“…Until now, feeding, growth and survival of cephalopods are comparable to fish larvae being weaned from natural to prepared diets (Dabrowski et al 1978;Lindberg and Doroshov 1986). This inability to grow cephalopods on an inexpensive and storable prepared diet has inhibited cephalopod mariculture on a commercial basis (O'Dor and Wells 1987;Lee et al 1991).…”

The effects of artificial diets on growth and body condition of adult cuttlefish, Sepia officinalis were tested in two experiments. Supplemented prepared diets (fish myofibrillar protein concentrate) were fed during a 30-day and a 21-day experiments. Growth, feeding rate and food conversion of group-reared cuttlefish were analyzed. The first of these experiments tested four artificial diets, made with increasing levels of lysine, on adult cuttlefish. According to the chemical analysis, diets 1-3 had limiting concentrations of lysine and other essential amino acids (compared to mantle composition of the cuttlefish), while diet 4 was the only one where almost all essential amino acids were present in concentrations similar or higher than the ones present in cuttlefish mantle. A second experiment was conducted by isolating 16 adult cuttlefish individually, and feeding them the same four artificial diets, in order to obtain individual data. During Experiment 1, only the diet with the best chemical score (diet 4) produced growth (p < 0.05), with a mean instantaneous growth rate (MIGR) of 0.30% wet body weight (BW) d À1 . Similarly, individually reared cuttlefish fed diet 4 produced the highest IGR's (0.26, 0.38 and 0.48% BW d À1 ) and grew larger (p < 0.01). Comparison of cuttlefish fed the artificial diets vs. thawed shrimp and unfed cuttlefish indicated that cuttlefish fed the artificial diets were in an intermediate state. Growth rates obtained with the artificial diets (<0.4% BW d À1 ) were considerably lower compared to natural prey, live or frozen, reported by other authors.

“…Our results clearly indicate that survival of lake sturgeon fed black fly larvae is comparable with that of individuals fed using the traditional method; however, it must be noted that fish that were switched to black fly larvae after a 3-d transition period had a significantly higher survival rate than those switched to bloodworms over the same period of time ( Figure 2). Food preference behavior in larval and juvenile sturgeon is well documented (Lindberg and Doroshov 1986;Bardi et al 1998;Soriguer et al 2002) and is probably associated with preferential smell, palatability, shape, and texture (Bardi et al 1998). Chopped bloodworms may lack the suitable properties to encourage immediate feeding by larval sturgeon, and this may explain why continuous feeding and transition periods are required to obtain reasonable survival rates.…”

Live and frozen black fly larvae (Diptera: Simuliidae) were incorporated into the diets of larval lake sturgeon Acipenser fulvescens in 2002 and 2005 for a 6‐week period to determine whether fish would accept this invertebrate diet more readily than conventional bloodworm (Diptera: Chironomidae) diets. In 2002, daily feedings of live black fly larvae within an 8‐h period resulted in a mean survival rate of 37%. Adjusting the diet regime in 2005 (i.e., initial diet of brine shrimp Artemia spp., two daily feedings within a 14‐h period, and diet transition periods of 3, 5, and 7 d) resulted in overall mean survival rates greater than 80%. Survival of lake sturgeon transitioned to black fly larvae was significantly better than that of control groups transitioned to bloodworms over 3 d and statistically similar to that of bloodworm‐fed groups transitioned over 5 and 7 d. Fewer feedings and lower daily rations of black fly larvae in comparison with bloodworms did not result in differences between the final mean mass of fish in 2005. We conclude that frozen black fly larvae can reduce the effort required to transition lake sturgeon from an initial diet of brine shrimp without compromising current survival and growth standards achieved with bloodworm diets.

“…To avoid potential habituation effects, cultured food organisms (rotifers or Artemia sp. nauplii) were never used as experimental prey items (Checkley 1982, Lindberg & Doroshov 1986, Mills et al 1987, Connaughton & Epifanio 1993. Fishes used in any given experiment were usually from the same brood or nest.…”

Selective feeding behavior of larval naked gobies Gobiosoma bosc and blennies Chasmodes bosquianus and Hypsoblennius hentzi:preferences for bivalve veligers

Naked gobies Gobiosoma bosc, striped blennies Chasmodes bosquianus, and feather blennies Hypsoblennius hentzi provide important intermediate links within the trophic structure of estuarine oyster reef communities. Predator-prey interactions between planktonic larvae of these fishes and larval eastern oysters Crassostrea r~irginica may influence recruitment success within oyster reef communities. These 3 species of oyster reef fish larvae were cultured from wild nests and used in multifactorial laboratory feeding experiments with larval oysters or hard clams Adercenaria mercenaria as well as wild plankton as prey items to determine the effects of predator age, predator concentration, and prey type on feeding selectivity of these fishes. Predator age significantly influenced feeding behavior of naked gobies and feather blennies. Predator concentration did not significantly effect feeding behavior for any of the 3 fish species. Prey type significantly affected feeding behavior of feather blennies and naked gobies. Naked gobies consumed bivalve veligers preferentially at all veliger concentrations. Feather blennies consumed veligers preferentially at concentrations as low as 12 % of the available prey field. Striped blennies were less specialized in their feeding patterns but still consumed bivalve veligers preferentially at prey field concentrations as low as 11 % veligers.
