Having a deep genetic structure evolved during its domestication and adaptation, the Asian cultivated rice (Oryza sativa) displays considerable physiological morphological variations. Here, we describe whole-genome sequencing of aus cultivar Kasalath by using advanced next-generation (NGS) technologies to gain better understanding sequence structural changes among highly differentiated cultivars. The de novo assembled sequences represented 91.1% (330.55 Mb) genome contained 35 139 expressed...
The present study aimed to determine the current status of corals using coral video transect (CVT) method in east coast, west and isolated areas Tioman Island, Peninsular Malaysia. A total 65 genera from 21 families were identified, which scleractinian Acropora, Montipora, Porites dominant assemblages. Nine reef sites categorised as having 'good' (51.4%-60.3%) condition four 'fair' (37.6%-49.2%) condition. This concluded that reefs around Island average have high generic diversity with mixed...
Relationships between weights (W, dry weight [DW] and wet [WW] lengths L, standard length [SL], head [HL], caudal peduncle depth [CD]) these DW WW were examined in 61 freshwater fishes using formula W = a L b , respectively. The parameters of the SL–DW, SL–WW, HL–DW, HL–WW, CD–DW, CD–WW, WW–DW relationships determined for 60, 61, 57, 58, 50, taxa, respectively, with criterion where estimated R‐square was greater than 0.8. For genus or higher taxonomic level, SL–DW SL–WW 20 groups same to...
African catfish Clarias gariepinus hatched with morphologically immature features; however, sensory organs developed rapidly fish growth. Although the eyes of newly larvae were without pigment, in 2 day‐old larvae, retina had already except for rod cells. No free neuromasts observed larvae. In 1 on head and trunk. Free increased larval Newly simple round‐shaped otic vesicles; all epithelia inner ear until 3 days old. Two swam horizontally, sharp teeth, commenced ingesting rotifers also...
The present study was conducted to elucidate the relationship between larval feeding behavior of African catfish, Clarias gariepinus and their sensory organs. We also sought reduce cannibalism improve rearing methods for this species. intact streptomycin-treated larvae examined under light dark conditions using Artemia nauplii. ingestion rates versus did not vary significantly; furthermore, no difference observed larvae. These results showed that C. depends on chemo-sensory senses rather...
In general, African catfish shows higher survival rates in the dark conditions than light conditions. this study, larval behavior of was observed under 0, 0.01, 0.1, 1, 10, and 100 lx using a CCD camera to investigate reason why larvae show The showed significantly swimming activity 0.1 that 10 lx. also increased aggressive lx; attacked resting individuals more frequently sharp teeth attacking appeared induce skin surface lesions on injured larvae. Chemical substances were then generated...
Free mechanosensory neuromasts of larval fishes have been described as playing a complementary role to vision in feeding behaviour (Disler, 1971; Iwai, 1972a,b). In certain species or under limited conditions, free play major detecting prey. The larvae mottled sculpin Cottus bairdi can feed on Artemia the dark by using (Jones and Janssen, 1992). Artificially blinded surface-feeding Aplocheilus lineatus detect insects water surface means (Muller Schwarts, 1982; Tittel et al. 1984; Bleckmann,...
Fish Hunger behaviour is one of the important element in determining fish feeding routine, especially for farmed fishes. Inaccurate routines (under-feeding or over-feeding) lead fishes to die and thus, reduces total production The excessive food which not eaten by will be dissolved water reduce quality (oxygen quantity reduced). reduction oxygen (water quality) leads some cases, may diseases. This study correlates Barramundi fish-school with hunger condition through hybrid data integration...
The morphogenesis of sense organs and related behavioural changes in the hatchery-reared brown-marbled grouper Epinephelus fuscoguttatus larvae were examined to gain better understanding its early life history because ecological field observations for species is difficult. newly hatched (2.1 mm total length) had developing eyes otic vesicles, a pair free neuromast on head ciliated olfactory epithelium. At 3 days post hatching (dph), became fully pigmented with pure-cone retinae, semicircular...
Larvae and juveniles of barramundi Lates calcarifer (Bloch) were examined for the development retina, occurrence retinomotor response retinal tapetum change in eye size with age days. The hatched unpigmented non-functional eyes which cells had not yet differentiated into various elements. Soon it was followed by rapid changes histology retina. Two-day-old larvae a well-pigmented retina area temporalis would allow acute vision prey attack nasal direction. At 10 days, rod first appeared...
The capability of planktonic yolk-sac larvae red sea bream Pagrus major in detecting food was examined the laboratory to ascertain basic knowledge on early life history this marine fish. After infrequent vertical burst swimming followed by slight rising or sinking, remained motionless within thin layers concentrated extract (rotifer, Brachionus plicatilis). At moment hatching, already have receptor cells with several cilia arranged radially their open nostrils. Thus it is likely that means...
Cochlodinium polykrikoides is known as fish killer. In Malaysia this species has been recorded in Kota Kinabalu, Sabah, Borneo Island. To date, C. not Peninsular Malaysia. This study aims to identify the presence of particularly Tanjung Piandang, Kuala Kurau and Gula located Perak coastal waters Straits Tebrau, Johor. Samplings were carried out for three times at each sampling station. Ten litre water samples collected cell enumeration identification. For identification, plankton identified...
The sutchi catfish, Pangasianodon hypophthalmus is an important species for aquaculture in Southeast Asia. However, the larvae demonstrate a low survival rate due to their strong cannibalism during rearing. aim of present study was reduce and improve larval rearing methods. Larval experiments were conducted under normal light conditions (following diel rhythm) continuous dark with densities 10, 20 40 individuals L-1 from hatching day days old. trial 10 had highest rate. lower individual...
A study on diversity of phytoplankton was carried out in the coastal water Kuantan, Pahang, Malaysia. Eighteen samples seawater were collected from six stations September 2011 to March 2012. This aimed identify phytoplankton, determine species abundance and diversity. Physico-chemical parameters such as pH, salinity, temperature dissolved oxygen recorded. Based light microscopy, 70 taxa composed 63 diatoms 7 dinoflagellates identified. Bacteriastrum delicatulum, Chaetoceros spp.,...
This study was conducted to clarify the development of free neuromasts with growth barramundi, Lates calcarifer. A pair observed behind unpigmented eyes in newly hatched eleutheroembryos a mean total length 1.93 mm, and two-hour-old eleuthero-embryos could respond an approaching pipette. At 2 days after hatching, egg yolk sac mostly consumed, were pigmented, larvae commenced feeding on rotifers. Free increased number developing into canal barramundi 15 old 8.07 mm. The average major axis...
Mangroves composition and species are richly diverse in Tioman Tulai Island. A total of 23 mangrove have been found consisting exclusive non-exclusive Kg. Juara, Nipah, Paya, Genting The abundance Rhizophora X lamarckii, apiculata, mucronata Brugueira gymnorrhiza. From supervised classification, 59.90 hectares covers identified both islands, with 86.49% Island (52.76 hectares) 13.51% (7.14 hectares). new hybrid has (Rhizophora lamarckii) dominated Island, combination between stylosa...
