Abstract
Three feeding experiments, using live mysid shrimp, grass shrimp or fish fry as prey for 1-, 30- and 60-day-old cuttlefish were conducted to determine the efficiency of each dietary source in relation to cuttlefish size and age. Additionally, a fourth experiment using fish fry and grass shrimp, but previously frozen, was also conducted. The results showed that when 1-day-old cuttlefish were fed mysids, grass shrimp or fish for 4 weeks, mysids were the best prey, but only during the first week. From this moment until the end of the experiment, the best growth rate was when cuttlefish were fed grass shrimp. Cuttlefish fed fish fry showed the poorest growth rate throughout the experiment. Similarly, cuttlefish aged 30 or 60 days fed grass shrimp or fish fry had the best growth rates when fed grass shrimp. When cuttlefish were fed live fish, survival increased with size of cuttlefish (73.3%, 91.7% and 100% for 1, 30 and 60 days cuttlefish, respectively). In the fourth experiment, using frozen diets, overall acceptance of each diet (feeding rates) was the same for fish and shrimp. However, lower growth was obtained when cuttlefish were fed fish compared to grass shrimp. This lower growth was due to a lower food conversion (28% vs. 41%). Since cephalopod paralarvae and juvenile most likely need prey rich in polyunsaturated fatty acids (PUFA), phospholipids and cholesterol, and a moderate content in neutral lipids, we have analyzed the biochemical compositions of the different prey to evaluate the influence of this factor on growth and survival.
Effect of enriched natural diet on survival and growth of juvenile cuttlefish Sepia officinalis L.N. Kouetaa, , , E. Boucaud-Camoua and B. Noelb

Abstract
Juvenile cuttlefish hatched in the laboratory were reared for 30 days with different enriched diets, in spring and in summer. The groups fed an enriched natural diet exhibited a high rate of survival even when seawater quality decreased during the summer. The natural diet enriched in polyunsaturated fatty acids (PUFA) induced faster growth in juvenile cuttlefish; the stimulating effect of PUFA on growth was evident during the very early juvenile stage, and the benefit resulted is conserved during further growth. The maximum daily ration was lower in groups fed with the enriched diet than in the control.

These data indicate the importance of n?3 PUFA such as docosahexaenoic acid (DHA; 22:6n?3) and eicosapentaenoic acid (EPA; 20:5n?3) in cephalopod juvenile nutrition.

Maybe sticky this?

I am looking to get in to cuttlefish by raising from eggs, and I found these studies buried in some other threads. To me they really help reinforce the importance of mysis shrimp (in the beginning) and the use of amphipods, so for those who haven't seen it I think a sticky might be in order.

Abstract

The effects of feeding two alternative live prey (exclusively caprellids (Caprella equilibra) or several species of gammarids, mainly Ericthonius brasiliensis, Jassa marmorata and Elasmopus sp.), to cuttlefish hatchlings were compared to feeding mysids (Mesopodopsis slabberi), which are normally used during the first weeks of the life cycle. Weight (g) and growth rates (GR, % BW d? 1) were determined. Cuttlefish hatchlings fed with mysids and gammarids grew faster (6.7 ? 0.4 and 5.7 ? 0.9% BW d? 1, respectively) compared to caprellids (1.6 ? 0.2% BW d? 1). Survival was higher (96.7 ? 5.8%) for hatchlings fed mysids, compared to 83.3 ? 15.3% and 76.7 ? 5.8%, for those fed gammarids and caprellids, respectively. According to the results obtained, gammarids could be used as an alternative prey to mysids, while Caprella equilibra did not deliver appropriate growth rates and should be disregarded as alternative prey for rearing early stages (hatchlings) of Sepia officinalis. This is the first study revealing a successful use of amphipods, mainly gammarids, as alternative prey for cuttlefish hatchlings.

Cephalopds need live prey to be cultured during the first part of their life, Mysids and
Artemia are the only live prey that promotes better growth. The lack of alternative food
to culture early stages is an important bottleneck for cephalopod large-scale culture.
Amphipods (caprellids and gammarids) could be a potential alternative prey since they
are easy to collect, tend to breed throughout the year and have short life spans.
Furthermore, they could be less expensive to be cultured, as they can feed on
suspended organic matter. Two experiments were carried out. The first using Sepia
officinalis hatchlings fed for 21 days with three diets; saltwater gammarids, caprellids,
and mysids (control), and the second with Octopus maya hatchlings fed for 15 days
with saltwater gammarids, freshwater gammarids, and artemia (control). Animals were
individually weighted at the beginning and end of the experimental period. Daily growth
coefficient (DGC, %day?1) was determined. According to the results obtained in growth
rates of S. officinalis with mysids and gammarids (6.7?0.4 and 5.7?0.9 % DGC d?1,
respectively), marine gammarids could be used as an alternative prey to mysids in the
culture of S. officinalis. In O. maya experiments, marine gammarids were the best diet
showing double growth rate than control with artemia (8.4?0.27 and 4.84?0.15 % DGC
d?1). This is the first study revealing a successful use of amphipods, mainly gammarids,
as alternative prey for cephalopods hatchlings culture.

This seems interesting, would've been something I wondered on when I was working at the aquarium since I was the "go-to" guy for "things with tentacles".

Early weaning of cuttlefish with frozen grass shrimp

Early weaning of cuttlefish (Sepia officinalis, L.) with frozen grass shrimp (Palaemonetes varians) from the first day after hatching

Article first published online: 15 MAY 2012 DOI: 10.1111/j.1365-2109.2012.03186.x © 2012 Blackwell Publishing Ltd

A study from Antonio Sykes and his colleagues (Portugal). They operate a facility that specializes in raising officinalis. We met last year at Euroceph and heard a lot about this facility and the results they produce. Their work is very promising, would like to see them succeed and expand.

Captive behaviour of cephalopods, M.K. Anil Principal Scientist, Molluscan Fisheries Division

Introduction
Cephalopods are the largest and most active invertebrates. India exports frozen cuttlefish and frozen
squid to countries such as Japan, USA and the European Union. Cephalopods are unique because they
have 85% protein by dry weight (16-21% by wet weight) and are considered a delicacy in seafood
restaurants. Recent years have witnessed a significant amount of research interest in cephalopod culture
and behaviour, in order to develop technology for commercial farming as well as to produce multiple
laboratory generations for research in neurobiology and also to gather information for fishery
management. In India, first major success in captive rearing studies of Cephalopod was achieved in 1999
with the cuttlefish Sepiella inermis at Tuticiorin Research Centre of CMFRI. Since then CMFRI has been
working on squids, Uroteuthis (Photololigo) duvaucelii, Sepioteuthis lessoniana; cuttlefish, Sepia
pharaonis, and octopus Octopus dollfusi. However, research was mainly focused on the cuttlefish S.
pharaonis and squid, S. lessoniana.
