Seahorse (Hippocampus kuda,Signathidae) ponies were reared for 15 days at the laboratory of Marine Biological Research Station, Ratnagiri (India) using three types of live food viz Artemia nauplii, rotifers (Branchionus plicatilis) and a combination of both. The experiment was conducted in all glass aquaria (0.30 m x 0.30 m x 0.30 m). Seahorse ponies (10 + 0.27 mm) were stocked at 2 L-1 and fed with nutritional live food ad libitum. After 15 days of rearing, the ponies were counted and their individual lengths and weights were recorded. Significantly higher (P< 0.05) weight gain percentage (128.92 + 1.27%) of seahorse ponies, length gain percentage (57.4 + 0.82%), SGR percentage per day (5.53 + 0.04% day–1) and survival percentage (100%) of seahorse ponies were observed in the combination of Artemia nauplii and rotifers as food compared with Artemia nauplii or rotifer alone. Rotifers as live food resulted in poor growth and survival of seahorse ponies under this experimental condition.

Hippocampus Kuda

Breeding of laboratory-reared 21 pairs of broodstock Hippocampus kuda (Bleeker 1852) and rearing of their young ones indicated that 262.00 ± 59.00 offsprings were released during each spawning. A newly born seahorse was (mean ± SE) 7.83 ± 0.11 mm in length with a weight of 1.17 ± 0.009 mg. It could attain a mean length of 31.14 ± 0.66 mm with a mean weight of 16.13 ± 0.60 mg in 30 days when fed ad libitum with Artemia nauplii. The mean survival per brood cycle was enhanced to 65.22 ± 1.87% from almost less than 1.0% by improving the rearing conditions.

Four microencapsulated diets were evaluated with respect to the growth and survival of tropical gar Atractosteus tropicus larvae. The treatments consisted of four experimental diets and one control diet 1) fish meal, 2) a combination of pork and poultry meals, 3) Nannochloropsis gaditana meal, 4) enzyme preparation and the control treatment 5) Artemia nauplii. The evaluation indicated that the larvae fed the Artemia nauplii obtained the greatest growth and survival (3.93 cm, 0.19 g y 82 % respectively), which justifies a correct culture system operation. While larvae fed microencapsulated diets best values in survival were observed with diets Nannochloropsis gaditana and enzyme preparation (20.0 and 19.2 %). Our results showed that microencapsulated could be used to feed A. tropicus in feasibly form. However, more information concerning to optimize the design and manufacturing are required to improve the growth and survival of organisms.

ABSTRACT: The feeding frequencies on pacamã Lophiosilurus alexandri larviculture were evaluated. In the first phase, 10 days of active feeding, larvae with nine days post hatching (13.5 ± 0.7 mm) were stocked at density of 10 larvae L-1 in 5-L tanks each. The experimental treatments were: F2T (feeding 8h00 and 17h00); F2M (feeding 8h00 and 12h30); F3 (feeding 8h00, 12h30 and 17h00); and F4 (feeding 8h00, 11h00, 14h00 and 17h00). During this phase Artemia nauplii were used as food. In the second phase, during 15 days, juveniles were restocked in 20-L tanks at density of 2.2 juveniles L-1, and kept the same feeding frequencies of the first phase. Commercial dry diet containing 40% crude protein was used as food. No effect of feeding frequency on growth and survival, during both phases, was observed. However, survival decreases from the first to the second phase, showing the importance of the type of food. During the L. alexandri larviculture should be recommended twice a day feeding frequency.

Preliminary Study

This experiment was conducted to investigate the influence of vitamin C on growth and survival rate of freshwater prawn larvae. The treatment dosages of vitamin C were 0.0, and 0.75 mg/L. Each treatment was in triplicates and arranged in a complete randomized design. Vitamin C was given to the larval rearing media every three days. Larvae were cultured in six conical fibreglass tanks of 50 L volume installed in a fibreglass tank (2 m x 0.8 m x 0.8 m) filled with water for temperature stabilizer. Each conical tank was stocked with 6,500 larvae (nauplii). Artemia nauplii were given on D3 and egg custard as artificial feed on D9. Larval rearing was done for 25 days in constant temperature (29oC–31oC) using automatic heater. Statistical analysis showed that metamorphosis speed of larvae was significantly affected by adding of vitamin C (P<0.05), but survival rate was similar (P>0.05). Addition of vitamin C also resulted in a better growth of freshwater prawn larvae.

Abstract Newly hatched Coregonus maraena (Bloch) larvae reared in aquaria were observed during two trials in 2014 and 2015 for 42 and 34 days after hatching in order to determine the on-feeding effects of different feeding strategies on growth and survival. Feeds of commercial dry feed, live Artemia nauplii, frozen rotifers, and mixtures of these were compared. Larval whitefish were fed brine shrimp for up to 13 days beginning 4 days post hatch (dph). Whitefish larvae fed live Artemia for 8-9 h per day over a period of 10-12 days grew considerably larger (mean value of final total length (TL) 27.3-33.0 mm)) and were heavier (mean value of final body weight (BW) 112-165 mg)) than those fed dry feed, frozen rotifers, or Artemia for 3-6 days (TL= 22.6-30.2 mm; BW= 50-102 mg). The growth of larvae fed for 24 h solely on dry food was comparable (BW= 101 mg, TL= 26.6 mm) at 42 dph. Survival differed among groups (31-63%) and was highest for larvae fed dry food exclusively. Our results can improve the first feeding of Maraena whitefish larvae in small-scale fish farms.
