Abstract

The need for carp (Cyprinus carpio) from year to year continues to increase with the increase in population. Consumer demand for fish consumption has experienced a shift, from fresh (frozen) fish to live fish. The obstacles often faced by cultivators are death before the fish arrive at their destination, the cause of fish death is due to stress and physical damage due to mishandling. To avoid the high mortality rate of carp during the transportation process, fish entrepreneurs have begun to develop a dry transportation system, namely a system of transporting live fish using non-water transportation media. In the transportation of live fish without water media, the fish are made in a state of calm or stunning. Anesthesia can be done by giving an anesthetic in which the fish becomes unconscious during the transportation process. The advantage of stunning this fish is that it makes it easier to carry out the transportation process without water media, makes the fish not move much during the transportation process and minimizes the risk of fish being injured so as to allow a longer transportation time. One of the natural ingredients that can be used for anesthesia is tobacco (Nicotiana tabacum). The purpose of this study was to determine the effect of anesthetic tobacco extract (N. tobacum) on the hematological condition of carp (C. carpio) by dry transportation method. The treatments tested were soaking tobacco extract as fish anesthetic before transportation with different concentrations, namely, in treatment 1 (P1) without soaking tobacco extract, treatment 2 (P2) soaking tobacco extract 1 ml, treatment 3 (P3) soaking tobacco extract 2 ml, treatment (P4), soaking extract 3 ml. The results of this study that the use of tobacco leaf extract as an anesthetic in the dry transportation system causes hematological levels to increase and decrease but are still in normal levels, the best dose of tobacco extract is 1ml/L with a stunning speed of 917 minutes, recovery time is 239 minutes and has an SR value of 76%.

Abstract

This study aims to analyze the effect of different cross-sectional areas of recirculation systems on water quality in tilapia (Oreochromis niloticus) rearing. The method used is an experimental method with a completely randomized design (CRD), 4 treatments and 3 replications each. The treatments are P0 (conventional), P1 (2 cross-sectional units with an area of ​​1,087 cm2), P2 (4 section units with an area of ​​2,174 cm2), P3 (6 section units with an area of ​​3,261 cm2). Each treatment used the same filter, namely cotton, zeolite, pumice stone, and bio balls. The results of the research the highest absolute weight growth was obtained in the P3 treatment with an average value of 4.56 g and followed respectively P2 4.38 g, P2 3.03, P0 2.59 g. The highest absolute length growth rate was obtained in treatment P3 2.71 cm, P2 of 2.54 cm, P1 of 1.87 cm, and the lowest absolute length was found in treatment P0 of 1.62 cm. The highest feed conversion value was at P0 at 3.91, followed by P1 at 2.84, P2 at 2.06, and the lowest at P3 at 1.94. The highest survival value was P3 of 85.00, P2 r 83.33, P1 73.33 and the lowest was P0 of 55.00. The highest diversity coefficient value was obtained in treatment P0 of 17.58, followed respectively by treatment P1 of 16.05, P2 of 12.91 and the lowest coefficient of diversity found in treatment P3 of 12.69. The conclusion of this study is the use of different recirculation cross-sectional areas has a significant effect on absolute weight growth, absolute length growth, feed conversion ratio, survival, and water quality. The recirculation cross-sectional area in P3 treatment with a cross-sectional area of 3.261 cm2 gave good results for the survival of tilapia.

Abstract

Sargassum sp. is seaweed from the group of brown algae belonging to the Phaecophyceae class that can be found in Indonesian. Sargassum sp. contains polysaccharides in the form of alginate which can be used as raw materials and additives in the food, drug, and cosmetic industries. The aim of this study was to analyze the growth of Sargassum sp. which are cultivated with different seed weights on the floating rafts. The research was conducted from November 2020 to March 2021 in Ekas Bay, East Lombok, West Nusa Tenggara. The research method used is an experimental method using a completely randomized design (CRD) consisting of five treatments with four replications. The treatments were differences in the weight of the initial seeds used, namely treatment A (25 g), B (50 g), C (100 g), D (150 g), and E (200 g). Sargassum sp. Cultivation was carried out for a month. The results were the highest absolute weight was in treatment E with 550 g and the lowest occurred in A with 262.5 g. The highest specific growth was in treatment A with 8.13%/day and the lowest was in E with 4.4%/day. This study concluded that different seedling weights had a significant effect on the growth of Sargassum sp. cultivated using the floating raft method
