Abstract The aim of the study was to determine the influence of the size and form of Artemia sp. feed on the rearing indices of Atlantic sturgeon larvae. In the experiment, the nauplius sizes used were 480 µm (group AD), 430 µm (group AM), and 430 µm frozen nauplii (group AI). After three weeks of rearing, the sturgeon from group AD had the highest mean body weight of 0.131 g that was statistically significantly different from groups AM (0.071 g) and AI (0.033 g). The longest total length was noted in group AD (2.8 cm) and was statistically different from the others (P ≤ 0.05). Specific growth rate in groups AD and AM was 14.7 and 11.8% d−1, respectively, and these values differed statistically from those in group AI at 7.8% d−1. The highest survival rate was recorded in group AD at 60.6%, while the lowest was noted in group AI at 15.6%, and the differences between these two groups were statistically significant. The results of the experiment indicated that a feed of live 480 µm Artemia sp. nauplius significantly accelerated the growth rates and increased the survival rates of Atlantic sturgeon larvae.

Hasil penelitian ini dapat dijadikan informasi dasar untuk melakukan pendederan ikan betutu secara terkontrol.Sand goby, Oxyeleotris marmorata is a potential fish species for aquaculture in Indonesia. However, the growth performance and survival rate of the fish seed are still low. Such challenges could be solved through the optimization of stocking density of the fish. The research objective was to determine the optimal stocking density to produce high growth and survival rate, as well as the best physiological response. The ponds used in this experiment were 2 m x 1 m x 1 m in size (water volume: 1 m3). The stocking density treatments were 50, 100, and 150 individual/m3. The initial fish length average was 4.24 ± 0.58 cm, with the initial body weight average of 2.74 ± 0.45 g. During 60 days of rearing period, the fish were fed with Tubifex sp. ad libitum. The results showed that the survival rates on different stocking densities were not significantly different. The highest specific growth on length (1.50 ± 0.37%/day) and body weight total (1.95 ± 0.32%/day) and the most stable physiological response related to its hematological parameters were achieved by seed stocked at 50 individuals/m3. The best biomass total was achieved by seed stocked at 150 individuals/m3. The result of this study could be applied as basic information to culture sand goby in a controlled environment.

No well-defined changes in growth and survival rates of native brook trout (Salvelinus fontinalis) were detected during a 13-yr period when non-trout species were removed from a small Adirondack Mountain stream using fixed traps located throughout the system. The catch of non-trout species was about 124,000 weighing 2000 kg, and of trout, 13,000, weighing 500 kg. Slow growth characterized the population through this time, with mean lengths of 13.2, 17.3, and 21.3 cm at ages I+, II+, and III+, respectively. The weighted annual survival rate for ages II–V was 18%, with most deaths due to natural causes. The most striking observation was virtual cessation of movement of both trout and non-trout species after 7 yr, suggesting that the removal program had an effect on population behavior, even if it was not reflected in an improvement in trout growth.
