Asian sea bass, Lates calcarifer

Lates calcarifer, commonly known as the Asian sea bass or barramundi, is an 16 interesting species that has great aquaculture potential in Asia including Malaysia and also 17 Australia. We have investigated essential fatty acid metabolism in this species, focusing on 18 the endogenous highly unsaturated fatty acid (HUFA) synthesis pathway using both 19 biochemical and molecular biological appro...

Acute and postexposure effects of ammonia toxicity on juvenile barramundi (Lates calcarifer [Bloch]).

Lethal and sublethal effects of ammonia toxicity to juvenile barramundi (Lates calcarifer) were investigated under laboratory conditions following the OECD guidelines for testing of chemicals. Acute toxicity was tested in a static nonrenewal system at pH 9.0 and temperature around 29 degrees C. The 24-, 48-, and 96-h LC(50) values for barramundi were 3.89, 3.67, and 3.31 mg total ammonia N L(-1...

The Accumulation of Heavy Metals in Hydrostemma Motleyi Hook. f. Mabberlay and Hydrilla verticillata Casp

Pengambilan logam berat (kuprum, zink, nikel, kadmium dan kromium) oleh Hydrostemma motleyi (Hook.f.) Mabberlay dan htydrilla verticillata Casp. telah dikaji. Umumnya pengambilan logam bertambah bila kepekatan logam bertambah. Faktor pertambahan yang menghubungkan paras logam dalam tubuhan dengan paras logam dalam iarutan ber&urang bila kepekatan logam bertambah. Tindakan antagonistik diperhati...

Nitrite Content of Some Foods in Malaysia

Nitrat and nitrit adalah bahan tambah yang biasa digunakan dalam pengkiuran daging. Bahan-bahan ini juga memberi warna dan perisa yang baik dan dapat merencat penumbuhan mikroorganisma Clostridium botulinum. Nitrit boleh bertindak dengan amina sekunder dan membentuk sebatian nitrosamina. Nitrosamina inilah yang menjadi satu kontroversi berhubung dengan penggunaan nitrit kerana nitrosamine ini m...
