Shrimp is a very important source of protein which patronized by almost half the world's population, and hence specie in aquaculture. There need for increase shrimp production worldwide to meet consumer demands. However, hampered high cost commercial feeds. Increase prices fish oil meal has led calls their substitute. This substitute resulted researchers studying nutritional requirement shrimp. The rationale this article review literature available on recent studies toward development...

Coelomactra antiquata is an important aquatic economic shellfish with high medicinal value. However, because C. has no reference genome, a lot of molecular biology research cannot be carried out, so the analysis its transcripts step to study regulatory genes various substances in antiquata. In present study, we conducted first full-length transcriptome by using PacBio single-molecule real-time (SMRT) sequencing technology. The results identified total 39,209 unigenes average length 2,732 bp,...

Abstract Lutjanus fulgens (Valenciennes, 1830) is a teleost species classified under the family Lutjanidae which native of Eastern Atlantic Ocean. Though highly commercialized due to its abundance and good taste, production output has declined in recent years. This an indication need for effective management conservation measures. However, accurate identification will ensure strategic measure. DNA‐based proven reliability this regard via precise identification. Several researchers have...

Norethisterone (NET) is one of the earliest synthetic progestins. Its widespread and long-term use means that NET often detected on surface in groundwater samples, which may cause harm to aquatic organisms. Marine medaka (Oryzias melastigma) a brackish fish, used ecotoxicology studies. In this study, effect norethisterone exposure transcriptome marine larvae was analyzed. Larvae were exposed 10 ng/L for 24 h, then RNA-Seq performed. Exposure resulted 306 up-regulated 516 down-regulated...

Lutjanus erythropterus (Bloch, 1790), a Perciformes from the Lutjanidae family, is commercially important species because of its taste and abundance. Despite increase in genome resources recent years, few assemblies are available within this fish family for comparative functional studies. In study, we determined chromosomal Crimson snapper using high-throughput Single-Tube Long Fragment Reads sequencing technology Hi-C data. The final assembly size was 973.04 Mb with contig scaffold N50...

Peanut worm, Sipunculus nudus is a cosmopolitan species found in inter-tidal sands. In this article, based on the samples collected from Beibu Gulf, China, mitochondrial DNA sequence by Illumina high throughput sequencing, was carried out muscle and determined complete mitogenome. This mitogenome of peanut worm 15,331 base pairs length (Accession number: MN481531) comprises 37 genes as typical gene arrangement Sipunculus. Moreover, phylogenetic analysis shows that our sample novel type China...

Fish meal and fish oil have been the mostly used ingredients (protein lipid respectively) in aquaculture feeds due to their excellent source of well-balanced amino acid profile n-3 long chain polyunsaturated fatty acids (LC-PUFA) respectively. However, escalating prices fluctuation production, there are calls for alternative protein sources be used. Plant based recognized as alternatives that could enhance growth performance well reduction cost production. The regulation muscle by plant...
