“…Given that juvenile Atlantic horse mackerel show thigmotactic behaviour (Deudero, Merella, Morales‐Nin, Massutí, & Alemany, ; Massutí, Morales‐Nin, & Deudero, ), standard monitoring units for recruitment of fish (SMURFs; Ammann, ; Wilson, Broitman, Caselle, & Wendt, 2008) were used here to monitor nearshore aggregation of this pelagic species. SMURFs can successfully sample ready‐to‐settle fish in the nearshore (Caselle, Kinlan et al., ; Tavernetti, Morgan, & Yu, ; White & Caselle, ). SMURFs were made out of a cylindrical frame of green gardening fence (1.0 × 0.35 m diameter) and filled with plastic fencing to imitate algae, as applied in several recruitment studies in California (Ammann, ; Caselle, Carr et al., ; Wilson, Broitman, Caselle, & Wendt, ).…”

Atlantic horse mackerel (Trachurus trachurus, Linnaeus, 1758) is a highly exploited species, common throughout the North‐East Atlantic. As a pelagic‐neritic fish it typically occurs over the shelf from the surface to 200 m deep on sandy bottoms. Most research has focused on distributions of adults or early life stages (eggs and larvae) of this species in offshore waters and only a few studies have reported the occurrence of early stages near the coast. However, these nearshore environments might be important for the early growth and survival of the Atlantic horse mackerel. In addition, little is known on how environmental processes might affect the early stages of this species. Here, we monitored weekly recruitment of horse mackerel to artificial substrates (SMURFS) deployed near the coast at both the surface and near the bottom, and back‐calculated hatching cohorts. The relationship of both recruitment and hatching patterns with environmental factors was investigated. From a total of 2,515 fish, 2,490 (99%) recruited to surface SMURFS. A GAM and GAMM analysis of the recruitment and hatching patterns, respectively, revealed a strong relationship with the lunar cycle and upwelling. Both recruitment and hatching showed lunar periodicity, with peaks near the new moon and revealed to be influenced negatively by upwelling. This study suggests that the nearshore environment might be an important nursery area for post‐larval and early juvenile Atlantic horse mackerel.

Fish aggregating devices (FAD) are an ancient fishery technique that benefits from the gregarious behavior of many species. They represent alternatives to usual census approach to study fish recruits. Based on this, we test two FAD models built for fish recruitment research, Standard monitoring unit for the recruitment of reef fishes (SMURF) and Artificial Reef Mooring (ARM) moored for the first time close to deep shipwrecks inBrazil Northeastern coast. We compared fish recruits’ abundance sampled by both models at two depths, bottom and mid-water (6 meters from the bottom). SMURFs sampled seven times more fish recruits than ARM with no difference between depth. We discovered that SMURFs mooring tilted 24º in mean with local marine currents. A long-term study with SMURFs tested immersion time influence in recruit’s sampling, and explored recruit’s abundance and standard length at two depth from the bottom. Increasing immersion timefrom 14-28 days did not influence recruit’s abundance. Bottom and Mid-water SMURFs sampled equal recruit’s number and fish sizes were significantly larger at the bottom. FADs, specially SMURFs, showed good tool to sample fish recruits in deeper shipwrecks,however standardization of FAD deployment is indicated to maximize work time and security in unstable sea conditions.

Effect of biological fouling on passive collectors used to estimate fish recruitment

Abstract: Evidence is provided that biofouling of artificial substrata for estimating recruitment of nearshore reef fishes influences recruitment, and it is recommended that investigators consider the effects of fouling when estimating recruitment over space and time.
