This study investigated variations m body condition of brown hoplos (Hoplosternum littorale) refuging in ponds in the Big Cypress region of southern Florida. During the dry season environmental parameters fluctuated, water depth and dissolved oxygen decreased, while temperature and conductivity increased. Standard lengths and wet weights of 675 juvenile brown hoplos were measured from seven populations. Body condition was compared between populations and through time (early vs. late dry...

During the dry season environmental parameters fluctuated, water depth and dissolved oxygen decreased, while temperature and conductivity increased. Standard lengths and wet weights of 675 juvenile brown hoplos were measured from seven populations. Body condition was compared between populations and through time (early vs. late dry season) using length-weight relationship and Fulton's condition factor. The only significant spatia-temporal variations in body condition occurred in the deepest refuges. One population demonstrated an unexpected positive change in body condition, while another (a deep culvert pond) showed negative changes in body condition over time. Smaller fish (≤S65mmSL) found in these deep-water refuges demonstrated the most change in body condition. Almost all populations exhibited isometric growth but the culvert pond population had variable regression slopes (slopes ≠ 3 for both samples).
