The system consists of 2 adjoining 150 litre aquaria, one functioning as the water-conditioning tank and the other as the principal rearing tank. Water quality remained high with biological and mechanical filtration, physical adsorption and ultraviolet-light disinfection taking place exclusively in the conditioning tank. The pH ranged from 7·58 to 8·00 and ammonia and nitrite levels never exceeded 0·004 mg/l and 0·198 mg/l, respectively. Nitrate levels were maintained at 40 mg/l or less with no…

Survival of healthy, wild-caught animals, commonly 4-6 months and up to 8 months, is apparently limited more by endogenous factors concerned with sexual maturation and lifespan than by aquarium conditions.

Cultivo experimental de Octopus mimus, Gould 1852 en el Perú

Octopus mimus Gould, 1852 is an important benthic resource in the Peruvian artisanal fishery and is always in demand on the international market and the growth rate was greater than that of those in the lines of culture.

Life cycle of the marbled octopus, Amphioctopus aegina (Gray) (Cephalopoda: Octopodidae) reared in the laboratory

Overall similarities in these cephalopod taxa attest to the fitness of a life-history strategy involving production of planktonic offspring from benthic adults.

Octopus joubini (Mollusca: Cephalopoda): a detailed study of growth through the full life cycle in a closed seawater system

Twenty individual pygmy octopuses, Octopus joubini, were reared at 25°C from hatching to maturity on a quantified diet of live crabs in closed (recirculating) natural seawater systems and showed slight allometric growth resulting in changing body proportions through the life cycle.

Mysid culture: lowering costs with alternative diets.

The production, survival and growth of mysids fed the rotifer-exclusive diet was significantly lower than those of the other diets (P < 0.05), and the following feeding regime is recommended: feed rotifers during the first 20 days of the life cycle and then feed a diet of Artemia nauplii andRotifers (66%).

A new species of pygmy Paroctopus (Cephalopoda: Octopodidae): the smallest southwestern Atlantic octopod, found in sea debris

The description of this new species, living in a novel habitat of human debris in shallow water off Brazil, offered an opportunity not only to evaluate the relationship among the small octopuses of the western Atlantic, Caribbean and eastern Pacific, but also their adaptation to the Anthropocene period.


This is the first study so far dealing with the cuttlefish Sepia pharaonis morphology, anatomy and posible infection with parasites in the marine waters off Kuwait.

Prey Capture, Ingestion, and Digestion Dynamics of Octopus vulgaris Paralarvae Fed Live Zooplankton

This study shows for the first time in a live cephalopod that octopus paralarvae attack, immobilize, drill, and ingest live cladocerans and copepods with 100% efficiency, which decreases dramatically to 60% on decapod prey (Pisidia longicornis).



Observations on Octopus joubini: Some aspects of reproductive biology and growth

Observations were made on the brooding behavior of 10 laboratory reared female Octopus joubini, including egg laying, care of the eggs, feeding during brooding, and survival of the female from the

Observations on the life history of the blue-ringed octopus Hapalochlaena maculosa

The unusual life-history of H. maculosa suggests that it is a highly evolved octopus species, and its direct development, simple diet, and rapid rate of growth make the animal relatively easy to cultivate for experimental or pharmacological purposes.

Fish and invertebrate culture;: Water management in closed systems

A completely rewritten edition of this simple, concise handbook on water quality control in closed-system environments, focusing on aquariums, demonstrates that accumulating toxic metabolites are the primary limiting factors in aquatic animal culture and that removing them on a continuous basis should be the foremost objective in routine water management.

New data on reproductive biology and growth of Octopus vulgaris

The problems of reproduction of Octopus vulgaris and the seasonal distribution in the sea of planktonic larvae, benthonic juveniles and adults are discussed. The influence of environmental factors on
