consumo de oxigeno de larvas filosoma 1 de la langosta roja Panulirus interruptus ante variacion de temperatura y salinidad con iluminacion y oscuridad
Hidrobiologica, 2013Co-Authors: Antonio Silva, Eugenio Diaziglesias, Etelberto D SerranofloresAbstract:The purpose of this study was to ascertain the immediate responses of Panulirus interruptus phyllosoma larvae one day after hatching in regard to QO2 (µl O2 mg −1 h −1 ), in response to the combined variation of temperature (11,17, 22, 27 and 31 °C) and salinity (22, 28, 33.5 and 42 ups), in conditions of light and darkness. Their oxygen consumption was measured with polarographic equipment in closed chambers. A three-way ANOVA was applied to the data, and a highly significant (p < 0.001) effect was found in regard to temperature, salinity and light-darkness, on the QO2 of the larvae. The interaction between temperature and salinity was highly significant (p < 0.001); between temperature and light-darkness was not significant (p = 0.697); between salinity and light-darkness was significant (p = 0.016). The data were graphed as a response surface. The value for QO2 in hatching conditions (22 oC and 33.5 ups) was 1.8 and 3.7 times greater with respect to 11 oC and 33.5 ups and 11 oC and 42 ups respectively. The values for QO2 fluctuated between 0.12 and 0.86 µl

bioenergetics of red spiny lobster Panulirus interruptus randall 1840 juveniles fed with mollusc
Aquaculture, 2011Co-Authors: Eugenio Diaziglesias, Marysabel Baezhidalgo, Ana Karina Roblesmurillo, Rene J Buesa, Miriam LopezzentenoAbstract:article i nfo A study to determine of the energetic balance of the red spiny lobster Panulirus interruptus juveniles when fed with squid and mussels included dynamic respiratory measurements, determining oxygen consumption, ammonia excretion and calculating the atomic relationship O:N to estimate the metabolic substrate preferred. We concluded that 81.4% of the energy ingested (C) from the mussels was used for growth (P), and 52.4% when squid fed (Pb0.001). The eliminated energies (F) of 3.5 with mussels and 3.9% with squid were not significantly different (PN0.05). The nitrogenous excretions (U) were significantly different (PN0.05) with percentage values of 10.8 for mussels, and 1.1% for squid, respectively. The resting oxygen consumptions (R) of 15 and 5.1%, as well as the increase of apparent heat (AHI) of 18.2 and 8.6% were significantly different (Pb0.05), for squid and mussels, respectively. A ratio of 5.95 for oxygen-nitrogen (O:N) when squid fed indicates that proteins are used mainly as energetic substrate and consequently were not used in growth. In the case of mussels of ratio 22 it is significantly different (Pb0.05), which signifies that proteins mixed with lipids were used as energetic substrate, channeling obviously a part of the proteins for growth, in this case due to its superior nutritious quality. We conclude that the mussels (Mytilus galloprovincialis and M. californicus) as food for juveniles of P. interruptus covers the necessary energetic requirements representing a better food source under laboratory conditions, in aquaculture, and in formulating balanced diets. A survival rate of 100% was obtained during the 221 days of the study period. The initial average value of the cephalothorax length (CL) was of 6.91 mm, while wet weight was of 0.21 g and the final values after eight molts reached the 34.2 mm of CL and 35.393 g for wet weight; the increase of CL/day was of 0.12 mm at 19.4 °C.

Hidrobiologica, 2010Co-Authors: Eugenio Diaziglesias, Marysabel Baezhidalgo, Francisco Galicia Galicia, Luis Fernando Buckle Ramirez, Eric PererabravetAbstract:The culture of the lobster Panulirus interruptus is limited due to the lack of knowledge that allow the completion of all larval stages. This work presents data on daytime and nightime oxygen consumption and ammonia excretion in phyllosoma I and II of the red lobster Panulirus interruptus reared in the lab at 21 °C and feeding with enriched Artemia nauplii. During starvation, the oxygen consumption by larvae phyllosoma dropped from 5.29 in the first hour to 3.54 mg O2 g -1 h -1 after 14 h. The postabsorptive state was achieved after 13.5 h of starvation. This observation was taken into account to use starved larvae in our study. Oxygen consumption in the daytime was significantly higher than in the nightime in both larval stages. The levels of oxygen consumption (mg O2 g -1 h -1 ) during daytime and nightime were: 4.28

relative viable fecundity in the red lobster Panulirus interruptus randall 1840 in baja california mexico
Hidrobiologica, 2010Co-Authors: Eugenio Diaziglesias, Marysabel BaezhidalgoAbstract:The fundamental objective of this work is to estimate the Relative Viable Fecundity as the number of phylosomes born alive during hatching of the spawn, per longitude of the cephalothorax per female, of Panulirus interruptus in Baja California, Mexico, under laboratory conditions, with goals for its application on the culturing of the specie. The zones of origin of the spawning females were: Bahia Todos Santos, Punta Baja and Isla de Cedros, Baja California, Mexico. From the females between 62.0-97.2 Lc (mm), an average of 224,402 live phylosomes were obtained up to 3 days after hatching. The Relative Viable Fecundity resulted between 900.1-6,922.8 phylosomes/Lc (mm), with a mean of 2 795 phylosomes/Lc (mm). The relationship between the cephalothorax length (mm) and the number of phylosomes resulted: Phylosomes = 0.0083 Lc (mm)3.9046; r² = 0.615. The Relative Viable Fecundity estimated for this work resulted greater than that currently reported in the literature for Jasus edwardsii.

genetic variability and historic stability of the california spiny lobster Panulirus interruptus in the gulf of california
Fisheries Research, 2017Co-Authors: Francisco Javier Garciarodriguez, R Perezenriquez, Armando Medinaespinoza, Armando VegavelazquezAbstract:Abstract The California spiny lobster Panulirus interruptus ranges from California into the Gulf of California in Mexico. In Mexico, the lobster supports an economically important fishery. Lobsters in the Gulf of California may belong to a small and genetically distinct population. We determined the genetic diversity and population structure of P. interruptus , using mitochondrial DNA sequences of the control region and the 16SrRNA gene. Samples were collected in the Gulf of California, the west central and southwest coast of the Baja California Peninsula, and the United States. We found a slightly higher genetic diversity in the Gulf of California populations than in the Pacific, but no significant genetic differentiation was shown by an analysis of molecular variance. Using a spatial clustering model and Bayesian methods, the weak population structure was consistent with the absence of a phylogeographic pattern and genetic admixture analysis. However, mismatch distribution analysis suggests that lobster from the gulf represents a more stable and older population than the Pacific, which fitted a model of sudden population expansion. The clinal trend in several genetic parameters between the Gulf of California and the Pacific suggests a historical separation that has not yet resulted in a significant genetic differentiation by genetic drift, mainly because of the large size of the population. Implementation of independent fisheries management practices between these regions could be justified; however, biological and ecological information should be used to support genetic data.

genetic differentiation of the california spiny lobster Panulirus interruptus randall 1840 along the west coast of the baja california peninsula mexico
Marine Biology, 2006Co-Authors: Francisco Javier Garciarodriguez, R PerezenriquezAbstract:Identifying reproductive stocks in commercial species is relevant to fishery management strategies. We obtained muscle samples of California spiny lobster (Panulirus interruptus) from six localities along the west coast of the Baja California Peninsula and analyzed the genetic structure using mtDNA RFLPs. Our results indicated that all localities shared the same major haplotypes and showed a spatial homogeneity in the distribution of haplotype frequencies. An analysis of molecular variance indicated that only 0.84% of the genetic variability was explained by differences among localities and was not significantly different from zero. Weak divergences were found between Bahia Magdalena, the most southerly locality, in relation to other populations. Major oceanographic processes along this coast, combined with a long larval period that supports passive transport among localities, are suggested to explain the results.

population genetics of red spiny lobster Panulirus interruptus along the baja california peninsula mexico
Marine and Freshwater Research, 2001Co-Authors: R Perezenriquez, A Vega, S Avila, J L SandovalAbstract:Analysis of the genetic structure of the red spiny lobster (Panulirus interruptus) population was conducted along the Baja California Peninsula, Mexico. Samples for allozyme analysis came from Ensenada, Punta Eugenia, Punta Abreojos, San Juanico, and Bahia Magdalena (about 50 individuals each). Of 16 loci analysed, five were polymorphic (95% criterion) in at least one subpopulation. A significant mean value of FIS = 0.125 indicated some subpopulations departed from Hardy-Weinberg expectations; increased homozygosity was particularly evident for alleles EST-2*b and LAP*a at Ensenada and EST-2*c and EST-4*c at San Juanico. MeanFST = 0.101, which included 99% criterion polymorphic loci, was significant (P < 0.05), supporting a genetic structure throughout the species’ geographical range. Pairwise heterogeneity and FST tests showed no significant differences in allele frequencies between Punta Eugenia and Punta Abreojos, but several pairwise comparisons among the other locations, especially at the most variable loci, showed significant differences, supporting a hypothesis of genetic differentiation of P. interruptus into three subpopulations: southern, central, and northern Baja California. Oceanographic processes, such as semipermanent eddies south of Punta Eugenia that tend to retain phyllosoma larvae, may help generate this pattern. The implications of these findings for the management of the resource are also considered.

efecto de la emersion a corto plazo a dos temperaturas de exposicion aerea sobre parametros de calidad en cola de langosta espinosa Panulirus interruptus quality parameters of spiny lobster Panulirus interruptus tails as affected by short term emersion at two different air temperatures
2007Co-Authors: E Marquezrios, S Gomezjimenez, Victor Manuel Ocanohiguera, Francisco Javier Castilloyanez, R PachecoaguilarAbstract:The spiny lobster, Panulirus interruptus, is a valuable crustacean and most of its production is marketed live. In the northern fisheries of Baja California, Mexico, the animals are exposed to short-term emersion at different air temperatures during the live marketing procedures. This work evaluates the effect of short-term emersion (up to 10 h) at two air temperatures (7oC and 20oC) and of a 2-h recovery period on ATP, its related metabolites and some muscle quality parameters. Survival was 100% after all emersion times. No significant differences were found either in the adenylic energetic charge or in the levels of ATP and its related metabolites. The highest concentrations were found for AMP, IMP and INO, while ATP had the lowest levels. Muscle quality parameters such as water holding capacity and shear force remained similar to the control values. Although pH decreased slightly with emersion, it was very close to the control values after the 2-h recovery period. The overall results suggest that P. interruptus may perform physiological compensatory work after 10 h emersion even at 20oC without significantly affecting the muscle quality.
