Bower JR, Seki MP, Young RE, Bigelow KA, Hirota J, Flament P. The water flow is controlled by contractions of the radial and circular mantle cavity muscles. One limitation with such approaches is the need for an environmental predictor available before the start of the fishery, which could thus be used to Cephalopod Life Cycles catch or effort limits at the start of the fishing season.

Depending on the species and its swimming abilities, distances between spawning and feeding grounds may vary from tens of kilometres for nearshore sepiids to hundreds of kilometres for offshore loliginids and even thousands of kilometres in nektonic ommastrephid and gonatid squids. There was a considerable overlap between the hatchling sizes of benthic and planktonic species for intermediate sizes classes, although the frequency of planktonic hatchlings in these classes was very low.
The varying synchrony between hatching of larvae and plankton production means that hatching in the right place and time will be decisive for first feeding success and thus, survival and growth. The increase in fishing Cephalopod Life Cycles was attributable to increased numbers of large jigging vessels fishing on the high seas, mainly for I.
FAO Species Catalogue for Fishery Purposes. Unlike most modern cephalopods, most ancient varieties had protective shells. Coincident with the development and proliferation of aquaculture, parasites and other pathogens have proliferated e. Thus, both retrospective assessments and forecasting can be used to plan future fishing—although the former is perhaps the least useful approach for species which show wide year-to-year fluctuations in abundance.
The terrifyingly powerful of may have been inspired by the octopus or squid, the octopus's body representing the severed head of , the beak as the protruding tongue and fangs, and its tentacles as the snakes.
, modifying host phenotypes in order to increase the likelihood that they will be predated on by their definitive hosts ; , mechanisms that have yet to be explored in cephalopod hosts.
