Data from: The interaction between suction feeding performance and prey escape response determines feeding success in larval fish

The survival of larval marine fishes during early development depends on their ability to capture prey. Most larval fish capture prey by expanding their mouth, generating a suction flow that draws the prey into it. These larvae dwell in a hydrodynamic regime of intermediate Reynolds numbers, shown to impede their ability to capture non-evasive prey. However, the marine environment is characterized by an abundance of evasive prey, such as Copepods. These organisms sense the hydrodynamic disturbance created by approaching predators and perform high-acceleration escape maneuvers. Using a 3D high-speed video system, we characterized the interaction between Sparus aurata larvae and prey from a natural zooplankton assemblage that contained evasive prey, and assessed the factors that determine the outcome of these interactions. 8-33 day post hatching larvae preferentially attacked large prey that was moving prior to the initialization of the strike, however feeding success was lower for larger, more evasive prey. Thus, larvae were challenged in capturing their preferred prey. Larval feeding success increased with increasing Reynolds numbers, but decreased sharply when the prey performed an escape maneuver. The kinematics of successful strikes resulted in a shorter response time but higher hydrodynamic signature available for the prey, suggesting that strike success in our experiments was determined by brevity rather than stealth, i.e. executing a fast strike eliminated a potential escape response by the prey. Our observations of prey selectivity as it happens, reveal that larval performance, rather than preferences, determines their diet during early development.

Data from: Ocean acidification boosts larval fish development but reduces the window of opportunity for successful settlement

Locating appropriate settlement habitat is a crucial step in the life cycle of most benthic marine animals. In marine fish, this step involves the use of multiple senses, including audition, olfaction and vision. To date, most investigations of fish audition focus on the hearing thresholds to various frequencies of sounds without testing an ecological response to such sounds. Identifying responses to biologically relevant sounds at the development stage in which orientation is most relevant is fundamental. We test for the existence of ontogenetic windows of reception to sounds that can act as orientation cues with a focus on vulnerability to alteration by human impacts. Here we show that larvae of a catadromous fish species (barramundi, Lates calcarifer) are attracted towards sounds from settlement habitat during a surprisingly short ontogenetic window of ~3 days. Yet, this auditory preference is reversed in larvae reared under end-of-century levels of elevated CO2, such that larvae are repelled from cues of settlement habitat. These future conditions also reduced the swimming speeds and heightened the anxiety levels of barramundi. Unexpectedly, an acceleration of development and onset of metamorphosis caused by elevated CO2 was not accompanied by the earlier onset of attraction towards habitat sounds. This mismatch between ontogenetic development and the timing of orientation behaviour may reduce the ability of larvae to locate habitat or lead to settlement in unsuitable habitats. The misinterpretation of key orientation cues can have implications for population replenishment, which is only exacerbated when ontogenetic development decouples from the specific behaviours required for location of settlement habitats.

Larval fish abundances off southern California from 1951 to 2016

The 2014-2016 Northeast Pacific Marine Heatwave (MHW) induced the warmest 3-year period on record in the California Current Ecosystem. We tested whether larval fish assemblage structure, phenology and diversity dynamics were comparable to past warming events from 1951-2013. First, we hypothesized, based on past observations of biological effect of warming, that mesopelagic species with southern distributions relative to southern California and Pacific sardine Sardinops sagax (a coastal pelagic species) would increase during the MHW while northern mesopelagics and northern anchovy Engraulis mordax (coastal pelagic) abundances would decline. Similar to past warming, southern mesopelagics increased and northern mesopelagics decreased. Unexpectedly, however, a common southern mesopelagic, Mexican lampfish Triphoturus mexicanus, was approximately three times more abundant than the previous annual high. Further, whereas sardine abundance did not increase, larval anchovy abundance rose to near-record highs in summer 2016. Second, we hypothesized that fishes would spawn earlier during the MHW. Fishes did not spawn in an earlier season within a year, but five of six southern mesopelagic taxa spawned earlier than typical within winter and spring. Third, we predicted that species richness would increase moderately due to an influx of southern and exodus of northern species. Richness, however, was very high in all seasons and the highest ever during the summer as multiple species with primarily southern distributions were recorded spawning for the first time in southern California. The richness of northern species was also unexpectedly high during the MHW. Northern species likely persisted in the study area because in addition to the warm water, pockets of cold water were consistently present. If, as predicted, conditions similar to the MHW become more common as oceans warm, this unique and largely unexpected combination of fishes may reflect future biological conditions.

Data from a mesocosm experiment on responses of larval fish and their prey to warming and browning

This dataset contains data from from a mesocom experiment with larval fish as described in the paper: "Huss, M., van Dorst, R.M., and Gårdmark, A. (2021) Larval fish body growth responses to simultaneous browning and warming" The data comes from a fully factorial experiment of warming and browning in pelagic mesocosms in two adjacent areas in the Baltic Sea archipelago; an artificially heated coastal bay and a natural area with ambient temperatures. To answer the question how simultaneous warming and browning of coastal food webs impact body growth and survival of larval perch. we innoculated the mesocosms, varying in temperature and colour, with larval Eurasian perch (Perca fluviatilis) and zooplankton prey. Browning was simulated by adding coloured substances to the mesocosm bags, whereas the water masses surrounding them in the heated and the natural bay provided the temperature treatment. The main result is that browning decreased body growth and survival of larval perch, whereas warming increased body growth but had no effect on survival. To understand these results, data on daily fish body growth estimates based on otolith microstructure analysis and size composition and abundance of available prey were analysed. The overall conclusion is that larval fish responses to climate change may depend on the relative rate and extent of both warming and browning, as that they may even cancel each other out.

Figure 1. – Data in the STOREFISH database summarized by origin and family, and mapped onto the phylogeny of teleost families from Rabosky et al. (2018). Values in bold are the median number of records across all species in that family (followed by the associated 2.5 and 97.5% quantiles if the number of species in a family is ≥3). Values not in bold are medians for the number of traits for which data are available across all species in that family (followed by quantiles if ≥3 species). Not included in this phylogeny are the families Lotidae (1 species; 69 | 14), Petromyzontidae (11 species; 2, 1, 34 | 2, 1, 9.25), and Thymallidae (2 species; 72 | 13). A high-resolution version of this figure is available from www.storefish.org.
