously detected among omnivores, but fish at other trophic levels also respond to feeding by humans. 2. The effects of supplementary fish feeding by tourists on the diet of a coral reef predatorial haemulid fish, a common reef fish in many tourist destinations, were analysed. Specimens were sampled from one location in which tourists frequently feed the fish and another in which fish maintain their natural diet, both in a marine protected area. The standard length, total weight, hepatosomatic index, condition factor, starch content, and diet composition of fish from the two locations were compared. 3. Specimens fed by tourists were generally larger than those consuming a natural diet, but weight, hepatosomatic index, and condition factor were not statistically different. Diet composition varied between the two areas, with almost half of the stomach contents from specimens collected in the supplementary feeding area composed of starch. Considering the natural diet of this species, carbohydrate ingestion can interfere with energy accumulation. Additionally, natural prey species were being consumed on a smaller scale. 4. These results shed light on the controversial issue of supplementary fish feeding as a tourist attraction and provide information to help shape effective ecotourism management. In this regard, the offered food volume should be banned in more sensitive environments, reduced in remaining areas and food quality should be controlled to make ecotourism a more sustainable activity globally.
