“…Some noteworthy publications reporting the effects of different diets and environmental factors on growth and general condition of the fish are reviewed here. De et al (2016) studied the effect of diet and temperature on growth and gastric emptying rate of TGGG. They noticed that the temperature elevation between 26°C and 30°C positively affected the growth whereas increase to 34°C and decrease in the range 26-22°C adversely affected this process.…”

The hybrid grouper discussed in this paper is a cross between female tiger grouper (Epinephelus fuscoguttatus) and male giant grouper (Epinephelus lanceolatus). Performed for the first time at this institute, the hybridization was motivated by the need to meet grouper demand. The hybrid has been a subject of thorough scientific investigations ever since it was produced. Qualities such as dietary needs, efficiency in growth and production and environmental resilience are of considerable aquaculture advantage, and account for interest in its commercial-scale farming in the wider Asia-Pacific region. This paper reviews scientific evidences on tolerance of hybrid grouper to environmental variability, nutrition, growth and genetic and other aspects. It makes serious attempt to summarize the pertinent data published on specific research questions to improve understanding of the diverse evidences, and to be able to identify gaps in knowledge. This has helped in articulating the current state of research and defining topics for future studies on the hybrid. From the analysis of published data it is obvious that hybrid has a higher production potential and resilience. Nevertheless, the hybrid is vulnerable to health problems linked to nutritional deficiencies and other factors. More comprehensive data on dietary requirements of the hybrid, especially larval stages, will help in formulating feeds that cater to metabolic requirements and improve the survival and biomass gains. Information on hybrid's dietary flexibility can be used in developing feeds for grow-out stages comprising ingredients from sustainable sources. The hybrid could be a suitable candidate for adapting aquaculture to climate change.

“…Apart from salinity, the diet itself plays a vital role in the physiology and growth of fish (Ashley, 2007). The combined effects of temperature and diet (pellet and shrimp) on growth performance of TG×GG hybrid grouper has been documented recently (De, Ghaffar, Bakar, & Das, 2016). Meanwhile, combination of salinities and diets effects on growth have been described for juvenile sole, Solea sole and S. senegalensis (Imsland, Foss, Gunnarsson, & Berntssen, 2001).…”

The influence of salinities and diet on growth performance of tiger grouper (Epinephelus fuscoguttatus) × giant grouper (E. lanceolatus) (TG×GG hybrid), was investigated. TG×GG hybrid (10.0 ± 0.5 cm initial length and 50.5 ± 2.0 gram initial weight) were subjected to different salinities (10, 15, 20, 25 and 30 part per thousand (ppt)) and two diets, commercial pellet (42% protein, 9% ash, 11% lipid, 9% moisture) or trash fish, Sardinella fimbriata (70%protein, 15%ash, 4%lipid, 76% moisture) in triplicates with 15 fish per replication. At the end of the experiment (60 days), the final length, weight, feed consumption (FC), feed conversion ratio (FCR) and specific growth rate (SGR) were calculated. The highest mean SGR (1.05± 0.02% BM day -1 , P<0.05) was observed in the 15 ppt + pellet group of fish, while the lowest SGR was observed in the 30 ppt + trash fish group (0.40 ± 0.05% BM day -1 , P<0.05). The highest FC was significantly (P<0.05) observed at 15 ppt on both diets. The lowest FCR (1.21± 0.15, P<0.05) was observed in the 15 ppt on pellet diet. The results denotes that 15 ppt fed with commercial pellet is the optimum condition for growth performance of TG×GG hybrid grouper juveniles.

“…Overall measurement of the physical and chemical parameters of water resulted categorized in reasonable value ranges for grouper culture activities using floating net cage. Based on a recent study conducted in Malaysia, the optimum temperature for the cultivation of grouper is 26 and 30 °C (Moumita De et al, 2016). Putri et al (2013) state that the growth of groupers will be optimum at a temperature range of 29-31 °C and salinity of 33 g/L.…”

Grouper Epinephelus sp. farming activities in Lampung Bay is limited to an area of 77 hectares, while areas that are potential to be used for grouper farming are still very wide. Therefore, this study aimed to assess the suitability of Lampung Bay waters for grouper farming activities. The study was conducted in 20 stations with ecological preference considerations. The parameters observed were physicochemical (water depth, temperature, water transparency, the load of suspended solids, pH, dissolved oxygen, salinity, nitrate, and phosphate) and biological parameters (phytoplankton abundance and chlorophyll-a concentration). After the data were completely obtained, the data were processed into suitability matrix resulting in scores that will be grouped into four classes, namely S1 (highly suitable), S2 (moderately suitable), S3 (marginally suitable), N (not suitable). The geostatistical model was used to perform the earth's surface mapping based on biotic and abiotic parameters that were analyzed. Based on the results of the analysis in this study, the conditions of Lampung Bay waters were suitable for grouper farming activities. Marine area that could be used for grouper farming was 33,847.12 hectares (S1: 15,712.6 ha, S2: 13,294.7 ha and S3: 4,209.82 ha) in the area around Puhawang Island, Kelagian Island, Maitem Island, Tegal Island to Hurun Bay.Keywords: Lampung Bay, grouper, suitability analysis, fish farming ABSTRAKKegiatan budidaya ikan kerapu Epinephelus sp. di Teluk Lampung masih terbatas pada lahan seluas 77 hektar, sedangkan lahan yang berpotensi digunakan untuk budidaya ikan kerapu masih sangat luas. Oleh karena itu, penelitian ini bertujuan mengkaji kesesuaian perairan Teluk Lampung untuk kegiatan budidaya ikan kerapu. Penelitian dilakukan di 20 stasiun dengan pertimbangan ecological preference. Parameter yang diamati yaitu parameter fisika-kimia perairan (kedalaman, suhu, kecerahan, muatan padatan tersuspensi, pH, oksigen terlarut, salinitas, nitrat, dan fosfat) serta parameter biologi (kelimpahan fitoplankton dan konsentrasi klorofil-a). Setelah data parameter terpenuhi, data diolah ke dalam matriks kesesuaian sehingga menghasilkan skor yang akan dikelompokkan ke dalam empat kelas, yaitu S1 (highly suitable), S2 (moderately suitable), S3 (marginally suitable), N (not suitable). Model geostatistik digunakan untuk melakukan pemetaan permukaan bumi berdasarkan data parameter biotik dan abiotik yang dianalisis. Berdasarkan hasil analisis pada penelitian ini, kondisi perairan Teluk Lampung sesuai untuk kegiatan budidaya ikan kerapu. Luas perairan laut yang dapat digunakan untuk kegiatan budidya ikan kerapu yaitu, 33.847,12 hektar (S1: 15.712,6 ha, S2: 13.294,7 ha dan S3: 4.209,82 ha) di daerah sekitar Pulau Puhawang, Pulau Kelagian, Pulau Maitem, Pulau Tegal hingga Teluk Hurun.Kata kunci: Teluk Lampung, ikan kerapu, analisis kesesuaian, budidayaOriginal Article
