A nivel mundial, se está evaluando el bienestar en peces, mediante técnicas no invasivas como el monitoreo del comportamiento por videograbaciones y la respuesta a situaciones generando un estrés en los animales o EAE. Este documento revisa los principios y métodos básicos y más comunes utilizados en acuicultura para evaluar los EAE y su impacto so...

En esta investigación, se estudió el comportamiento habitual de juveniles de lisa adaptados al cautiverio, el cual se clasificó en una categoría de “actividad” con cuatro patrones comportamentales (descanso, normal, alta y frotar) y una categoría de “alimentación” (fondo y superficie).

Stress coping styles (SCS) are defined as a coherent set of individual physiological and behavioural differences in stress responses that are consistent across context and over time. Nowadays, an increased attention has been paid to fish welfare in aquaculture production and to consistent behavioural response to stress in captivity, since these asp...

Identifying Stress Coping Styles (SCS) in new species of interest for aquaculture has important implications for its future domestication and adaptation to captivity. Individual variability allows to select the potential positive characteristics for fish production. The main aim of this study was to identify phenotypic individual differences and ch...

Aim of study: To describe the common behaviour of flathead grey mullet (Mugil cephalus) under rearing conditions. Area of study: Tepic, Mexico. Material and methods: Behaviours exhibited by mullets were videorecorded with submersible cameras installed inside of three tanks. A total of 690 min per day (07:30 - 18:30 h) were recorded per tank durin...

El presente trabajo tuvo por objetivo inducir al desove a hembras maduras de Paralichthys asdpersus (lenguado) utilizando una hormona análoga a la gonadotropina (GnRHa) y determinar la calidad de huevos y larvas obtenidas en los periodos de 2014 y 2015. Se seleccionaron hembras con ovocitos en maduración avanzada (542.61 µm), que desovaron luego de...

This study evaluated the acute toxicity and sublethal effects of nitrite on oxidative stress parameters in early juvenile Brazilian flounder, Paralichthys orbignyanus. Fish were exposed to six concentrations of nitrite: 20, 40, 80, 170, 330 and 550 mg NO2⁻N-L⁻¹, plus a control with no added nitrite, all in triplicate for 96 h. Every 24 h, the tanks...

This research described the common behaviour of grey mullet (Mugil cephalus) under rearing conditions. The different behaviours exhibited by mullets were videorecorded with submersible cameras installed inside of three tanks. A total of 690 minutes per day (07:30-18:30 hours) were recorded per tank during a week. Afterwards, an ethogram was elabora...

Peruvian grunt Anisotremus scapularis is distributed from Ecuador to Chile and it is considered an important aquaculture resource in Peru. Knowledge of embryonic development is crucial because it is part of the basic biology of a species. The aim of this study was to describe the embryonic stages of Peruvian grunt. The eggs were obtained by natural...

Larviculture is a critical stage during the production of marine fish species and it is related to highest mortalities. The production of juveniles depends on a successful larval rearing, consequently the importance to investigate all aspects related to this culture stage, such as the stocking-density which is the extreme importance to improve cult...

The aim of this study was to evaluate two new types of experimental weaning microdiets for fish larvae, using the same formulation, but with different manufacturing processes, microextrusion marumerization (MEM) and particle-assisted rotational agglomeration (PARA). Both microdiets were compared to a commercial microdiet, Otohime™ (OTO), during the...

M. 2018. Manual para acondicionamiento y reproducción de chita Anisotremus scapularis. Inf Inst Mar Perú. 45(2): 263-276.-El presente manual está basado en la experiencia y resultados obtenidos entre el 2013 y 2016 en el Laboratorio de Cultivo de Peces del Imarpe. Se detalla procedimientos de los sistemas de recirculación de agua de mar y caracterí...

La “Chita” o “Sargo” Anisotremus scapularis (Tschudi, 1846) se distribuye desde Manta en el Ecuador a Antofagasta, Isla Cocos en Chile (Chero et al., 2014). Según el Plan Nacional de Desarrollo Acuícola – (D.S. N° 30-2001-PE) y el Programa Nacional de Ciencia, Desarrollo Tecnológico e Innovación en Acuicultura 2013-2021 (C+DT+i), la chita es consid...

Uno de los factores que influyen en el crecimiento y la sobrevivencia larvaria es la densidad de cultivo (DC), la cual afecta a la calidad del agua, limita el espacio y aumenta la agresividad de las larvas (Sakakura & Tsukamoto 2002, Szkudlarek & Zakés 2007). Actualmente, se realizan diversos estudios que contribuyen al manejo de la chita A. scapul...

Peruvian grunt Anisotremus scapularis is a specie with high aquaculture potential and the knowledge of the early embryonic stages and larval rearing of this species permitted to obtain useful scientific information for the development of technological packages for the culture of this specie. The objective of the present study is to describe the emb...
