“…The result obtained with the innovative dredge on the vagile fauna is of major importance: in fact, bycatch minimization is among the most sought-after grails for reducing the environmental impact of fisheries, and in particular in bottom trawling and dredging [37,[45][46][47].…”

This work proposes the experimentation of an innovative hydraulic dredge for clam fishing (Chamelea gallina) in the Adriatic Sea (Italy). This innovative gear aimed at increasing the selectivity of the typical hydraulic dredge used currently, while at the same reducing the impact on benthos through the conception, installation, and experimentation of innovative technological solutions, consisting mainly of a vibrating bottom panel on the dredge and a “warning device” on the dredge mouth. Comparative experiments of the traditional vs. the modified gear, employing two boats fishing in parallel on the northern coast of Abruzzi (Adriatic Sea) and contrasting the catch with both paired comparisons and through modelling, showed that the innovative hydraulic dredge retains fewer undersize clams while yielding similar amounts of commercial product, moreover of higher quality; at the same time, it takes on board less discard, and catches significantly less vagile fauna. In short, the innovative gear is gaining five times over a list of six parameters considered as positive and/or advantageous for the clam fishery. The results allow proposals of potential improvements to clam-fishing instruments to make the selection processes more effective while promoting a lower impacting fishery, which is essential for clam management.

Trap sampling was used to survey the relative abundance of juvenile fish and invertebrates near three habitats including an offbottom oyster cage farm (cage farm), a traditional on-bottom oyster culture area (shell bottom), and a natural cobble and boulder reef (rock reef) in a coastal embayment in Long Island Sound near Milford, Connecticut. Ten traps, deployed on two subsites within each habitat (20/habitat), were allowed to soak for~24 hours, two to three times per week, from June through September 2016. The assemblages of juvenile finfish appeared to be similar on the cage farm and rock reef, while the composition of the invertebrate community was more variable among the three habitats. These preliminary observations suggest that oyster cage farms may provide functional habitat that is populated by structure-oriented finfish communities similar to those that are found on natural rock reefs in Long Island Sound.
