***Data***

> Catch time series.csv
Annual catch time series at three spatial scales.

	year - year for which annual catch is reported
	fao - Madagascar's annual catch (tonnes) of lobster, FAO data set
	regional - Annual catch (tonnes) for the Fort Dauphin regional lobster fishery (defined in text of paper), DRRHP/URL dataset
	sainte_luce - Annual catch (tonnes) for the Sainte Luce lobster fishery, DRRHP/URL dataset

> Numbers of boats data.csv
For all survey days when acitve and inactive boats were counted at both landing sites (Main and Lodge) in Sainte Luce.

	date - date in format dayXX/monthXX/yearXXXX
	main_inactive - number of inactive boats at the main landing site
	main_active - number of active (any activity) boats at the main landing site
	lodge_inactive - number of inactive boats at the lodge landing site
	lodge_active - number of active boats at the lodge landing site

> Data for effort means_fishers and pots.csv
Used for reporting means and used as part of the calculation of the 2015 catch in Sainte Luce.

	date - date in format dayXX/monthXX/yearXXXX
	no_of_pots_checked - total number of pots checked by fishermen in that boats on that trip
	no_of_fishers - number of fishers in the boats being queried
	

> CPUE model dataset_final.csv
Used to produce Zero Altered Negative Binomial Model (ZANB) and figure 3. Note all records are form the Main landing site.

	month - full name of the month
	year - year XXXX
	mon_yr - month (first thre letters) and year (last two digits) combined in the format XXX_'XX
	NTZ status - idicates whether the No Take Zone (NTZ) was 'Open' or 'Closed'
	pots - total number of pots checked by fishermen in that boats on that trip
	fishers - number of fishers in the boats being queried
	lobsters - the total number of lobsters caught by the boat being queried on that trip
	kg - the total weight of lobsters coaught by the boat queried on that trip
	CPUE_num - The standardised Catch Per Unit Effort (CPUE) in lobsters/boatday.  CPUE was standardised to the mean number of pots used per boat for the entire survey period, 19.6 pots (sd = 11.4, n = 3103). 


> Data for BAC calculation
For the purpose of estimating lobster catch in Sainte Luce in 2015 the Boat Activity Coefficient (BAC) was calculated as described in the paper and supporting information. BAC calculated for each day with the mean for the month used in the catch estimation.

	date - date in format dayXX/monthXX/yearXXXX
	inactive_pirogues - the total estimated number of boats based at the main landing site not engaged in lobster fishing on that date
	active pirogues - the total estimated number of boats based at the main landing site engaged in lobster fishing on that date
	BAC - Boat Activity Coefficient = active pirogues/(active pirogues+inactive_pirogues)

> Catch composition data
Data used for catch composition analyses.

	date - date in format dayXX/monthXX/yearXXXX
	species - species*
	total_length - The TL was measured (± 0.5 mm) from the rostrum to the posterior edge of the telson 
	carapace_lenght - The CL was measured (± 0.5 mm) from the base of the frontal horns to the posterior edge of the carapace.
	weight - wet weight in kg
	sex - sex
	berried - visible presnece of egg mass (yes/no)
