Development of digestive enzyme activity in spotted rose snapper, Lutjanus guttatus (Steindachner, 1869) larvae

Fish Physiology and Biochemistry, 2013
We describe digestive enzyme activity during the larval development of spotted rose snapper, Lutjanus guttatus. Trypsin, chymotrypsin, leucine aminopeptidase, pepsin, amylase, lipase, and acid and alkaline phosphatase activities were evaluated using spectrophotometric techniques from hatching through 30 days. The spotted rose snapper larvae present the

Expression and activity of trypsin and pepsin during larval development of the spotted rose snapper Lutjanus guttatus

Comparative Biochemistry and Physiology - B Biochemistry and Molecular Biology, 2012
The present study aimed to describe and understand the development of the digestive system in spotted rose snapper (Lutjanus guttatus) larvae from hatching to 40 days post-hatch (dph). The mouth opened between 2 and 3 dph, at that moment the digestive tract was barely differentiated into the anterior and posterior intestine, although the liver and ...

Hematological characteristics of the spotted rose snapper Lutjanus guttatus (Steindachner, 1869) healthy and naturally infected by dactylogyrid monogeneans

Tissue and Cell, 2011
The aim of the present study was to obtain a basic knowledge of the hematology in order to determine changes in blood parameters of the spotted rose snapper Lutjanus guttatus. The morphological features of blood cells were described according to the observations made by light microscopy of Wright-Giemsa-stained blood films.

Growth Performance of Spotted Rose Snapper in Floating Cages and Continuous Water-Flow Tank Systems

open access: yesNorth American Journal of Aquaculture, 2015
Abstract Growth performance of hatchery-reared Spotted Rose Snapper Lutjanus guttatus reared at two culture systems were studied, discussed and compared. We stocked 150 juveniles (mean, 124 g) into each of three floating cages and three onshore tanks (3 m3) supplied with seawater of similar temperature (range 23–29°C).

Toxic effect of the harmful dinoflagellate Cochlodinium polykrikoides on the spotted rose snapper Lutjanus guttatus

open access: yesEnvironmental Toxicology, 2009
AbstractThe dinoflagellate Cochlodinium polykrikoides isolated from Bahía de La Paz, Gulf of California, showed an important short‐term toxic effect on the spotted rose snapper Lutjanus guttatus. This microalga was able to decrease fish liver catalase activity and lipid peroxidation.

Use of Copepods during Early Feeding Stages of Spotted Rose Snapper Larvae in a Scale-Up System

North American Journal of Aquaculture, 2015
Abstract Growth but not survival of Spotted Rose Snapper Lutjanus guttatus larvae was improved when calanoid copepods Pseudodiaptomus euryhalinus were included as early feed in a pilot-scale production system. Production of P. euryhalinus that were fed microalgae Nannochloropsis oculata was stable through the snapper spawning season (May–

Age, growth, and mortality of the spotted rose snapper Lutjanus guttatus from the southeastern Gulf of California

Fisheries Research, 2006
Abstract The age of the spotted rose snapper Lutjanus guttatus over the continental shelf of the southeastern Gulf of California was estimated by examining transverse sections of their sagittal otoliths. Individuals (238) collected from summer 2001 to spring 2003 were analyzed.

Genetic connectivity in the spotted rose snapper Lutjanus guttatus (Lutjaniformes: Lutjanidae) between Mexico and Panama throughout the Tropical Eastern Pacific

open access: yesNeotropical Ichthyology, 2023
The spotted rose snapper, Lutjanus guttatus, is an important fishery species with high potential for aquaculture. Genetic characterization of its natural populations is necessary to avoid stock collapse and loss of genetic diversity.
