“…Luebke and Strawn (1973) calculated K for fish in two ponds receiving heated discharge water from a power plant and noted monthly values from 1.67 to 1.94 from June through November. Those latter values, higher than ones determined from adults in Louisiana, but lower than those for 568 juveniles in Louisiana (K = 1.773 to 2.077, x = 1.969 by Bass and Avault 1975), are somewhat less than some reported here, but variation existed, even among summer values for fish from Mississippi. To obtain the most value from condition coefficients, a continuum of comparative samples should be related (e.g., Ellis and Gowing 1957, Colle and Shireman 1980, Overstreet 1983.…”

Several hundred specimens of the red drum from Mississippi were critically assessed. Regression equations for standard-length (SL) versus total-length differed between males and females and between small and large members of the same sex. A single regression line represented the weight-SL relationship for males with females. For condition coefficients to be helpful, fish had to be grouped at least by sex, season, and length or stage of maturity. By 12 months of age, most fish were about 30 to 32 cm SL and their distribution ranged throughout Mississippi Sound rather than being restricted to inshore bayou and marsh habitats like younger individuals. Juvenile fish tended to have a high hepatosomatic index (HSI) in winter, and adultshadalow one following spawning. The gonosomatic index (GSI) was typically lower than the HSI except for gravid fish in spring and summer. The number of oocytes available for spawning appeared to be much higher than cited in previous reports. The highest calculated fecundity, occurring in a 758 mm SL fish, was 62 million using a volumetric displacement method and 95 million using a gravimetric one. Extrapolated estimates for larger fish were much higher. Resting and yolk-vesicle stage oocytes typically had an irregular shape, an eccentrically located nucleus, and an abundance of highly basophilic substance in the ooplasm. Throughout a seasonal histological examination, both gonads contained, often in an abundance, Periodic-acid-Schiff-positive granular leukocytes. Spawning took place in late September and October one year, but apparently has occurred over longer periods when conditions of temperature and photoperiod were appropriate. No tagged, 1-year-old fish were returned from farther than 33 km from the point of release.

“…By September, some came from near the barrier islands as well as from the inshore marsh habitats. Bass and Avault (1975) showed fish to average 325 mm TL at the end of the first year, 540 mmat the second,and 760 mm at the third, which are larger values than most authors report. Etzold and Christmas (1979) …”

Contents from numerous juvenile drum have also been recorded from Texas by Miles (1950) and from Louisiana by Bass and Avault (1975).

Examined digestive tracts of the red drum in Mississippi Sound contained mostly decapod crustaceans.Crustaceans accounted for 34 of 59 encountered taxa, more than reported from any other region. Nevertheless, the general diet for 104 fish with food contents out of the 107 examined is similar to that reported for red drum in several other studies from other areas. In addition to crustaceans, fishes followed by polychaetes occurred as the most important items (in 99, 43, and 15% of the drum with food, respectively). Blue crabs occurred in even more drum than the frequently encountered penaeid shrimps. Other commercial species were negligible in the diet. Sixteen large drum from Georgia beaches were also examined; unlike those from Mississippi, many of these contained echinoderms, but not polychaetes or penaeids. We suggest that the red drum's migrations may be regulated by optimal abundance of specific types of dietary organisms.

“…Spawning red drum can be found in both open and nearshore waters in the Gulf of Mexico and tend to spawn near shorelines during late summer and fall (Tables 9.27 and 9.28). There is little evidence of seasonal migration of red drum, and they have been found in rivers and tidal creeks during Bass and Avault (1975) Common predators of juveniles Amberjack, large piscivorous fishes, sharks, and birds; typically not normal part of diet of any common estuarine predator Overstreet (1983), Porch (2000) Common predators of adults Sharks; not a normal part of the diet of any common estuarine predator the winter. Tides and water temperatures influence daily movement from shallow to deepwaters.…”
