Cercetătorii de la Laboratorul de Ştiinţă şi Tehnologie Militară (DSTL) din Marea Britanie au adaptat un dispozitiv de ghidaj al vaselor printre câmpurile de mine marine pentru a-l folosi la reducerea numărului de delfini şi balene prinse în plasele de pescuit. "Ochii de pisică acustici", de mărimea unei mingi de fotbal, reflectă semnalele sonarelor. Ei sunt folosiţi pentru a marca zone subacvatice curăţate de explozibili.
O versiune mai mică a acestor dispozitive ar putea fi ataşată de plasele de pescuit pentru a reflecta semnalele emise de sonarele balenelor şi delfinilor. Anual, peste 300.000 de mamifere marine mor prinse în plasele pescarilor. (Livia Cimpoeru)
