The selected or preferred temperatures of the carp were determined for six acclimation temperatures. At 10 °C., 15 °C., 20 °C., 25 °C., 30 °C., and 35 °C. acclimation the selected temperatures were 17 °C., 25 °C., 27 °C., 31 °C., 31 °C., and 32 °C. respectively. The final preferendum of carp was found to be 32 °C.

Preferred temperatures of underyearling rainbow trout (Salmo gairdneri) were determined in both vertical and horizontal temperature gradients. No statistically significant difference was found between the preferred temperatures by the two different methods. This suggests that the nature of the gradient plays a lesser role than generally believed in laboratory investigations of temperature preference.

Abstract. Andayani S, Dadiono MS, Elwira WT, Setyawan FH. 2020. Potency of aloe extract as immunostimulant for carp (Cyprinus carpio) against Aeromonas salmonicida. Biodiversitas 21: 860-864. The objective of the study was to be able to know the cellular and humoral non-specific immune response to Aeromonas salmonicida after aloe extract administration. This study employed Complete Randomized Design with 3 treatments and 3 replications, control treatment (K), A =2 ppm of aloe extract application in the media, B = 16 ppm of aloe extract in the media, and C = 30 ppm of aloe extract in the media. The extract was given through one-hour soaking at day 0 and day 7, and then challenge-tested to 107 cells.ml-1 of A. salmonicida into the media for one day. Results showed that administration of aloe extract could raise plasma protein levels from 443.0 to 662.0 mg.Kg-1 antibody from 1.2576 to 3.3974, and phagocytic activity from 30.61% to 45.94%. Similarly, the differential value of leucocyte (lymphocyte from 58.6% to 73.70%, neutrophils from 6.09 to 8%, and monocyte from 5.70% to 7.72%). As conclusion, aloe extract at the dose of 2 ppm could raise the cellular and humoral non-specific immune. Therefore, the use of aloe extract as immunostimulant at the dose of 2 ppm applied through immersion could also apply other methods, such as oral and injection.

Common carp (Cyprinus carpio) is one of the most widely cultured fish species in the world. It is predominantly cultivated in the Balkans in the semiintensive system that is based on the utilization of natural food from the fish pond and supplemental feed (cereals, pelleted and extruded feed). Currently, an intensified type of semi-intensive production is starting to be more present in Serbia, where cereals, as the most common supplemental feed, are replaced by concentrated feed that fill in the lack of proteins from carps? natural food in periods of its decreased production. The nutritional requirements for growth, reproduction and normal physiological functions of fish are similar to other animals, but generally fish need more proteins in their diet. Due to this, the efficiency in the use and utilization of proteins is more significant for fish than for other animals. The selection of supplemental feed in semi-intensive system of fish culture depends on the natural potential of the fish pond, culturing period, fish category, price and quality of feed.
