The relationship between body condition and diet analysis in a fish is essential for assessing its health, growth, and ecological role. Body condition analysis can be used to explore the influences of any changes in the environment on the condition of the fish, which is a key indicator to assess its wellbeing, reproductive and survival status, and overall fitness of the fish. Diet analysis can provide information on predator-prey relationship can be used to analyse prey preference, trophic interactions, and even seasonal variations of food preferences. The aim of this research is to assess the relationship between diet content, weight and length with body condition, and growth patterns of juvenile fishes, year 0 and year 1 cod. Preliminary results show that there is a variation of prey items in the diet, specifically of Euphausiids, and body condition differs on the location, whether from in-fjord systems or from continental shelf areas. This research would provide insights into the early-life conditions and survival strategies in the northern Icelandic waters, which would help understand growth patterns and provide information on early life history for cod.
