    Echo-sounder imaging for fish stock size estimation
    (Universiti Teknologi Malaysia, 2011-07) Mohd Fazrul Hisam Abd Aziz
    This study emphasizes on the characterization of echo-sounder backscatters for fisheries application at micro level by remote sensing techniques. A method for acoustic-based fish stock size estimation by vertical echo-sounder of fish schooling in the mid-water area of East Coast of Peninsular Malaysia (ECPM) was carried out. The specific objectives of this study are: (a) to estimate stock size of pelagic species based on backscatters acquired by echo sounder imaging; (b) to map the density of three pelagic fish species, i.e. Round Scad, Torpedo Scad and Ox-eye Scad; and (c) to analyse the relationship of vertical distribution of multi-species pelagic fish with surrounding biophysical parameters (dissolved oxygen, temperature and salinity).

    Otolith based age and growth studies on the indian oil sardine, sardinella longiceps (valenciennes, 1847) from Muscat, Sultanate of Oman
    (Terengganu: Universiti Malaysia Terengganu, 2012-03) Al-Anbouri, Ibrahim Said
    The Indian oil sardine Sardinella longiceps is a commercially important small pelagic resource in the Indo-Pacific region. Although, this species forms a considerable proportion in the fish catches of Oman, no detailed studies on the biological characteristics of this fish have been attempted. Hence, a study was carried out to investigate growth parameters using analysis of otolith dimension and length frequency, population parameters using analysis of otolith dimension and length frequency, age at 1st maturity using analysis of otolith dimension and gonad maturation and spawning season analysis of otolith dimension and gonad maturation.

    Effect of thermal shock on hsp70 expression and innate protection against vibrio infection in the white-leg shrimp Litopenaeus vannamei (Boone, 1931)
    (Terengganu: Universiti Malaysia Terengganu, 2012-06) Nguyen, Hong Loc
    Exposure to long-term hyperthermic stress disrupts the normal physiological processes of shrimp, and under severe conditions may decrease immune response towards disease and infection, resulting in mortality. Short-term heat stress, however, promotes bacterial and viral disease tolerance, possibly due to heat shock protein 70(Hsp70) accumulation and/or immune enhancement.

    Morphological characteristics and genetic analyses on triploid African catfish (Clarias gariepinus)
    (Terengganu: Universiti Malaysia Terengganu, 2012-09) Normala Jalil
    Triploids are organism with three chromosome sets. They are known to be sterile and easily induced in many species of fish and shellfish. However, suitable and rapid method for triploid identification for large scale production is still limited. This is due to the inability to accurately determine this characterization which currently is determined based on erythrocyte and karyotyping method. The specific objectives of this study were to determine the erythrocyte size, morphometric characteristic and genetic variation in triploid African catfish.

    Incorporation of dried water hyacinth, Eichhornia crassipes in red tilapia, Oreochromis mossambicus x O. niloticus fingerlings feeds
    (Terengganu: Universiti Malaysia Terengganu, 2012-11) Abdel-Rahman Tibin, Mubarak Eisa
    Traditionally, fish meal has been utilized extensively in aqua-feeds, mainly due to its high nutritional properties. However, various reasons dictate the utilization of sustainable alternatives and minimizing the dependence on this commodity in fish feeds. Lack of affordable fish feeds is one of the major constraints facing small- scale fish farmers as most of the fish feed is imported by majority of the countries practicing aquaculture. Hence, the aim of the present study was to evaluate the nutritional potential of the water hyacinth(WH), Eichhornia crassipes dried meal and also to investigate effects on nutrients digestibility growth performance and feed utilization of dried WH meal incorporated in feeds fed to fingerling hybrid red tilapia, Oreochromis mossambicus x O. niloticus.

    The effect of salinity exposure on the gene expression in the Pangasius nasutus (Bleeker, 1863) muscle
    (Terengganu: Universiti Malaysia Terengganu, 2013-01) Nabilah Mohamad Ali
    Salt has been the traditional remedy used in aquaculture industry which is also widely applied in the culture practice of pangasids. With the extensive use of salt in the aquaculture industry, the study on Pangasius nasutus molecular responses in the muscle tissue towards salinity exposure is still limited. Due to this, a study was carried out to identify genes that were expressed during salinity exposure in the muscle tissue of P. nasutus.

    (Terengganu: Universiti Malaysia Terengganu, 2013-05) Arief Izzairy Zamani
    Recognition proteins play an important role in the immunodefense system of invertebrates. Thus, present study aimed to isolate a recognition protein, via Heparin column from Slipper cupped oyster, Crassostrea iredalei haemolymph plasma to elucidate its roles in prophenoloxidase-activation systems (proPO) and to characterise it. The protein was isolated using affinity column chromatography with yield of 8% and a single peak.

    Growth performance and biochemical changes in nile tilapia, Oreochromis niloticus fed with varying dietary maltose level
    (Terengganu: Universiti Malaysia Terengganu, 2013-06) Ighwela, Keri Alhadi
    Tilapia is the second most consumed farmed fish, after carp, and the most widely grown of any farmed fish. Significant feed price increases in recent years threaten sustainability of the industry. Therefore, the objectives of the current study are to understand the interrelationship between malt-extracted maltose levels in the feed with growth parameters, body composition, apparent digestibility coefficients, haematological and biochemical changes in blood serum of Nile tilapia Oreochromis niloticus fingerlings (mean initial weight, 2.1 ±0.2 g). The fishes were fed with practical-type diets formulated containing five levels of dietary maltose (0.0, 20, 25, 30 and 35%) extracted from malted barley.

    (Terengganu: Universiti Malaysia Terengganu, 2013-07) Maziidah Ab. Rahman
    Current trend in drug discovery and modern pharmaceutical analysis have revolutionized in order to solve problems and meet the raising demand for humankind including remedies for disease. Since the utilization of antibiotics have been banned for aquaculture practices, new methods and technologies need to be implement to face the disease outbreaks. Therefore, the objectives of this study were to determine the biomedical properties in epidermal mucus and skin of the cleaner fish, Labroides dimidiatus, that have important roles in the defense mechanism since both are the first line defense of innate immune system.

    Behavioural And Physiological Changes Of Blue Swimming Crab, Portunus Pelagicus At Different Culture Temperatures
    (Universiti Malaysia Terengganu, 2018) Md Adib, Mohamad Nor Azra
    Inconsistent seed production and climate change cause problems for the crab culture industry. This study aimed to understand the effects of different water temperatures on the physiological conditions (survival, growth, molting, shell hardening, thermal tolerance, sexual differentiation and fatty acids compositions), behaviour, maturation and stress of blue swimming crab, Portunus pelagicus. In this study, P. pelagicus from first stage of instar were cultured at three different water temperatures (24 °C, 28°C and 32 ·C). Fatty acids composition in relation to maturation and stress were examined after certain physiological changes. Molting success as well as behaviour and hardening of the carapace were analyzed using a video recording with behavioural coding software and a novel hardness scale to obtain their physiological response. Meanwhile, thermal tolerance was calculated using a dynamic method and determination of stress on crab were carried out through histological examination of gills. The results indicate that the carapace width increased directly with temperature. Conversely, duration of the intermolt period was negatively correlated with temperature. The time of crabs' molting and carapace hardening were decreased with increasing temperature. The crab movement was positively correlated with temperature. Thermal tolerance increased directly with temperature. Monounsaturated Fatty Acids (MUFA) was the most abundant biochemical component, while Saturated Fatty Acids (SFA) represented a minor fraction of body compositions.
