Impact of three different types of seaweed diets on growth, feed utilization and nutrient digestibility of L. rohita was studied for 120 days. The seaweed diet fed fishes, especially Ulva based diet showed comparatively higher growth and weight increment. Good food conversion ratio, food assimilation efficiency, protein efficiency ratio and better nutrient digestibility were recorded for seawee...

Two genera and nine species of Peridinetini are recognised in the West Indies; four of the species are newly described. Peridinetus Schönherr is represented in the Greater Antilles by P. concentricus (Olivier), P. decipiens Prena sp. n., P. fuscosignum Prena sp. n., P. poeyi Jacquelin du Val stat. res., P. roeselii (Boheman) and P. sexguttatus (Fabricius) comb. n. and Palliolatrix Prena in the ...

Procedures for impact assessment, including “beyond-BACI” (before–after control–impact) and proportional differences (ratios between impact and control treatments) were used to test population replenishment of marine invertebrates at a marine conservation area (MCA) and three fished (control) areas in the Solomon Islands of the southwestern tropical Pacific. Within shallow reef terrace habitat,...

Two new triterpene glycosides, scabraside A (1) and B (2), and a structurally known compound (3), were isolated from the sea cucumber Holothuria scabra (Holothuriidae) collected from the South China Sea. Structure of these compounds was elucidated by spectroscopic and chemical methods. The glycosides 1 and 2 exhibit the same common structural features, i. e., the presence of 12- and 17-hydroxy ...

conclusions our results suggest that h. parva and h. oculata may be promising therapeutic candidates for the treatment of hcc, following further confirmatory in vivo experiments and clinical trials. results our results showed that h. parva methanolic extracts (250, 500, and 1000 µg/ml) and h. oculata methanolic extracts (200, 400, and 800 µg/ml) increased reactive oxygen species (ros) formation...
