Aquaculture Studies moved to a continuous publication model in 2018. Issues were/are being built gradually, with articles being added to the contents list as soon as they were/are ready.  Upon completition of the issue (around the 1st and 15th day of each quarter), we close the issue and any new articles placed in the next issue. Starting with this issue (Volume:23 Issue:1) we will be publishing six issues (January, March, May, July, September and November) per annum. The March issue is scheduled to carry our special issue "Novel Approaches on Feed Ingredients and Additives In Aquaculture" articles.
