“…In most cases, that boundary may operationally be defined by topographic features, which should be validated by spatially different water current patterns (e.g., Figure ). For decapodids of larval export‐type decapods, mainly, three types of tidal sphere with a distinct boundary have been studied: (a) estuary of a varying flow‐path length, with a narrow inlet to the coastal ocean (Moser & Macintosh, ; Ogburn et al, ; Queiroga et al, ; Wooldridge & Loubser, ); the lower part of a tributary to the main body of a large estuary also belongs to this type (Olmi III, ; Qin, Sheng, Chu, Wang, & Wu, ), (b) lower part of a large estuary to the coastal ocean, with an absolutely wide mouth (McConaugha, ; Tilburg, Dittel, & Epifanio, ), and (c) open coastal embayment of varying dimensions, with a wide mouth relative to its distance to the shore (Flores et al, ; Olaguer‐Feliú et al, ; present study). These inlets and mouths can be regarded as the above‐mentioned “boundary”.…”

Semilunar postlarval settlement periodicity ensuing from semilunar larval release cycle in the Nihonotrypaea harmandi (Crustacea, Decapoda, Axiidea, Callianassidae) population on an intertidal sandflat in an open marine coastal embayment

Many decapod crustaceans in marine intertidal habitats release larvae toward coastal oceans, from which postlarvae (decapodids: settling‐stage larvae) return home. Decapodid settlement processes are poorly understood. Previous studies showed that in Kyushu, Japan, the callianassid shrimp population on an intertidal sandflat of an open bay joining the coastal ocean near a large estuary released eight batches of larvae basically in a semilunar cycle from June through October and that decapodids performed diel vertical migration, occurring in the water column nocturnally. We conducted (a) frequent sampling for population density and size‐composition on the sandflat through one reproductive season, (b) planktonic and benthic sampling for decapodids around the bay mouth, and (c) current meter deployment at three points across the bay mouth for tidal harmonic analysis. On the sandflat, six batches of newly‐settled decapodids (settlers) occurred in a semilunar periodicity until October, with peaks occurring 0–3 days before syzygy dates except for the first one. For larval Batches 1–4, buoyancy‐driven shoreward subsurface currents during July to mid‐October would transport some pre‐decapodid‐stage larvae (zoeae) toward the bay. The absence of expected settler Batches 7–8 would be due to the converse subsurface currents caused by water‐column mixing and seasonal winds after mid‐October, carrying zoeae offshore. Once in the bay, phasing of night and nighttime‐averaged shoreward tidal current explained the settlement pattern for Batches 1–4. For Batches 5–6 occurring in mid‐September to mid‐October, water currents generated by seasonal wind and tidal forcings may have caused peak settlement after the time expected from tidally‐driven decapodid transport.

“…Por otra parte, se ha considerado que las mareas son los principales mecanismos transportadores de plancton en las zonas costeras (Borgianini et al 2012), lo cual explicaría la mayor abundancia de larvas durante meses correspondientes a boca abierta. Esto coincide con lo expuesto por Qin et al (2015), quienes señalan que, durante la estación lluviosa, se presenta el reclutamiento de larvas de crustáceos.…”

The dominant zooplankton of the La Mancha lagoon, Veracruz, Mexico, was analyzed with the objective of evaluating its seasonal and diel variability, as well as the influence of the main environmental variables on this variability. From May 2012 to April 2013, every month a 24-h cycle was completed, taking samples every 4 h, at the mouth of the lagoon. Simultaneously with zooplankton sampling, in situ environmental parameters such as temperature, dissolved oxygen, salinity, chlorophyll a and number of phytoplankton cells were recorded. We collected 54 taxa (mainly holoplankton) and 10 of them were considered dominant (total abundance > 0.5%). The zooplankton community was dominated mainly by two species of copepods (Acartia tonsa and Pseudodiaptomus pelagicus), as well as zoea larvae of brachyura (~85%). At seasonal level, the total abundance of zooplankton showed significant pulses throughout the year, one in February-March dominated by copepods and another in September-October, dominated by decapod larvae. On a diel scale, although total zooplankton abundance was significantly higher at night, only P. pelagicus, amphipods, megalopae, and other decapod larvae showed significant differences at this level. According to a Canonical Correspondence Analysis, the mouth stage (open/close), the number of cyanophytes and precipitation were the most important environmental factors in determining the abundance of the dominant zooplankton.

“…Estuarine rocky reefs are present in many estuaries, particularly along the littoral fringes where they support valuable sheries (Pease 1999). Research on estuarine habitat has typically focused on saltmarsh, mangroves and seagrass habitats (Hindell 2006 There is often high productivity and tidal-driven supply of zooplankton in estuaries (David et al 2005;Qin et al 2015), which may support signi cant sh biomass (Kennish 2019) with tidal currents transporting zooplankton past estuarine rocky reefs, as occurs on coastal reefs (Champion et al 2015). However, it is unclear how reliant estuarine sh assemblages are on zooplankton compared to coastal reefs, and whether macrophytes or detritus are more important energy sources than for the open coast.…”

The trophic basis of fish assemblages in temperate estuarine and coastal ecosystems

More than half of the sh biomass of coastal rocky reefs depends on zooplankton; however, the trophic basis of estuarine sh assemblages remains unknown. We quanti ed the trophic basis (i.e. basal energy sources) of sh community biomass inhabiting three habitat types (seagrass, natural reef and arti cial reef) in two estuaries, and at two coastal rocky reef sites. Estuarine sh assemblages were surveyed with Baited Remote Underwater Video (BRUVs). Species abundance, richness and biomass of sh were classi ed into 9 functional feeding groups (3 elasmobranch and 6 teleost). Comparable metrics for coastal sh assemblages were obtained from published surveys using BRUV, remote underwater video and visual census survey methods. Using the functional feeding group biomass and the group-speci c diet composition, the breakdown of energy sources was calculated using a food web analysis. Estuarine reef habitats had different species and different functional feeding group composition than seagrass habitat. The majority of sh biomass in the seagrass habitat was supported by detritus (51% at one estuary) or macrophytes (58% at the other estuary). In contrast, zooplankton supported most sh biomass (45-59%) at the coastal reef locations, and in reef habitat in one estuary (35-43%), but not the other estuary (33-34%). The trophic basis of estuarine and coastal sh assemblages reveals their potential response to urbanisation including changes to habitat, nutrient supply and current ow.
