“…In the Gulf of Mexico, there may be a domed relationship between Mississippi River discharge and Gulf menhaden (Brevoortia patronus) production on a decadal scale. Recruitment is negatively affected during years with exceptionally high flows (Govoni, 1997;Vaughan et al, 2007Vaughan et al, , 2011, but adult growth potential is likely enhanced (as observed elsewhere), with greater primary and secondary production driven by riverine nutrient inputs (Lohrenz et al, 1997;Annis et al, 2011). Abundances of the scyphomedusae Aurelia spp.…”

“…On an annual scale, for example, variability in the growth and production potential of young-of-the-year Atlantic menhaden (Brevoortia tyrannus) in Chesapeake Bay is predictably coupled with regional temperature and chlorophyll-a concentrations (Annis et al, 2011). Temperature is also a key predictor of the timing and distribution of scyphomedusae (Chrysaora quinquecirrha) and the production of the comb jelly (Mnemiopsis leidyi) in Chesapeake Bay (Costello et al, 2006;Decker et al, 2007).…”

A majority of the world's largest net-based fisheries target planktivorous forage fish that serve as a critical trophic link between the plankton and upper-level consumers such as large predatory fishes, seabirds, and marine mammals. Because the plankton production that drives forage fish also drives jellyfish production, these taxa often overlap in space, time, and diet in coastal ecosystems. This overlap likely leads to predatory and competitive interactions, as jellyfish are effective predators of fish early life stages and zooplankton. The trophic interplay between these groups is made more complex by the harvest of forage fish, which presumably releases jellyfish from competition and is hypothesized to lead to an increase in their production. To understand the role forage fish and jellyfish play as alternate energy transfer pathways in coastal ecosystems, we explore how functional group productivity is altered in three oceanographically distinct ecosystems when jellyfish are abundant and when fish harvest rates are reduced using ecosystem modeling. We propose that ecosystem-based fishery management approaches to forage fish stocks include the use of jellyfish as an independent, empirical "ecosystem health" indicator. DEDICATION. This paper is dedicated to our beloved friend and colleague, Hermes Mianzan, for his innumerable contributions to fisheries, zooplankton, and gelatinous zooplankton ecology.

“…As a consequence, the ability to develop more accurate predictive models of population growth and decline would be of value to both commercial fisheries and conservation efforts. For example, Annis et al (2011) specifically report that more information regarding size selectivity in Atlantic menhaden would be likely to produce population and growth models more capable of responding to trends in plankton communities. However, without a better understanding of the mechanics of suspension feeding, this remains difficult, especially because of the complex nature of prey selection.…”

Ram suspension-feeding fishes swim with an open mouth to force water through the oral cavity and extract prey items that are too small to be pursued individually. Recent research has indicated that, rather than using a dead-end mechanical sieve, American paddlefish () employ vortical cross-step filtration. In this filtration mechanism, vortical flow that is generated posterior to the branchial arches organizes crossflow filtration processes into a spatial structure across the gill rakers. Despite the known impact of locomotor kinematics on fluid flow around the bodies of swimming fish, the effects of locomotor kinematics on filtration mechanisms in ram suspension feeders are unknown. Potential temporal organization of filtration mechanisms in ram suspension-feeding fish has not been studied previously. We investigated the effects of locomotor kinematics associated with undulatory swimming on intra-oral flow patterns and food particle transport. A mechanized model of the oral cavity was used to simulate the swimming kinematics of suspension-feeding paddlefish. We recorded fluctuations of flow speed and pressure within the model, which occurred at a frequency that corresponded with the frequency of the model's strides. Using the mechanized model in a flow tank seeded with cysts, we also showed that swimming kinematics aided the transport of this simulated food to the posterior margins of the gill slots, although the time scale of this transport is expected to vary with prey parameters such as size and concentration. Dye stream experiments revealed that, although stable vortical flow formed because of flow separation downstream of backward-facing steps in control trials, vortical flow structures in mechanized trials repeatedly formed and shed. These findings suggest strong integration between locomotor and feeding systems in ram suspension-feeding fishes.

“…Suspension-feeding fish that filter food particles as small as 5-3000 μm are key components of food webs and nutrient cycles, with the potential to structure plankton communities (e.g., Vinyard et al, 1988;Schaus et al, 2010;Annis et al, 2011). The diet of a suspension-feeding fish species and the size range of particles ingested should be dependent on the particle capture and retention mechanisms used by the species.…”

The suspension-feeding cichlids Oreochromis aureus (blue tilapia) and Oreochromis esculentus (ngege tilapia) are able to selectively retain small food particles. The gill rakers and microbranchiospines of these species have been assumed to function as filters. However, surgical removal of these oral structures, which also removed associated mucus, did not significantly affect the total number of 11-200 μm particles ingested by the fish. This result supports the hypothesis that the branchial arch surfaces themselves play an important role in crossflow filtration. Both species selectively retained microspheres greater than 50 μm with gill rakers and microbranchiospines intact as well as removed, demonstrating that neither these structures nor mucus are necessary for size selectivity to occur during biological crossflow filtration. After removal of the gill rakers and microbranchiospines, O. esculentus retained significantly more microspheres 51-70 μm in diameter and fewer 91-130 μm microspheres compared to retention with intact structures, but the particle size selectivity of O. aureus was not affected significantly. These results support conclusions from previous computational fluid dynamics simulations indicating that particle size can have marked effects on particle trajectory and retention inside the fish oropharyngeal cavity during crossflow filtration. The substantial inter-individual variability in particle retention by suspension-feeding fish is an unexplored area of research with the potential to increase our understanding of the factors influencing particle retention during biological filtration.
