“…Macrobenthic zonation has the capacity to change much more rapidly than on land, owing to natural changes in population cycles, massive recruitment and seasonal cycles (O'Brien et al 2003). Studies on benthic zonation usually cover a wide range of depths.…”

Short-term study on the early succession stages of fouling communities in the coastal zone of Puck Bay (southern Baltic Sea)The aim of this study was to distinguish the early succession stages of the fouling community in Puck Bay at depths of 3-7 m, to evaluate its biodiversity and to find the point at which the biodiversity of the assemblages achieved similarity. The depth at the study site was 8 m. The investigation lasted from 24 July to 22 September 2008 (61 days) when the colonisation and succession process of fouling communities is most intensive. During this period five sets of samples were collected. The investigations were focused on sessile organisms that established themselves on 105 PVC settlement panels (15 × 15 cm, 0.2 cm thick), 21 panels being deployed at each of five depths - 3, 4, 5, 6 and 7 m. A total of twelve sessile taxa and eight mobile (accompanying) taxa were identified over the course of the experiment. The panels became overgrown with fouling organisms in a characteristic manner - a layer of barnacles became covered with a layer of mussels. This type of community development created a double-layered structure (multi-strata growth). Assemblages reached a thickness of 2 cm as a result of the stratified fouling process. The species diversity was highest on 12 August (the first sampling day) at 7 m depth. Biodiversity differences during the study indicated that communities from all examined depths in Puck Bay became similar after a two-month colonisation period. By the end of the study

Spatiotemporal Variation in Distribution, Size, and Relative Abundance within a Salish Sea Nearshore Forage Fish Community

Forage fish are schooling species commonly occurring in both offshore pelagic and nearshore coastal habitats. Beyond use by some species for spawning, the dynamics of nearshore habitat use are not well understood. The objective of our study was to evaluate the spring–summer dynamics of forage fish occurrence in nearshore habitats of the Strait of Juan de Fuca, Washington. We suspected that habitat changes resulting from removal of two large dams on the Elwha River (2009–2011) may have altered fish presence and abundance. Monthly beach seine sampling in four regions along 40 km of shoreline was conducted from April to September between 2006 and 2019. We caught nearly 600,000 fish, comprising 82 different species. Nine species of forage fish accounted for 81.7% of all fishes caught; most were classified as postlarvae and juveniles based on size. There were spatial differences in the forage fish assemblage between two of our sites but no discernable year effects and no obvious impact of dam removal on forage community composition. Three species represented 78.8% of the catch: Pacific Herring Clupea pallasii, Pacific Sand Lance Ammodytes hexapterus, and Surf Smelt Hypomesus pretiosus. We used a Bayesian generalized linear mixed model to evaluate spatial and temporal variability in the probability of occurrence of these species. Each species exhibited a unique pattern of intra‐annual, interannual, and regional fluctuations. Pacific Herring occurrence progressively increased monthly, Pacific Sand Lance occurrence decreased, and Surf Smelt probability of occurrence peaked in June. Temporal variations in distribution and abundance of these species are likely driven by life history differences and biological requirements. We speculate that specific characteristics of each region, including proximity to spawning areas, spawn timing, extant current patterns, and ecosystem processes, drove variations in distribution between species.

Sandy beaches and their surf zones characterise many of the world's open coastlines. They are important breeding, nursery and feeding areas for many species of fish. Despite the commonness and importance of sandy beach surf zones, the dynamics, space occupancy and diversity patterns of residing fish is in many places poorly understood. The aim of this study was to (1) characterise the fish community structure in 11 simple structured sandy surf zones of the northern Baltic Sea and (2) relate variation in fish abundance and community structure to a set of chosen abiotic variables. Using beach seine, weekly or biweekly sampling was conducted at fixed sites at 10 occasions throughout a summer season. A total of 60,006 fish individuals belonging to 20 species were recorded. Changes in abundance and community structure were mainly driven by the variation of only five species reflecting species‐specific recruitment patterns and different spatial responses to abiotic variables. Dominating groups were Gasterosteidae, Ammodytidae and Gobiidae that together formed 86% of the total adult fish catches. Larval numbers were completely dominated by Gobiidae. Multivariate analyses indicated species‐specific responses to measured environmental variables, most important being a combination of wave exposure, beach slope, bottom roughness, and temperature. The present study shows that changes in fish abundance on simple structured sandy sublittoral beaches in the northern Baltic Sea are large over the course of a breeding season. It also reveals that variation in adult and juvenile fish are driven by a set of abiotic factors that influence on the fish assemblage structure through mainly species‐specific, rather than through generic responses. Unravelling the degree to which the sandy shore fish community vary in the northern Baltic Sea will help in managing coastal environments that are increasingly being threatened by many anthropogenic stressors.
