<p>Several types of grouper hybrid seeds can now be massively produced in a hatchery. Hybrid seeds can increase diversification of aquaculture species and potential to increase fish production.  Therefore, an  improvement in hybrid seed production both in high quantity and quality is very important. This research was conducted to produce massively cantik grouper hybrid seeds i.e.,a crossbreed between female tiger grouper (Epinephelus fuscoguttatus) and male marbled grouper (Epinephelus microdon). This research examined the cantik grouper seed production compared with the production of tiger grouper and marbled grouper fingerlings. The research results showed that cantik hybrid grouper seeds production had higher survival rate (24.59%) than tiger grouper (17.44%) and marbled grouper (4.63%). The total length of the seed at the age of 45 days for cantik grouper  was 3.59 ± 0.21 cm, tiger 3.24 ± 0.55 cm, and batik 2.61 ± 0.42 cm, respectively. Seed abnormality for cantik grouper was 4.13%, tiger grouper 30.21%, and marled tiger 0.57%, respectively. Based on genetic variation analyses, the cantik grouper had a closer genetic relationship with the marbled grouper compared with the tiger grouper.</p> <p>Keywords: Marbled grouper, hybridization program, seeds production, quality</p>

AbstrakKerapu cantik merupakan kerapu hibrid hasil persilangan antara betina kerapu macan dan jantan kerapu batik. Salah satu permasalahan dalam pembenihan kerapu cantik secara umum, yaitu pertumbuhan stadia awal benih kerapu cantik yang lambat. Permasalahan tersebut dapat diatasi dengan menambahkan taurin pada pakan buatan untuk meningkatkan pertumbuhan benih ikan kerapu cantik.Penelitian ini bertujuan untuk mengetahui pengaruh penambahan taurin pada pakan buatan terhadap pertumbuhan dan sintasan benih ikan kerapu cantik. Penelitian ini menggunakan metode RAL dengan tiga perlakuan, yaitu pemberian pakan buatan dengan kadar taurin 0% (P1), 0,5% (P2) dan 1% (P3) yang diberikan pada benih ikan kerapu cantik dan masing-masing perlakuan diulang enam kali. Hasil pemeliharaan selama 45 hari menunjukkan bahwa penambahan taurin sebesar 1% pada pakan buatan memberikan pertumbuhan tertinggi dibandingkan perlakuan lainnya dan berbeda nyata (p<0,05). Penambahan taurin 1% pada pakan buatan tidak memberikan hasil sintasan yang berbeda dengan kontrol (taurin 0%). AbstractCantik grouper is hybrid grouper, it is the results of a crossover between females tiger grouper and males batik grouper. One of the problems in breeding cantik grouper in common is the growth of early stadia juvenile cantik grouper is slow. This problem could be solved by added taurine in the feed to increase the growth of juvenile cantik grouper. The purpose of this research is to find the influence of the addition of taurine in the feed on the growth and survival rate of juvenile cantik grouper. This research used completely randomized design (CRD) method with three treatments, which is giving taurine to feed with 0 % (P1), 0.5 % (P2) and 1 % (P3) concentration given to the juvenile cantik groupers and the treatment has been repeated six times. The results of breeding for 45 days showed that the addition of 1 % taurine in feed give the highest growth than other treatment and differs markedly ( p<0.05 ). The addition of 1% taurine gives no different result with the control variable (0% taurine).

Transport in water is the most common method for achieving high survival rates when transporting cultured fish in China; yet, transport success relies on proper water quality and conditions. This research was designed to explore the effects of ascorbic acid and β-1,3-glucan on survival, physiological responses, and flesh quality of farmed tiger grouper (Epinephelus fuscoguttatus) during simulated transport. The transport water temperature for live tiger grouper was 15 °C, which had the highest survival rate, the lowest stress response, and metabolic rate, and this will reduce the susceptibility to diseases. It is stated that β-1,3-glucan influences the changes of cortisol content, heat shock protein 70, IL-1β, and IgM transcription levels during simulated transport. Rather than using ascorbic acid alone (the A-group), β-1,3-glucan (3.2 mg/L) in the presence of ascorbic acid (25 mg/L) can effectively reduce the increase of transport-induced serum cortisol content, heat shock protein 70, and IL-1β, but stimulated IgM. 25 mg/L ascorbic acid and 3.2 mg/L β-1,3-glucan had no obvious effect on the nutritional indexes and flavor of live tiger grouper; however, these can effectively reduce the stress response, improve the innate immune activity, and ensure a higher survival rate.

The effect of ovule and ovary position on the frequency of hybrid seed production of faba bean (Vicia faba L.) was measured at Dijon, France and Saskatoon, Canada. Even though there was far greater ovule fertilization frequency at Dijon (72%) than at Saskatoon (30%) the frequency of hybrid seed was significantly greater at Saskatoon (24%) than at Dijon (15%). Neither the position of the ovule within the ovary nor the position of the raceme on the stem had any effect on the production of hybrid seed. However, at both locations the highest position within a raceme produced a significantly greater proportion of hybrid seeds. It is proposed that under the effect of intra- or inter-plant stress, developing ovaries containing hybrid embryos may be selectively retained.Key words: Vicia faba, ovule fertilization, outcrossing, faba bean

Abstract From the sociology of science perspective, this paper attempts to trace the shifts in the knowledge and its application in the context of seed production—the central input in agriculture. The paper argues that the seed production, which was once in the hands of farming communities, has become industrialized with the advent of hybrid seeds. The hybrid seed production, based on phenotypic knowledge of the plants, marks the first phase of the industrialization of seed and the genetically modified seed, based on genotypic knowledge of the plants, marks the beginning of another phase in the industrialization of seed production. This paper draws attention to controversies over genetically modified seed based on economic, social, environmental considerations. This paper also discusses the implications of these developments and the changes in the institutional arrangements that govern the production and use of the seed, as these developments have profound implications for Indian agriculture and agrarian relations.

<p><em>Indonesia is an archipelagic country with many locations suit for aquaculture. Grouper hatcheries are still concentrated in a few locations. Therefore, appropriate technology to transport live grouper seed is needed to ensure the survival and health of the seed. This study aimed to determine the duration of fasting before transportation and the optimum density of grouper seed during transportation. Transportation was conducted in closed system, transported using a car, for 24 hours. Grouper seed used for the experiment was cantik hybrid grouper, a cross-breed between </em><em>female tiger grouper </em><em>(Epinephelus fuscoguttatus) and male marbled grouper (Epinephelus microdon)</em><em> with an average of size </em><em>7</em><em>.</em><em>0±0</em><em>.</em><em>32 cm</em><em>. There were 2 experiments in this study. Experiment 1 was different durations of fasting before transprotation: A. 12 hours, B. 24 hours, C. 36 hours and D. 48 hours with the density of 150 seeds/boxes. The result of the first experiment was used to determine the experimental design of experiment 2, which consisted of 4 different densities per boxes: A. 125 seeds, B. 150 seeds, C. 175 seeds and D. 200 seeds. Both of the experiments were conducted in triplicates. The seeds were packed in plastic bags with a thickness 0.08 mm, length 120 cm x width 53 cm, filled with 10 liters of sea water. The results showed that the duration of fasting from 36 to 48 hours had the highest survival rate.
