Triploid Fish

<p>Seurukan fish (<em>Osteochilus vittatus</em>) has many advantages, besides the fish also has disadvantages which are the slow growth, so the temperature shock of triploidization technique was expected to solve the problem.   The objective of the present study was to obtain an effective temperature to increase of triploidization success of <em>seurukan</em> fish (<em>Osteochilus vittatus</em>). The experimental method and completely randomized design model were used in this study. Five levels of temperature shocks at three replicates were tasted: 4℃ (cold), 6℃ (cold), 28℃ (normal), 35℃ (heat) and 37℃ (heat). The sperms and eggs were fertilized in the plastic jar then a total 100 of fertilized eggs (zygotes) were taken randomly 3 minutes after fertilization and soaked in respective temperature for 90 seconds, and then incubated in incubation jars at the water temperature of 28-29℃. The results showed that the temperature shock gave the significant effect on the hatching and the success of triploidization success (P˂0.05), but did not give the significant effect the fertility and survival rates (P&gt;0.05). The triploid fish can be achieved using cold and heat shock, but the higher triploid fish was recorded at 37℃ was the best temperature recommended for triploidization of <em>Seurukan</em> fish.</p>

The purpose of this research is to determine the optimal dose of the addition of red spinach powder to artificial feed on the brightness of clown loach. This research was conducted at Aquaculture Laboratory Building 4 Faculty of Fisheries and Marine Sciences of Universitas Padjadjaran from April to May 2020. This research method is experimental with a Completely Randomized Design consisting of four treatments and three replications. The red spinach powder addition treatment used 0%, 2%, 4%, and 6% of the feed amount. The parameters observed are color value as primary data by using Toca Color Finder, while the growth, survival rate, and water quality as support data. Color assessment results were analyzed using the Kruskal-Wallis test, if there were significant differences, Z test would be performed. Growth data and survival rates were analyzed using Analysis of Variance (ANOVA). Because the F test results were not significantly different, the Duncan test was not carried out. The results showed that the addition of  6% red spinach powder is the best treatment with an increased color brightness value of 5,63.

AbstractStrawberry is an important horticultural crop in Florida. The long growing season and escapes from fumigation and PRE herbicides necessitate POST weed management to maximize harvest potential and efficiency. Alternatives to hand-weeding are desirable, but clopyralid is the only broadleaf herbicide registered for use. Weed control may be improved by early-season clopyralid applications, but at risk of high temperature and increased strawberry injury. The effect of temperature on clopyralid safety on strawberry is unknown. We undertook a growth chamber experiment using a completely randomized design to determine crop safety under various temperature conditions across acclimation, herbicide application, and post-application periods. There was no effect of clopyralid on the number of strawberry leaves across all temperatures. Damage to the strawberry manifested as leaf malformations. Acclimation temperatures affected clopyralid-associated injury (p=0.0309), with increased leaf malformations at higher temperatures (27 C) compared to lower (18 C) temperatures. Pre-treatment temperatures did not affect clopyralid injury. Post-application temperature also affected clopyralid injury (p=0.0161), with increased leaf malformations at higher temperatures compared to lower ones. Clopyralid application did not reduce flowering or biomass production in the growth chamber. If leaf malformations are to be avoided, consideration to growing conditions prior to application is advisable, especially if applying clopyralid early in the season.

In this study the effect of cold and heat shock on androgenetic induction in soybean anther culture was tested. Anthers of soybean were subjected to 4 and 33ºC, while the anthers used for control were maintained at 25ºC. Cytological analysis done during the 30 days of culture showed that frequencies of symmetrical binucleated and multicellular pollen grain did not differ among temperature treatments. Multicellular pollen grain could be formed by symmetrical division, as well as by assymetrical division. In relation to the embryo induction, the results of the treatments did not differ too. These results suggested that these treatments did not induce a sporophytic pathway in soybean.

Catfish (Clarias gariepinus.) is one of the leading commodities that are widely cultivated in Indonesia. The current development of the aquaculture industry, which leads to intensive cultivation systems with an increase in stocking and high amount of feed, causes an increase in organic waste that can reduce water quality. Phytoremediation is one way to stabilize pollutants, both organic and inorganic compounds, through aquatic plants. Water hyacinth (Eichornia crassipess) is one aquatic plant that can reduce total nitrogen up to 73.05%. This study aims to analyze the effect of water hyacinth (E. crassipess) as a phytoremediator on TAN reduction, survival rates, and growth of catfish (C. gariepinus) seeds. This study used a Completely Randomized Design (CRD) method with four treatments and four replications, namely P1 / control (without water hyacinth), P2 (without replacement of water hyacinth), P3 (alternation of water hyacinth every 21 days), and P4 (alternation of water hyacinth) every 14 days). The results showed that the P4 treatment (alternation of water hyacinth every 14 days) gave the lowest TAN content 0.01 mg / L and provided the highest survival rate of 89.88%, as well as the absolute weight and length growth of the most catfish seeds height, i.e., 9.80 g, and 5.50 cm, respectively.
