<p>Larval of fighting fish (<em>Betta splendens</em> Regan) requires precise live foods for its growth and survival. In this experiment, fish larvae were fed on either <em>Paramecium + Artemia, Paramecium + Artemia + Tubifex, Paramecium + Moina, or Paramecium + Moina + Tubifex</em>. The fish were fed <em>Paramecium</em> from day-2 till day-7 after hatching. There after, the live food was changed according to the treatments till day-28.  Results showed that fish fed on Paramecium + Artemia significantly had the highest total length (12.63 mm) than other treatments (11.86 mm). On the other hand, survival rate of fish had no significant affected by the treatments.</p> <p>Keywords: fighting fish, <em>Betta splendens</em>, <em>Paramecium</em>, <em>Moina</em>, <em>Artemia</em>, <em>Tubifex</em>, larvae</p> <p> </p> <p>ABSTRAK</p> <p>Larva ikan betta (<em>Betta splendens</em> Regan) membutuhkan jenis pakan alami yang tepat bagi kelangsungan hidup dan pertumbuhannya.

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.

The objective of the study was to evaluate effects of 3 different diets and 3 different live food stocking densities on cobia fingerling rearing in composite tanks system in the Ninh Thuan 1st grade Seafood Breeding Center from 6 - 25 days old. The experiment was performed as a 3 × 3 factorial design [live food types: 100% Copepoda (Cop), 100% Nauplius of Artemia (Art), and 50% Copepoda + 50% Artemia; live food stocking densities: 5 - 10 individuals/mL, 10 - 15 individuals/mL, and 15 - 20 individuals/mL]. Each treatment had 5 replicates. After the nursery phase, the results showed that environmental parameters in all treatments were in normal ranges for cobia larvae growth. There was no difference in total length when cobia larvae were fed different feed densities (P < 0.05). The 100% Art live food and the live food density of 15 - 20 individuals/mL gave the highest growth rate, whereas the 100% Cop live food and the live food density of 5 - 10 individuals/mL resulted in the lowest weight of larvae. There was no difference in weight gain when simultaneously changing the types and live food density (P < 0.05). The survival rate of cobia larvae was highest for the 100% Cop live food and the live food density of 15 - 20 individuals/mL and lowest for the 100% Art live food and the live food density of 5 - 10 individuals/mL. However, there was no difference in the survival rate of cobia larvae when simultaneously changing the types and live food density (P < 0.05).

The Relationship

In most species of ducks, only females tend the brood, and they do not defend brood territories. However, in buffleheads (Bucephala albeola), females strongly defend brood territories. I examined factors affecting territory size of broods, and their consequences for growth rate and survival of ducklings. Brood density tended to be higher on ponds with higher food density. Territory size was inversely correlated with both food abundance in the territory and brood density on the pond. The slope of the relationship between territory size and food did not differ significantly from −1, the slope expected if females adjust territory size to maintain a constant food supply. Partial correlation analysis, however, revealed that brood density may be a more important proximate determinant of territory size than food. Growth rates of ducklings were not affected by food density but were depressed at high brood density in one year. Duckling survival increased with food density in the first year but was depressed at high brood density in the next. I suggest that females select a brood territory and that the size of that territory varies according to both food and brood density. This apparently buffers the effects of variation in food and brood density on growth and survival of ducklings.
