Hazrat Saad al-Jari, the freed slave of Sayyiduna Umar bin Khattab (may Allah be pleased with him), said: I asked Sayyiduna Abdullah bin Umar (may Allah be pleased with them): What about those fish that are killed by other fish or die due to cold? He said: Their consumption is permissible. Then I asked Sayyiduna Abdullah bin Amr bin al-As (may Allah be pleased with him), and he said the same.
