Attachment Phenomenon of Thick-shelled Squid Eggs on Selected Substrates: A Case in Barru Regency of South Sulawesi, Indonesia

Squids, when spawning, attach their eggs to the preferred substrate to develop well in the selected conditions. Experimental fishing research was conducted by direct observation of squid activities in the spawning area where squid eggs were attached to different substrates. The adult squid would first conduct an inspection and then attach their eggs to the selected substrate. The results showed that squid egg attachment time was conducted in the morning from 06.00 AM to 07.00 AM for 15 minutes at a duration of about 10-30 seconds. The number of egg capsules found in squid houses and various substrates in nature was 1,698 and 1,568 egg capsules. Squid eggs were found at a depth of 1-7 meters, with the most at a depth of 3 meters with 2,718 egg capsules.
