1983年至1985年，挪威开发了一种用于取代冷鱼叉的季戊四醇手榴弹。在1984-86年狩猎季节的试验中，收集了259头小须鲸的生存时间数据，当时使用了3种不同的原型。大约45%的鲸鱼被瞬间杀死。中位生存期为72 s。记录到的使用戊菊酯手榴弹的瞬时死亡率比使用冷鱼叉的瞬时死亡率高得多。死亡的标准是鳍状肢运动停止，下颌骨松弛，或下沉而没有任何主动运动。有些动物在标准得到控制之前就潜水了。如果中枢神经系统、心脏、肺或主要血管受损，很高比例的动物会立即死亡。在大多数情况下，胸部和中枢神经系统外的命中和爆炸比胸部命中的存活时间更长。生存时间增加鲸鱼的大小和范围的动物没有立即杀死。射击技术、设备的技术和功能可靠性以及狩猎技术都是取得好成绩的关键。更好地训练炮手，改进武器和狩猎设备，更快地重新射击受伤的动物，将减少长期生存的比例。
A penthrite grenade to replace cold harpoons in the Norwegian minke whale hunt was developed in 1983–1985. Data on survival times for 259 minke whales were collected from the trials in the 1984–86 hunting seasons, when 3 different prototypes were used. About 45% of the whales were killed instantaneously. The median survival time was 72 s. A substantially higher percentage of instantaneous deaths was recorded for penthrite grenades than for cold harpoons. The criteria for death were cessation of flipper movement, relaxation of the mandible, or sinking without any active movement. Some animals dived before the criteria could be controlled. If the central nervous system, heart, lungs or main vessels were damaged, a high percentage of the animals died instantaneously. In most cases, hits and detonations outside the thorax and central nervous system resulted in longer survival times than hits in the thorax. Survival time increased with whale size and range for animals not killed instantaneously. Marksmanship, technical and functional reliability of equipment and hunting techniques were all crucial to a good result. Better training of gunners, improved weapons and hunting equipment and more rapid reshooting of wounded animals would reduce the proportion of long survival times.
