Settlement of the spiny lobster Panulirus in atus (Bouvier, 1895) postlarvae in the southeastern Gulf of California, Mexico

Abstract

ABSTRACT. The settlement of Panulirus inatus postlarvae in the southeastern Gulf of California was monitored approximately every week at one location (Puerto Viejo Bay) in Mazatlán Bay, from november 2009 to October 2010. Each sampling date was assigned to the lunar phase. Modied sandwich collectors were used to capture postlarval lobsters. Three collectors were used to examine pueruli settlement. A total of 238 P. inatus pueruli were collected, which included 40 pueruli (17 %) and 198 post-pueruli (83 %). Settlement was highest using collector number one (140 pueruli), and november 2009 was the month with the greatest total number of animals (121). Signicant dierences were found with respect to the lunar phase, but the higher settlement in this study occurred during the new moon phase.

El asentamiento de la postlarva de Panulirus inatus en el sureste del Golfo de California fue revisado cada semana en una estación de muestreo en la zona denominada Ensenada de Puerto Viejo de la bahía de Mazatlán, Sinaloa, de noviembre 2009 a octubre 2010. Cada fecha de muestreo fue asignada de acuerdo a la fase lunar. En este estudio se utilizaron colectores tipo Sandwich modicado para capturar las postlarvas de langosta. Tres colectores fueron usados para examinar el asentamiento de puérulos de langosta. Se colectó un total de 238 organismos de P. inatus, 40 puérulos (17 %) y 198 postpuérulos (83 %). El mayor asentamiento fue en el colector número uno (140 puérulos) y el mes de noviembre fue cuando se obtuvo la mayor cantidad de organismos (121). Se encontraron diferencias signicativas entre las postlarvas y fase lunar, pero los mayores asentamientos ocurrieron en la fase de Luna nueva.Palabras clave: Golfo de California, Panulirus inatus, asentamiento de puérulos, Colector Sandwich modicado.

Benthic Amphipods (Crustacea) in Panulirus Spiny Lobster (Crustacea) Postlarvae Collectors

“…The most common amphipod genera were Bemlos and Tritella, which did not coincide with [8] who pointed out Rhepoxynius and Metharpinia as the most abundant in Petatalco bay, Guerrero, in the southern Mexican Pacific [3], found two new species of amphipods of the genus Caprella (Caprella calderoni and Caprella mercedesae), but both species were collected by the oceanographic vessel "El Puma", in the central region of the Gulf of California, that is, to a greater area and depth than this study determined a composition of 16 species distributed in five genus of amphipods, resulting in this study with two genera less than the present investigation, although the latter authors analyzed the amphipods from Baja California Sur (Mexico) to Peru, compared to this study that was carried out only in Cospita bay, Sinaloa, northwest of Mexico. The results obtained here for the order Amphipoda, with four superfamilies, seven families, seven genera and three species, represent an important taxonomic interest for this geographical area, since there are not records of benthic amphipods in Cospita bay, and also obtaining of 170 amphipods in artificial collectors for Panulirus lobster juveniles, represents an alternative microhabitat for this community of benthic crustaceans as indicated by [14] for the southeastern Gulf of California. The species that make up the minor crustaceans and particular the amphipods, since many of these species are part of the food chain of the trophic chain and most likely the success of higher species for the marine ecosystem to function properly [20][21][22].…”

“…In thus study, seven families, seven genera and three species were determined, this information is not less if this study is considered as the first recorded of amphipods associated with juvenile Panulirus lobster, and also as the first report of benthic amphipods in the northwest of the mexican Pacific.. The collection of 170 amphipods in the present study through the use of the algae collector designed by [14], it can be considered an excellent half of recruiting a great diversity of species and larvae of minor crustaceans such as amphipods and other marine benthic invertebrates [4]. However, according to [9] the taxonomic identification of the amphipods species is difficult due to the little information on the species in the scientific literature of the Mexican Pacific, although the seven families mentioned here were reported by [4] for amphipods in the Eastern Tropical Pacific.…”

“…On the Sinaloa, Mexico coast, [13] reported a new geographic distribution for the Mazatlán bay of Paracaprella pusilla amphipod in oyster boxes. While [14] analyzed the presence of spiny lobster juvenile (pueruli) in artificial collectors in the bay of Mazatlán, although these authors did not report the presence of amphipods. However, in the present investigation, benthic amphipod species were determined for the first time using artificial collectors that simulate the presence of marine algae for spiny lobster hatchlings.…”

Social-ecological connectivity and management factors of puerulus (Panulirus spp.) fisheries in the Western Coastal Waters of Lampung Province

“…The more efforts there are, the number of catches will increase and decrease the CPUE value. A decrease in CPUE values indicates a decrease in fish stocks in the catchment area [16].…”

Ontogeny of the Cytochrome P450 Superfamily in the Ornate Spiny Lobster (Panulirus ornatus)

“…Spiny lobsters begin their life as a tiny egg that hatches into a transparent, leaf-like organism called phyllosoma [19]. This is an oceanic phase, which can last up to two years in some species [20], during which the animal may be entrapped in water currents known as gyres, where they actively predate on zooplankton to supply their nutrition for growth [21].…”
