Web9 May 2024 · INTRODUCTION. Shoaling is the formation of social groupings in fish, and, for adults of many species, shoaling is the norm (Pitcher and Parrish 1993).Shoaling can provide several benefits including enhanced detection and evasion of predators (e.g., Magurran et al. 1985; Godin 1986; Magurran and Pitcher 1987), dilution of predation risk … WebWave shoaling is the process when surface waves move towards shallow water, such as a beach, they slow down, their wave height increases and the distance between waves decreases. This behavior is called shoaling, and the waves are said to shoal.
