In Sally Fine’s current show at the Boston Sculptors Gallery, ‘Catch and Release’ a multitude of sculptural investigations of fish are on view. For this artist, who is predominantly known for her figurative work, this foray into sea life is both an implication of the impact of human beings on the environment and an exploration of her formal artistic concerns. For example, ‘Unschooled,’ refers to the ways in which human behavior has altered fish migration, spawning patterns and whole populations. Another piece offers up ‘Spin offs’ a sculpture of a school of fish caught in a boat propeller blade. The exhibition and accompanying catalog, trace the natural history and evolution of fish, from conservation and sustenance, through overfishing, pollution and fish held in captivity. Likewise, Fine’s use of bronze, aluminum, glass and mixed media, catches these elusive creatures, and evocatively renders their presence as a commentary upon the current state of our ocean.
